Conclusions
-
1.
TCP of blanks made from the bimetal steel-wear-resistant iron does allow one to eliminate the defects of the overheated steel base, i.e., the Widmanstäten structure, and large grain practically without changing the structure of the coating layer whose microhardnes is slightly higher than it was in the initial condition.
-
2.
Use of TCP for the treatment of the bimetal steel-wear-resistant iron permits one to increase the serviceability and life of parts for which these bimetal composites are used.
