- Dehydration rate increases with the increasing of additive concentration, and then decreases.
- It turned out the tussah silk fibroin powder with short hydrolysis time and large additive concentration had the eminent capability of anti-ultraviolet rays.
- The ceramic coating becomes smooth and has a better cohesion with the substrate. The content of rutile TiO_2 increases while the Na_2Mo_7O_(24) additive concentration increases.
- The effects of additive concentration, load applied and operating time on its antiwear and friction reduction properties as function of additive concentration in oil have been evaluated on a four-ball tester.
- Based on the data obtained,the relationships among the surface tensions and the additive concentration of the lubricating oils and the temperature were derived from the regression equtions.
