Plasma transferred arc spraying of tungsten carbide coatings can significantly increase the service life of machines and components subject to wear. This paper assesses the effect of such coatings in oil sand processing equipment. It describes the development and testing of the layers used and explains that the extraction and processing of oil sands necessitate continuous testing and ongoing improvement in both materials and processing techniques. Paper includes a German-language abstract.
