Abstract
Hexagonal boron nitride (h-BN) material was added to a nickel aluminum alloy (Ni–Al), which was deposited as plasma spray coatings, and the resultant enhanced tribological properties of these coatings were investigated. The microstructures of the coatings were analyzed using a scanning electron microscope (SEM) to monitor the morphologies of both the powders and the coatings. After wear testing, the surface morphologies of the scratched coatings were analyzed using an SEM to monitor the fracture mode of the coatings. The results of this study indicate that the addition of h-BN material to Ni–Al results in coatings with enhanced tribological properties.
