钛合金由于比强度高和耐蚀性好而在航空航天、石油化工等领域得到广泛的应用。但其表面不耐磨而限制了其更为广泛的应用。将经过激光处理和未经激光处理的TB5合金放置在一种特殊固体介质进行渗氧处理,通过研究炉的加热条件和前处理过程,分析其对TB5合金的显微组织和硬度的影响。此外,在相同实验条件下与TA4合金进行了比较。实验结果表明,经激光处理和未经激光处理的钛合金在相同温度和氧化时间下进行渗氧处理均获得了一层强化层,且经激光处理后的试样在进行渗氧处理后渗氧层的厚度和表面硬度值明显要高于未经激光处理的试样。在相同实验条件下,TA4合金比TB5合金更容易渗氧。
Titanium alloy has been widely used in aerospace, petrochemical and other fields due to its high specific strength and good corrosion resistance. However, its surface is not wear-resistant and limits its more widespread application. The laser-treated and non-laser-treated TB5 alloy was placed on a special solid medium for oxygen treatment. The effects of heating conditions and pretreatment process on the microstructure and hardness of TB5 alloy were analyzed. In addition, compared with TA4 alloy under the same experimental conditions. The experimental results show that the laser treatment and non-laser treatment of titanium alloy at the same temperature and oxidation time oxygen treatment were obtained a layer of strengthening layer, and the laser-treated samples after the oxygen treatment oxygen Layer thickness and surface hardness values were significantly higher than those without laser treatment. Under the same experimental conditions, TA4 alloy is easier to oxygenate than TB5 alloy.
