Titanium alloys-despite their high strength to mass ratios, good high temperature stability and fatigue and corrosion resistance-have significant shortcomings that preclude their use in many components subjected to sliding contact: Compared to other materials of similar strengths such as steel, titanium alloys have high rates of wear, high coefficients friction, unacceptably high rate of material transfer and adhesion to the counterface and thus are prone to galling and seizure.

尽管钛合金具有高的强度质量比、良好的高温稳定性以及抗疲劳性和耐腐蚀性，但钛合金具有显著的缺点，这些缺点妨碍了它们在许多滑动接触部件中的使用：与其他类似强度的材料如钢相比，钛合金具有高磨损率，高摩擦系数，不可接受的高材料转移速率和对配合面的粘附，因此易于磨损和卡住。
