| Abstract: | The complex heat treatment process of solid boronizing plus laser surface treatment is applied to get boron eutectic layer for the purpose of lowering the brittleness and improving the wear resistance of thesurfacelayer . The reasonableness of the processing parameters is verified by means of mathematical methods ,and the microstructures of the surface layers of the samples are observed using SEM,optical microscope as well as Fe-B-C equilibrium diagram.The mechanism of formation of the boron eutectic and the behavior of the boronized layer in the course of laser treatment are discussed. |
