摘要:

钛合金具有密度低、比强度高和耐腐蚀性强等优异性能,因而被广泛应用于航空航天中,钛合金使用占比成为衡量航空航天设备是否先进的标准之一。由于该合金硬度低、耐磨性差,因此微动磨损成为钛合金零件失效的重要原因之一。为了提高钛合金的抗微动磨损性能,采用激光熔覆技术在TC4钛合金表面制备涂层。实验结果表明,激光熔覆Ti-Al粉末能改善TC4钛合金硬度和耐磨性能。

关键词: TC4钛合金, 激光熔覆, 抗氧化, 耐磨涂层

Abstract:

Titanium alloys possess excellent properties like low density, high specific strength, and corrosion resistance. So, these alloys are widely used in the aerospace. With the development of aerospace, the usage ratio of such alloys is one of the criteria to measure whether the aerospace equipment is advanced or not. Because these alloys show low hardness and wear resistance, fretting wear becomes an important cause for the failure of titanium alloy parts. To improve the fretting wear resistance, laser cladding was used to produce a coating on the surface of TC4 alloy in this study. The results showed that the hardness and wear resistance of TC4 alloy were improved by laser cladding Ti-Al powder.

Key words: TC4 titanium alloy, laser cladding, antioxidation, wear-resistant coating
