An electrodeposition technique was developed for fabricating bioactive hydroxyap-atite(HA) coating on Ti-6Al-4V alloy at relative low temperature. XRD, SEM and ICP/AES were used to characterize the structure, morphology and chemical composition of the coatings. The galvanostatic electrodeposted HA coating is of 1.62 Ca/P molar ratio and has a uniform and porous structure, which is similar with the structure and composition of hu-man bone. The reaction mechanism and influence of experimental conditions on HA coatings are also discussed.

Configuration interaction tenichque is applied to the valence bond theory. Virtual VB orbitals are built, which are localized and orthogonal to their corresponding occupied orbitals and the excited VB structures are defined, which come from their corresponding fundamental VB structures. The testing calculations of H 2, LiH, HF show that the VB results using CI method match those of the molecular orbital based on the coupled cluster CCSD method, and the CI technique may become a useful tool in VB method.
