Abstract
An in-situ Ti(CN) particle reinforce composites coating was fabricated on Q235 steel substrate by nitrogen arc shielded welding technique which take the titanium powder and the graphite powder as original material. The microstructures, interracial behavior and phase of the coatings were investigated by scanning electronic microscope, X-ray diffractometer, microhardness tester, abrasion machine. The results show that an excellent bonding between the coatings and carbon steel substrate is ensured by the strong metallurgical interface and phase of the coatings are mainly composed of TiC0.51N0.12.The highest microhardness of the coatings reaches HV0.5810, which is about five times more than that of the base metal .The anti-abrasive test results show the coating has better anti-abrasive performance than base steel.
