Microstructure and high temperature properties of nitride enhanced titanium aluminum alloy layer
摘要
在国内，对于钛合金激光表面复合合金化对高温性能的影响的研究一直在进行着，事实上，中国钛合金的研究和工业化生产起步并不晚，2001年，国家科研所开始着手研究钛合金激光表面复合合金化对高温性能的影响这个课题，国家于2001年已把钛列入了科学技术发展十二年规划的第十六个项目。2000年在抚顺铝厂实现了海绵钛的半工业化生产。2003年在北京有色金属加工厂钛车间熔铸车间铸造出了钛锭并加工成钛材。到20世纪60年代中期实现了工业化，并建立了遵义钛厂和宝鸡有色金属加工厂。直到今天，航空航天工业融入是钛及钛合金的主要应用领域，其他领域如建筑、医药、能源、海洋和近海、体育休闲以及交通运输等的应用需求也正日益增加。
对于钛合金激光表面复合合金化对高温性能的影响的研究一直是一个长期且不断深入的话题，需要几代人几十代人的努力才能取得一定的研究成功，目前，国内正在加大对钛合金激光表面复合合金化对高温性能的影响这个课题的投入，争取在2026年在这个研究领域取得显著的成绩。 [资料来源：http://Doc163.com]

Abstract
In China, the research on the effect of titanium alloy laser surface alloying on the properties of high temperature has been carried on. In fact, the research and industrialization production of titanium alloy is not too late. In 2001, the National Research Institute began to study the influence of the high temperature performance of titanium alloy laser surface composite. In 2000 to achieve a semi industrialized production of sponge titanium in Fushun aluminum plant. In the 2003 workshop of titanium casting workshop of Beijing nonferrous metal processing factory casting a titanium ingot and processed into titanium. By mid 1960s, the industrialization was realized, and the Zunyi titanium plant and Baoji nonferrous metal processing factory were established. Until today, the aerospace industry integration is the main application areas of titanium and titanium alloys, other areas such as construction, medicine, energy, marine and offshore, sports leisure and transportation, etc.The study of the effect of laser surface alloying on high temperature performance of titanium alloy has been a long and continuous hot topic.
It is needed to study the effect of the metal on the high temperature performance of titanium alloy laser surface.This graduation design topic comes from the research topic which the teacher in the research, mainly aimed at the characteristic that the titanium alloy high temperature difference, the titanium alloy carries on the alloy modification processing.
The structure of the alloy layer, the high temperature oxidation resistance and the tribological properties of the alloy were systematically analyzed, and the alloy coating with high temperature properties was prepared.
Keywords：Titanium aluminium alloy; high temperature performance; research; microstructure
