TiCN Cermet Composite Coating Prepared By Reaction Nitrogen Arc Welding Cladding Process
A TiCN cermet composite coating was fabricated on 45# steel substrate by reaction nitrogen arc welding cladding technique.The mixture powder of titanium and graphite was preplaced onto the 45# steel substrate after intensive mixing by star ball-mill and gluing with starch binder.The microstructures and phase of the coatings, interracial behavior between coatings and the substrate were investigated by scanning electronic microscope, X-ray diffractometer.The microhardness distribution of the coating section, frictional coefficient, abrasion loss and wearing surface morphology were investigated by microhardness tester, abrasion machine and scanning electronic microscope.The results show that an excellent bonding between the coatings and the 45# steel substrate is ensured by the strong metallurgical interface and phase of the coatings are mainly composed of TiCN.The highest microhardness of the coatings reaches HV0.5810, which is about 3 times more than that of the 45# steel substrate.The anti-abrasive test results show the coating has better anti-abrasive performance than the 45# steel substrate.
