摘　　要：通过对TC18钛合金在100～1000℃温度范围内的氧化试验以及力学性能测试试验,研究了其氧化色变化规律,并探讨了氧化色与力学性能的关系。结果表明:经氧化处理后,TC18钛合金表面形成多种不同氧化色,且随氧化温度升高,合金表面颜色逐渐加深,合金力学性能均明显下降。合金表面氧化色与其力学性能存在一定的对应关系:当氧化色为浅绿色即加热温度为650℃时,材料力学性能已不满足TC18钛合金标准力学性能。The variation rule of color of oxidation layer of TC18 titanium alloy and relationship between color of oxidation layer and corresponded mechanical properties were investigated via oxidative test within the temperature range of 100-1000 °C and mechanical property test. The results show that various colors of oxidation layer can be obtained. Mechanical properties of the alloy remarkably decrease and colors of the oxidation layer gradually turn dark with the increasing of oxidizing temperature. The relationship between color of oxidation layer and corresponded mechanical properties of TC18 titanium alloy was determined. When the oxidation color turns to be light green, the mechanical properties of the alloy significantly decrease which can not satisfy well the standard mechanical properties of TC18 titanium alloy.
