Home-made impact wear tester was designed to investigate the effects of wear impacting angle and temperature on the coating. Ni60 coating was deposited and re-melted on the surface of compacted iron through flame spraying. The wear mass and morphology were studied in different impacting angles of 30°, 45° and 60° at different temperatures of room temperature, 200 and 400. The wear mechanisms were discussed. It was found that the wear mass increased with the increase of the testing temperature. In the impacting angle range of 30o to 45o, the wear mass decreased with the increase of the impacting angle. In the impacting angle range of 45o to 60o, the wear mass increased with the increase of the impacting angle. At room temperature, abrasive grain wear and adhesive wear took effects. At the temperature of 400, oxidation wear, abrasive grain wear and adhesive wear took effects together. The wear forms were similar in different impacting angles. |
