| Abstract: |
| The work aims to study sliding wear resistance and wear mechanism of WC-10Co4Cr coating. WC-10Co4Cr metal ceramic coating was prepared on 0Cr13Ni5Mo stainless steel by using HVOF. Phase composition and microstructure of the coating were characterized. The micro-hardness, bond strength, porosity, sliding wear at 560 r/min and 1120 r/min were tested. Average micro-hardness was 1325Hv0.2, bond strength 72 MPa, porosity 0.76%, weight loss ratio 1:138.36 after continuous wear for 10 h at 560 r/min, 1:127.44 after continuous wear for 10 h at 1120 r/min. At the beginning of sliding wear, wear failure mechanism of the coating is mainly present as abrasive wear. With the increase of sliding velocity, the wear failure mechanism is mainly present as fatigue wear. |
