Conclusions

  1. 1.

    A decrease in molebdenum content occurs in the surface layers during the quench heating of a tool formed from high-speed tungsten-molybdenum steel in a barium chloride salt bath after the required heating time, while a decrease in the tungsten content takes place with more prolonged hold times.

  2. 2.

    It is possible to reduce or completely eliminate loss of alloying elements in the surface layers of a high-speed-steel tool during heat treatment when magnesium fluoride in combination with silicon carbide additives is used as a rectifier.
