Friction and Wear Properties of TiAl and Ti2AlN/TiAl Composites at High Temperature孙东立,SUN Tao,WANG Qing,HAN Xiuli,GUO LinlinSchool of Materials Science and Engineering,Harbin Institute of Technology摘 要:The high-temperature friction and wear properties of TiAl alloys and Ti2 AlN/TiAl composites(TTC) in contact with nickel-based superalloy were......
extreme-pressure( EP), anti-wear(AW) , friction reducion and self-repairing properties. The lubrication and repairing mechanism is inferred that SiO2/ZnO combined nanoparticle is sedimented on the surface of steel, the lower surface film is formed under the high temperature and high pressure. The film possess excellent anti-wear , friction-reducing and repairing properties. 关键词:SiO2; ZnO......

Research Institute of Surface... on the surface of magnesium alloy AZ91D to improve its wear resistance. The wear behavior was investigated by test of ball on disc sliding. The composition and microstructure of the coating were also analyzed......
properties to the alloy system under specific conditions[9-11,22-31,41]. Wear being a surface phenomenon is a complex process of material removal. This is evident from a variety of material and test... particles) Table 2 Properties of experimental zinc-based alloys 3.2 Slurry wear response Wear rate of the samples was plotted as a function of traversal distance (Figs.3 and 4) and sand content......
deposits have superior properties against wear than hard chromium deposits under dry sliding condition. Under oil sliding condition, except their better wear resistance, the deposits can protect...]. In the present research, many people discussed the effects of electroplating parameters and bath composition on deposits, but nobody discussed the wear and corrosion properties of ternary tungsten......
