| 摘 要： | 采用双志了子渗金属技术，首先在低碳钢表面渗入合金元素钨、钼，然后作固溶处理，使金属间化合物溶于基体中，接着渗碳，使合金层内形成在碍区弥散、均匀、细小的合金碳化物。经淬及回火后的合金层具有高速钢组织及性能。对渗透了金属层渗碳后的组织进行了电子分析

| Abstract: | The surface high speed steel and its high propeties are obtained by surface alloying with W Mo, carburizing, quenching and tempering. W Mo alloy layer is formed by double glow plasma alloying process. To dissolve the intermetallics which precipitated from the matrix of the layer, a solution heat treatment is conducted. The carburized alloyed layer possesses high density of finery and dispersed alloy carbides for the high concentrations of W, Mo and their affinities with carbon. Microstructures of the carburized alloyed layer are analysised in detail by TEM. |
