Application of TiAl(CN) Metal Ceramic Coating by Reactive Nitrogen-Arc Cladding on Stubble-Cleaning Cutter

Abstract:

The metal ceramic coating of TiAl (CN) by nitrogen-arc cladding technology was produced on the surface of 45#steel.The phase composition of coating was analyzed with X-ray diffractometer; The bonding state and microstructure were observed with scanning electron microscope; The microhardness was examined and the wear resistance of the metal ceramic coating compared with that of 60Si2Mn steel treated by quenching and tempering was tested by abrasive tester as well. The results indicated that the TiAl (CN) ceramic particle synthesized in-situ is distributed dispersively in the cladding and the size is under 3 um. The excellent bonding between the coating and 45# steel substrate is strengthened by the strong metallurgical interface; the coating is uniform and continuous. The maximum microhardness of cladding is HV_0.21820 and the abrasive performance is better than 60Si2Mn steel treated by quenching and tempering. The simulation test results showed that the cladding is good, and can be used to the repair and remanufacture for wearable parts of stubble-cleaning cutter.
