Formation and function of protective tribo-oxide layers on TC11 titanium alloy surface
Dry sliding wear tests and specially designed double sliding wear tests of TC11 titanium alloys were carried out at sliding velocities of 2.68 m/s and 4 m/s by using a MPX-2000 type pin-on-disc wear tester. The phase, composition and morphology of worn surfaces and tribo-layers were analyzed in deta...

| description | Dry sliding wear tests and specially designed double sliding wear tests of TC11 titanium alloys were carried out at sliding velocities of 2.68 m/s and 4 m/s by using a MPX-2000 type pin-on-disc wear tester. The phase, composition and morphology of worn surfaces and tribo-layers were analyzed in detail by X-ray diffractometer, scanning electron microscope and energy dispersive spectrometer. The microhardness distribution from tribo-layers to the matrix was measured by using a digital microhardness tester. The results show that tribo-layers are always found to be formed on the worn surface of TC11 titanium alloy at different sliding rates. The phase, state and property of the tribo-layer vary with the sliding conditions. Tribo-layers can be divided into tribo-oxide layer and no-oxide tribo-layer. Through 4 m/s & 2.68 m/s double sliding wear test, the tribo-oxide layer formed in the dry sliding wear process of TC11 titanium alloy is proved to possess good wear-reducing effect. The wear mechanism of TC11 titanium alloy is delamination wear at 2.68 m/s, and oxidative wear at 4 m/s and 4 m/s & 2.68 m/s. |
