SOLID PARTICLE EROSION OF HEAT-TREATED NI80P20

Solid particle erosion of a heat-treated crystalline Ni80P20 alloy is compared to erosion of an amorphous No80P20 a alloy. Experiments were performed at room temperature with angular alumina erodents whose size varied from 42 to 390 mu m, whose incidence angle was between 20 and 90 degrees, and whose velocity was 50 to 100 m s(-1). There was no dif ference in the erosion resistance between the two materials because th e impact process causes the heat-treated Ni80P20 alloy to become amorp hous.
