Effects of Pure Water on the Tribological Properties of Self-mated Titanium
The novel method of using continuous variations of the electrical contact resistance and the friction coefficient for monitoring the tribological properties and the wear mechanisms of titanium pairs in air had been applied successfully by the authors.Therefore,this study further investigated the tribological properties and the wear mechanisms of self-mated titanium in pure water.In order to investigate the chemical reactions of titanium sliding against under water lubrication,the continuous variations of electrical contact resistance and friction coefficient were measured.SEM was used to observe the microstructures and of material transfer.The variations of electrical contact resistance were shown to produce clear and strong signals,superior to monitoring continuous friction coefficient variations for the self-mated titanium in pure water.According to the variations of electrical contact resistance,TiO2 was inferred to form at the interfaces of self-mated titanium in pure water.All of the experimental results demonstrated that the water lubrication has great potential for the research.
