The sliding wear behavior of the substrate SS 316 and the WC-Co/NiCrAlYSi coating for varying load and speed conditions has been evaluated using pin on disc apparatus. Results indicated distinguished wear mechanisms for uncoated and WC-Co/NiCrAlYSi coated SS 316 steel specimens, which were ...
WC and Cr3C2 with different metallic binders like Co, Ni and Fe have been studied using different amounts of binder contents with Co and Ni most commonly used. Addition of Cr to the matrix has been found to improve the wear and oxidation resistance of these cermets [8], [10]. The ...
