摘要
分析了高频、中频感应熔涂Ni60涂层的显微组织。结果表明,高频感应熔涂Ni60涂层与基体形成了良好的冶金结合,在涂层与基体之间存在明显的扩散转移层。高频感应熔涂涂层组织均匀细致,有丰富的增强耐磨性的硬质相。相比之下,中频感应熔涂涂层基本上均为针状组织,形成贫铬区倾向较大。
The microstructure of Ni60 coating by high frequency induction cladding and medium frequency induction cladding was analyzed The results show that the metallurgical combination is formed between Ni60 coating and base,while diffusion and transfer coat can be observed obviously The microstructure of Ni60 by high frequency induction cladding is even and detailed There are a lot of hardness phases which can enhance abrasionperformance By contrast, The Ni60 coating by medium frequency induction cladding is mainly composed of the needleshape microstructure and has a greater inclination to form the zone of lacking chromium
