Abstract
In some examples, a material may be subject to shot peening of a relatively long duration to improve cavitation erosion resistance of the material. For example, the material surface may be shot peened to cause grain reduction and an increase in hardness to a depth of 60 μm or more, while the surface remains relatively smooth. As one example, the method may include treating a surface of austenitic stainless steel by impacting the surface with shot media for a treatment duration of 15 to 40 minutes at a shot peening intensity corresponding to an Almen strip type A intensity of 5A to 10A.
