Abstract:
The peculiarities of the phase transformations by a pulse laser hardening in a solid state and from a melt, leading to the higher wear-and-heat-resistance of a laser influence zones, were studied for the cobaltic high-speed steel with a different initial structural-and-phase composition, created by the preliminary volume heat-treatment. The practical conclusions of this article show that laser treatment of a cutting instrument must be done with a short melting of the working edges surface for a guarantee of its wear-resistance higher increase. An instrument work after the laser hardening must be realized on heightened cutting speeds for the lowering of efficiency of weakening processes on the initial stage of its working edges heat.
Keywords:
high-speed steels, structural-and-phase composition, volume heat-treatment, laser hardening, wear-and-heat-resistance of cutting instrument.
