摘      要:In this paper, the single factor variable method is used to analyze the influence of Titanium diamond-plated on nickel based coatings on titanium alloys. The thermal stress change, phase composition, element distribution, microhardness and wear resistance mechanism of the coating were discussed;The cladding layer is mainly composed of diamond, TiC, Cr23C6, NiTi2 and other phases;When the content of Ti coated diamond is 4%, The grain size is significantly reduced;The microhardness of cladding layer reaches 68 HRC. The cladding shows little wear,the wear coefficient is 0.21, and the wear volume of friction pair(ZrO2 ball) is 1.29*10-4cm3;The results show that adding 4% Ti coated diamond to the coating can reduce the crack sensitivity between the coating and the substrate, and the nickel based diamond coating with good performance can be prepared. © 2023, The Authors.
