Influence of Hydrogen Contents of Ti-6Al-4V Alloy on Friction and Wear Mechanism between Titanium Alloy and Cemented Carbide

Abstract:

Ti-6Al-4V alloy was hydrogenated at 800°C by thermohydrogen treatment technology. Sliding friction and wear tests were carried out in a special device assembled on CA6140 turning lathe to investigate the friction and wear mechanism between hydrogenated titanium alloys and WC-Co cemented carbide. The morphological analyses of the worn surface were made by scanning electron microscope (SEM) and the diffusion and chemical reaction behavior of elements were analyzed by X-ray energy dispersive spectrometer (EDS). It was found that the main wear mechanisms of the unhydrogenated alloys were abrasion and adhesion and surface fatigue, while the main wear mechanisms of the hydrogenated alloys were abrasion and adhesion. The main wear mechanisms of the cemented carbide were all serious adhesion and spalling, and the specific wear forms were closed related to hydrogen contents. There are all not the chemical reaction wear and element diffusion wear in the friction region of whether the unhydrogenated alloys or the hydrogenated alloys or cemented carbide.
