A series of W-Al nanolayer coatings were deposited with varying content of aluminum from 0 at.% to 65 at.% by a unbalanced magnetron (UBM) sputtering system. The as-deposited coatings were investigated first. Then, the coatings were oxidized aiming to study their oxidation behavior. SEM, TEM, XRD, GDOS and nano-hardness tester were used. The results showed that the Al content had a significant effect on the performance of W-Al coatings. The hardness of as-deposited and oxidized coatings decreased with increasing Al content. The pure W coating was heavily oxidized. As the Al content increased, the oxidation decreased fast and then remained stable as the Al content was higher than 45at.%. The effects of formed oxides on hardness were discussed. © 2015 Trans Tech Publications, Switzerland.

W, W-15 at-%Al, W-30 at-%Al and W-45 at-%Al coatings were synthesised by using a reactive four-target DC closed field unbalanced magnetron-sputtering ion plating system. Structure, morphology, composition, hardness and adhesion were studied by using an X-ray diffractometer, an energy dispersive spectrometer, a scanning electron microscope, a scanning transmission electron microscope and nanohardness and scratching testers. Wear performance was evaluated by using a pin-on-disk wear tester. The sputtering deposition of this binary system led to the formation of single-layer W-Al coatings as a result of complete dissolution of the Al atoms into the W lattice during the depositing process. The W-15 at-%Al coating showed improved wear resistance as compared with the W coating. © 2014 W. S. Maney & Son Ltd.

Tribological behaviour of NiCrBSi-WC(Co) coatings

引用

作者： Yao, S.H. Bachelor Degree Program in Technology Management Chang Jung Christian University Gueiren District Tainan71101 Taiwan

Parts working under extreme conditions are in need of surface coatings to achieve better performance and longer service life. NiCrBSi alloys have been a good choice against wear combined with corrosion at high temperature but need further improvements. In this work, a series of NiCrBSi-WC(Co) coatings with WC(Co) content from 0 wt-% to as high as 80 wt-% were prepared using a high velocity oxy-fuel spraying process. The influences of the WC(Co) content on the wear behaviour of the metal matrix composite coatings were studied using an SRV reciprocating sliding wear system. The relationship of the wear mechanism and the WC(Co) content was discussed, and an optimal WC(Co) content was proposed according to the study results. © 2014 W. S. Maney & Son Ltd.

The new trends and developments in the novel functional materials and material research innovations presented at the 3rd Global Conference on Materials Science and Engineering (CMSE2014), which was held on 20-23 October 2014 in Shanghai, China, is discussed. R. Toyoda, M. Tawata, M. Hashimoto, and Y. Matsumura presented 'Internal stress control of transition-metal thin films', where the effects of ion bombardment parameter Pi on the internal stress of thin films were evaluated. X.G. Wang, Z.L. Chen, and X.Y. Wang presented their study 'Measurement of the interface characteristic based on ultrasonic longitudinal wave', which provided a lucrative alternative to conventional ultrasonic techniques, since it allows one to avoid the mutual superposition of reflected waves at the same thin coating interface. P. Wang and C.Y. Zhao presented their 'Study on reducing railway noise by porous concrete sound-absorbing panel', which is crucial for noise reduction near the railway lines. In the paper entitled 'Numerical study on the heat preservation of the ladle used for twin-roll strip casting', J.H. Dong, M. Chen and N. Wang developed a 3D mathematical model, in order to analyze the heat transfer and temperature drop on the ladle using the finite volume method.

The objectives of Human Engineering (HE) are generally viewed as increasing human performance, reducing human error, enhancing personnel and equipment safety, and reducing training and related personnel costs. There are other benefits that are thoroughly consistent with the direction of the Navy of the future, chief among these is reduction of required numbers of personnel to operate and maintain Navy ships. The Naval Research Advisory Committee (NRAC) report on Man-Machine technology in the Navy estimated that one of the benefits from increased application of man-machine technology to Navy ship design is personnel reduction as well as improving system availability, effectiveness, and safety The objective of this paper is to discuss aspects of the human engineering design of ships and systems that affect manning requirements, and impact human-performance and safety The paper will also discuss how the application of human engineering leads to improved performance, and crew safety, and reduced workload, all of which influence manning levels. Finally, the paper presents a discussion of tools and case studies of good human engineering design practices which reduce manning.

There is a very large demand for basic telephone service in developing nations, and remote parts of industrialized nations, which cannot be met by conventional wireline and cellular systems. This is the world's largest unserved market. We describe a system which uses recent advances in active phased arrays, fast-packet switching technology, adaptive routeing, and light spacecraft technology, in part based on the work of the Jet Propulsion Laboratory and on recently-declassified work done on the Strategic Defense Initiative, to make it possible to address this market with a global telephone network based on a large low-Earth-orbit constellation of identical satellites. A telephone utility can use such a network to provide the same modern basic and enhanced telephone services offered by telephone utilities in the urban centres of fully-industrialized nations. Economies of scale permit capital and operating costs per subscriber low enough to provide a service to all subscribers, regardless of location, at prices comparable to the same services in urban areas of industrialized nations, while generating operating profits great enough to attract the capital needed for its construction. The bandwidth needed to support the capacity needed to gain these economies of scale requires that the system use K(alpha)-band frequencies. This choice of frequencies places unusual constraints on the network design, and in particular forces the use of a large number of satellites. Global demand for basic and enhanced telephone service is great enough to support at least three networks of the size described herein. The volume of advanced components, and services such as launch services, required to construct and replace these networks is sufficient to propel certain industries to market leadership positions in the early 21st Century.

USS Ingraham (FFG-61) is the prototype ship for NavSea's Advanced Technical Information System (ATIS). ATIS is a digital technical library, which holds on optical disks the ship's 2,000 technical manuals and 73,000 drawing sheets. It contains a detailed ship's configuration index (derived from SCLSIS) to lead the user to the proper drawing or manual, and it replaces the ship's aperture cards and the second (library) copy of the technical manuals. ATIS, and the data standards established and tested through ATIS development, will be the technical library portion of micro-SNAP and SNAP III. It also forms an important part of NavSea's plans to utilize EDMICS data. This paper describes the goals and technical concepts behind the development of ATIS. Problems encountered, solutions developed, and lessons learned are detailed. Special attention was paid to the application of the Computer Aided Acquisition and Logistic Support (CALS) standards, problems caused by conflicts and ambiguities in those standards, the standards. Original program goals are compared with actual operational experiences. Plans for future expansion are outlined, including applications of this technology in the availability planning and execution process. A comparison is developed among the various methods of optical imaging and their costs and benefits.

The SA'AR-5 Corvette program is the first major warship construction to be entirely accomplished using a 3-dimensional, interference checked computer based design. This paper discusses the organization and approach used to create the design models which form the basis for interference checking as well as the source of extracted production data. The design or product model is the nucleus of the computer data base that defines the configuration of the entire ship. The data base includes geometry, weight, and material, as well as production control data. The ability of the computer to link such diverse information is the key to maintaining configuration control during the course of the design and construction. The ease with which formatted manufacturing data (both N.C. fabrication and installation) can be extracted enables the preparation of detailed packages containing the desired geometry as well as the associated material and sequencing data, thus assuring the producibility of the design. The SA'AR-5 design is CAD/CAM's state of the art in U.S. shipbuilding.
