结果表明:该涂层与基体呈冶金结合,内部组织均匀细密无缺陷,是固溶了大量Cr的-γFe相与高硬度析出相的共晶组织;其在海水中的耐蚀性远高于0Cr18Ni9Ti不锈钢,两者在海水中均表现为点蚀。
The results show that some defects such as metallic inclusion,unmerited heat treatment process and so on,conduce the existence of bulky acicular silicon and herringbone(α+Si) two-phase eutectic structure,which reduces the mechanical properties.
结果表明,轮辋材质成分夹杂、热处理工艺不当等缺陷造成组织中存在大量的粗针状硅和鱼骨状(α+Si)两相共晶组织,该组织降低其力学性能是造成轮辋脆性断裂失效的主要原因。
