摘要

应用铸件表面合金化的方法，实现了碳钢精铸件表面铸态渗硼。渗层深度可达１．０５ｍｍ，硼相的显微硬度值为８００～１０００ｇ／μｍ２；碳钢精铸件铸态脱碳作为可利用的因素，有助于精铸件铸态渗硼。

Abstract

The technology of boronization is applied on the surface of carbon steel investmentcasting（I.C.）.It is proved that: A boronning depth of about 1. 05mm can be reached. The Vickers hardness of boronic phase is in the range of 800～1 000 g/μm2. Surface decarburization of carbon steel I.C.would be beneficial to boronizing.
