Weld-overlay coatings erosion

Erosion resistance of materials is very dependent on the erosion conditions, the effects of which are dominated by a number of variables including particle size, shape, composition, and velocity angle of incidence and temperature. Unlike wear properties, the erosion rate of weld-overlay coatings generally increases with increasing hardness (Fig. 8). However, the erosion resistance of weld-overlay alloys depends on whether the...
