【 摘 要 】

The aim of Nickel-Tungsten coatings on the material of carbon steel is to improve the wear resistance of the material. However, with the elevated contact temperature due to friction force in the surface area of sliding may alter the wear resistance of Nickel-Tungsten layers. If the elevated temperature is quite high to reduce the hardness performance of Nickel-Tungsten layers, the layers may be degraded more quickly. In this work, Nickel-Tungsten was deposited on the surface of medium carbon steel in the process of flame powder spray coating with layer thickness of about 0.2 mm. The wear test was conducted using linear reciprocating ball-on-plat with varying surface temperature of about 30°C up to about 250°C. The wear rate and wear mechanism of Nickel-Tungsten layer is investigated.
