The steady-state erosion rate of electrodeposited amorphous Ni/sub 80/P/sub 20/ by angular alumina particles has been measured as a function of impingement angle from 15/sup 0/--90/sup 0/, particle velocity from 50--100 m/s, and average particle diameter from 40--390 ..mu..m. The erosion rate can be described by a power law in velocity and particle size. The erosion rates in Ni/sub 80/P/sub 20/ were compared to those measured for electrodeposited pure crystalline nickel. For all experimental conditions the erosion rate in the amorphous alloy exceeded that of nickel. The material removal in amorphous Ni/sub 80/P/sub 20/ is attributed to formation of plastic shear bands below the impact areas. For the most energetic particles the erosion leads to the formation of melt, which seems to be a consequence of the localized shear.
