Abstract
The presented article is devoted to the effect of borided surface layers on tool steel 19 541 and sintered carbides of type M1 and M2. The article describes the method of boriding sintered carbides and Cr-Mo-V steel. The aim of this work is to analyse knowledge about the boridation of steels. It focuses on the technological prerequisites for the use of boridation in the production process of forming tools in order to increase resistance to frictional, abrasive and adhesive wear. Boriding technology took place at 900°C for 240 minutes. A thick boride layer, hard 1092 HV10, 60 μm thick, was formed on the steel sample. A 5 μm thick layer with a hardness of 1290 (M1) and 1378 (M2) was formed on the sintered carbides. An increase in microhardness of more than 700 HVM was measured for carbide M1 and almost 1500 HVM for M2. The increase in hardness is due to the formation of dispersed cobalt borides Co2B for M1 and CoB for M2.
