用自制的高精度单摆划痕装置，分别测量了ＴｉＡｌ４Ｖ合金在空气以及０．５ｍｏｌ／ＬＨ２ＳＯ４溶液中于不同腐蚀电位下腐蚀和腐蚀磨损过程中的比能耗，材料流失量，摩擦系数和动态硬度等。
The changes of specific energy consumption, material losses, friction coeffi- cient and dynamic hardness of Ti6A14V during corrosive wear process in 0. 5 mol/L H2S04 solution at different potentials and in air were investigated using a pendulum scratching appa- ratus, the hydrogen contents in scratching tracks was measured with SIMS, and the mor- phologies of scratching tracks were observed by SEM. The results showed that the wear pro- cess induced the hydrogen concentrating at wear subsurface, which decreased the energy con- sumption per unit volume of material loss and facilitated the nucleation and propagation of the surface cracks.
