Ti-6AI-4V合金在模拟空间环境下的摩擦学性能
Tribological Properties of Ti-6AI-4V in Simulated Space Environments
摘要
Abstract
The tribological property and mechanism of Ti-6A1-4V alloy space harsh environment were investigated on the space tribological test system which was made by the State Key Laboratory of Solid Lubrication (LSL). The simulated space environment including ultrahigh vacuum, atomic oxygen atmosphere and ultraviolet irradiation has been built up in the test system. The worn surface morphologies, compositions of both Ti-6A1-4V and its counterpart GCrl5 steel balls were characterized with scan electron microscopy (SEM) and energy dispersive spectroscopy (EDS). The surface composition of titanium after atomic oxygen irradiation was analyzed by X-ray photonelectron spectroscopy (XPS). It has been found that Ti-6A1-4V sliding against GCr15 steel balls under ordinary atmospheric environment is dominated by abrasive and adhesive wear; while server adhesive wear, abrasive wear and plastic deformation under the ultrahigh vacuum, atomic oxygen and ultraviolet irradiation environments; Ti- 6A1-4V was oxidized after atomic oxygen irradiation.关键词
