The Tribological Performance of Hardfaced/ Thermal Sprayed
Abstract. During the coal pulverizing the working parts of the ventilation mill are being worn by the sand particles. For this reason the working parts are usually protected with materials resistant to wear (hardfaced/thermal sprayed coatings). The aim of this study was to evaluate the tribological performance of four different types of
