摘要
本文提出了一种改善白口铸铁综合机械性能的方法——变质处理和热处理。通过机械性能的测试发现:变质处理后的试样其冲击韧性是未处理试样的两倍多,热处理后的机械性能也大大改善。以上处理的试样经磨损试验,得到了磨损率和机械性能的一些关系。
The improvement of white cast iron integrated mechanical property by inoculation and heat treatment is suggested.Results of the mechanical prop- erty tests carried out show that the impact strength of specimen treated by inoculation is more than double that of untreated specimen,and the mecha- nical property of heat-treated specimen is also much improved.Wear and tear tests of the treated specimen are made by Brinell wear test machine,and the relation between wear rate and mechanical property is set up.
