激光冲击强化改善Ti-6Al-4V合金冲击磨损性能（英文）
|
摘要
采用自制的冲击磨损实验台研究激光冲击强化工艺(LSP)对Ti-6Al-4V合金冲击磨损性能的影响,并对材料强化后的显微组织及力学性能进行分析。通过冲击磨损实验研究样品在不同冲击动能作用下的动能吸收、冲击力、磨损接触时间和磨损机理。实验结果表明,经激光冲击强化后,Ti-6Al-4V合金表面的显微硬度、弹性模量和内部残余压应力等均得到显著提高,其磨损抗性也得到显著改善,且强化能量越高,其改善效果越明显。此外,样品的磨损机理为磨粒磨损、氧化磨损和疲劳剥落。
The effects of laser shock peening(LSP) on the impact wear behavior of Ti-6 Al-4 V alloys were investigated by a homemade impact wear test rig. The microstructure and mechanical properties of the peened samples were studied. During the impact wear test, the energy absorption, impact force, wear contact time and wear mechanism of all the test samples were investigated in terms of the influence of the impact kinetic energy. The results showed that microhardness, elastic modulus and residual compressive stress of the treated samples were markedly improved. The wear resistances of both treated samples were highly improved after LSP, and a higher pulse energy corresponded to a more obvious effect. Besides, the wear in all test samples involved a combination of abrasive and oxidation wear and fatigue spalling.
