Abstract:The surface high speed steel and its high properties 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 analyzed in detail by TEM.ª

 

Key words: double glow plasma surface alloying; solution heat treatment; carburizing; high speed steel
