The results of metallographic analysis of high-speed steel R6M5 obtained by powder cladding on an automated complex CLT-Yu-5 with multichannel (48 beams) CO2 laser are presented. It is shown that the phase composition of steel is martensite, 10 % of residual austenite and 2 % of V2C carbides. The microhardness of the deposited metal is 8500...9000 MPa. The results of the conducted research may be useful to manufacturers of bimetallic tools with a working part made of fused high-speed steel.
