The needle-like and network carbides in as-cast high carbon wear-resistant manganese steels will be nodularized and dispersed,by a large majority,in austenite aider modifying treatment with Mg system agents.The impact toughness of the steels is significantly improved and the hardness is also increased to a certain extent.As a result,the steels can be used in as-casted state without any heat treatment and their wear resistance can be greatly enhanced.

中国腐蚀与防护学报

扩散处理对黄铜上电镀铝层结构与性能的影响牛洪军,宋国泰(吉林工业大学长春130025)(吉林省电力试验研究所长春130021)1前言与热浸镀铝和固体粉末渗铝相比,熔盐电镀铝具有操作温度低、工艺易控制、镀层表面质量好等优点.但是,熔盐电镀铝常常会形成粗大树枝晶,出现镀层疏松和显微裂纹t‘-’],使镀层的耐蚀性下降.本工作以黄铜为基体材料,采用AICI。-NaCI熔盐为镀浴,并通过低温扩散处理,?...
