Аннотация

The present paper studies the effect of the laser radiation on geometrical and mechanical characteristics of formed tracks using the powder mixtures based on nickel alloys (60 weight % NiCrBSi) and tungsten carbide (40 weight % WC). It has been found that the mode of laser radiation highly influences the shape and mechanical characteristics (the keyhole mode or thermal-conductivity mode) in respect to the surface of the initial layer of the powder mixture. It is demonstrated that in the clad track at the thermal-conductive mode (the focusing mode Δf = ±20), the uniform distribution of ceramic parts is observed, and the maximal microhardness value is registered. It is found that the clad metal-ceramic structure has 4 - 5 times higher value of microhardness 850.4 HV0.1 than the substrate 178 HV0.1.
