摘要
用自蔓延铝热离心法对球墨铸铁管内表面进行了重熔处理。结果表明，在球墨铸铁管内表面形成了０３ｍｍ厚的白口组织，其显微硬度为６７２ＨＶ，远远高于其铁素体基体。
he inner surface of the ductile cast iron pipe was
remelted by the SHS centrifugalthermit process.The experimental results showed that a
03mm white iron layer,which microhardness was about 672HV,was formed in the SHS CT
process.The corrsion resistance of the based pipe wont be reduced for this process.
