with TiN-CrN films tested decreases greatly compared to that of the bare metal. Key words: arc-glow plasma depositing; magnesium alloy AZ91D; TiN-CrN multi-layer film; adhesion strength; friction... the wear resistance of magnesium alloy AZ91D. Under the condition of dry sliding, the specimen coated with TiN-CrN multi-layer film has a lower friction coefficient than that of bare AZ91D. References......

Null 包大杰1 (1.上海柴油机厂,上海,200432) 摘要: 问:何谓钢铁中全碳量(总碳量)和游离碳?答:碳在钢,铁中主要以化合状态和游离状态存在.在钢中主要以铁的碳化物如:Fe3C,Fe23C6等以及与某些合金元素的碳化物如:Mn3C,WC,TiC,MoC,VC,Cr3C2,Cr6C2等形式存在,统称为化合碳,钢中很少有游离碳.在铁中碳除以化合碳存在外,还以游离状态(石墨碳)存在,而且是主要形式.但是在白口铁中则多以碳化铁(Fe3C)形式存在. [全文内容正在添加中] ......
