大型钛及钛合金精铸件污染层研究

Research on Pollution Layer of Large Casting Titanium and Titanium Alloy

对于钛精密铸造而言,铸件表面污染层的大小直接影响铸件质量,但目前对污染层的研究较少,并对其去除方法论述较少。本文通过实验,明确了污染层的主要成份,并对其除去方法进行了探讨,实验结果显示铸件完全达到了各项标准的要求。

For the precision casting of titanium,the surface of the casting has a direct impact on the quality of the casting.There are few studies on the pollution layer,and the method of removing it is less.In this paper,the main components of the contaminated layer were determined through experiments,and the removal methods were discussed.The experimental results showed that the castings have met the requirements of the standards.
