Due to its principles, CS prevents degradation of the WC grains when exposed to high temperatures during the deposition by HVOF or APS, producing a hard and dense coating with unaltered WC grains. This study evaluates the performance of CS WC-17Co coatings under erosion by solid particles and abrasion by third body testing, as well as sliding wear behavior. For water-flow exposed surfaces, e.g., piping or hydro turbines, measuring the cavitation and water jet erosion is essential, and minimizing the cavitation phenomena has been a challenge for scholars and design teams. This work presents the effect of different water characteristics (surface tension) on the CS WC-17Co coatings performance. It is noted that reducing this liquid property improves the coating life.

We find that results (in particular dependence on amplitude of roughness, and on friction coefficient) are qualitatively similar to the original Persson and coworkers’ theory, but may differ substantially quantitatively. As the assumption of a constant fatigue threshold may be incorrect for short cracks, both fatigue limit and fatigue threshold are made dependent of crack size, using the Murakami formulation as one of the possible alternatives. This makes wear rate be sensitive to the fine scale details of the roughness spectrum, which has an effect on increasing wear rate and small particles emission.
