一、前言目前白口铁已发展成为一种十分重要的抗磨材料,其应用范围日益扩大。从白口铁的发展来看,已由普通自口铁,镍硬铸铁,发展到高铬铸铁。英美等国已把高铬铸铁列入国家标准,对其成份,组织性能作了不少研究工作。它是抵抗磨粒磨损的优良材料,但它的Cr、Mo、Ni合金含量很高,并不太适合我国。如何结合我国资源条件,发展白口抗磨铸铁是当务之急。近年来,随着硼对铸铁凝固过程及凝固后组织的影响,和硼在灰口铸铁中的作用的研究的深入,含硼铸铁的研究逐步得到重视。硼系合金白口抗磨铸铁,就是在硼铸铁研究的基础 I. Introduction At present, the white iron has developed into a very important anti-wear material, its growing range of applications. From the development of white iron from the point of view, has been ordinary self-iron, nickel hard cast iron, the development of high-chromium cast iron. Britain and the United States and other countries have high chromium cast iron included in the national standard, its composition, organizational performance made a lot of research work. It is excellent material to resist abrasive wear, but its Cr, Mo, Ni alloy content is very high, not suitable for our country. How to combine the resources of our country and develop the white cast iron is a top priority. In recent years, with the boron on the cast iron solidification process and the organization after solidification, and the role of boron in gray cast iron in-depth study, the research of boron-containing cast iron has been gradually paid attention. Boron alloy white mouth wear-resistant cast iron, is the basis of boron cast iron research
