摘要：

The results of an investigation of the structure and microhardness of P18 high-speed steel under combined plasma and heat treatment are given. The layer modified by compression plasma flows is found to consist of two regions containing solid solutions based on bcc and fcc iron, these regions having cellular and lamellar structures. Subsequent annealing makes it possible to recover carbides dissolved under the effect of a plasma flow. Combined treatment yields formation of a more uniform and dispersed structure which cannot be obtained using conventional thermal treatment.
