摘要

利用金相组织观察,电子探针分析及显微硬度测试等方法研究了在铸钢生产中常用的几种铸型材料及氧化钙对钛铝合金铸锭表面的污染情况.试验结果表明:几种铸型材料对钛铝合金的表面硬化层厚度分别为氧化钙16μm,刚玉60μm,氧化锆130μm,锆英砂130μm,远低于对钛合金的污染层厚度,而且不发生粘砂.

Abstract

The paper studied the contamination of some mold materials usually used for steel casting, including Al2O3, ZrO2, ZrO2·SiO2 and CaO on TiAl castings. The contamination depth of those materials on TiAl castings are CaO 16μm, Al2O3 60μm, ZrO2 130μm and ZrO2·SiO2 130μm respectively. All those values are little than that on Ti castings. The conclusion will promote the development of TiAl intermetallics castings.
