coatings on Ti6AI4V were formed using double glow discharge technique. The fundamental coating properties, such as the phase, hardness and elastic modulus were investigated. The tribological performances of the coatings in dry wear condition were studied by means of ball-on-disc wear machine. The experimental results showed that the thickness of the Mo-N hard coating was about 10 μm. The coating......
Effect of Thermal Shock and Oxidation on Mechanical Property of Carbon/Carbon Composites with a Silicide Coating () 摘要:A SiC whisker-toughened MoSi_2-SiC-Si coating was prepared on carbon/carbon (C/C) composites surface by a two-step technique of slurry and pack cementation, and the effects of thermal shock and oxidation on the mechanical property of the coated C/C were studied. The flexural......
,利用钨的氧化物在水蒸气中的挥发特性及其化学气相传输,在金刚石表面镀覆金属钨.结果表明,该方法可在金刚石表面镀覆上一层覆盖面达到90%以上的金属钨膜,且生成稳定的碳化物WC和W2C,得到由难熔金属钨包覆的金刚石. 关键词:金刚石;钨;镀覆 中图分类号:TQ 164 文献标识码:A Novel method for coating... Material Corporation, Guilin 541004, China) Abstract: A novel method for coating tungsten on diamond was put forward. In the method, using the volatilization of tungsten oxides in water vapor and chemical......
composites is the key technique for ablation resistant nozzles. Based on the TaCl5-C3H6-H2-Ar active system, the TaC coating can be deposited on the C/C composite surface by CVD process. Its found...

Electrophoretic deposition of titanium/silicon-substituted hydroxyapatite composite coating and its interaction with bovine serum albumin XIAO Feng-juan(肖凤娟), ZHANG Ying(张 颖), YUN Li-jiang(云立江... substrate were prepared by electrophoretic deposition technique with the addition of triethanolamine (TEA) to enhance the ionization degree of Si-HA suspension. The surface structure was characterized......
,and well adherent conversion coating of magnesium hydroxide has been formed on bioresorbable magnesium disks by means of a hydrothermal technique Electrochemical results indicate that the coating brings about a significant reduction in magnesium corrosion in phosphate buffered saline(PBS)solution.It is also observed that corrosion resistance of the coating increases with an increase in treatment......
Nano-Composite Superfine Nickel Powder Double Absorbent Coating Designing () 摘要:We adopt a definite procedure to compound traditional absorbing material-superfine powder nickel and nano -SiC... material, but each component of the composite material must have matched electromagnetic parameter with another. For matching double-coating structure, it ought to modulate the correlativity of each......
