Conclusions
-
1.
A relationship was established between the resistance to microplastic deformation and the wear resistance. An increase of the resistance to microplastic deformation resulting from tempering after grinding raises the wear resistance of cutters.
-
2.
The optimal tempering temperature after grinding and sharpening is 350–400°C for steel R18 and 450–500°C for steel R9K10. The elastic limit and resistance to stress relaxation increase by 50%, the wear resistance of steel R18 increasing by 75% and that of R9K10 by 50%.
