| description | Heat resistance steel type of H13 is used for the aircraft structure parts whose working temperature is 400~500℃ Moreover, it is required to wear resistance for the parts in some special service environments In order to solve the problem of wear failure in hot work dies during service, a low power laser type of Nd：YAG was used to cladding SiC ceramics on the surface of H13 steel The macroscopic feature, microstructures and compositions were observed by the metalloscope, scanning electron microscope and energy depressive spectroscopy Experimental results indicated that that the cross sections of the cladding sample were markedly divisional (Clad Zone, Fusion zone, Heataffected zone, Substrate Zone) The microstructure of cladding layer is nondirectional and compact, without obvious crack and porosity and with good performance The homogeneous microstructure of bonding layer is dendrite and equiaxed grain with small size, and the massive columnar crystal grew from the bond line of H13 steel substrate to fusion zone The wear resistance of laser cladding ceramics on heat resistance steel surface is analyzedBesides, a through crack appeared after the scanning speed up to 40mm/min、60mm/min on the cladding layer as the hard and brittle characteristic of SiC ceramics and the difference of thermal expansion coefficient between SiC ceramics and substrate; The above research results provide some theoretical support for improving the surface wear resistance of aircraft heatresistant parts. |
