Abstract
A method for providing an abrasive layer on the surface of a turbine engine component is described. The method includes application of several layers of nickel; one layer includes abrasive particulates. The layer has good bond strength and has a thin cross section, thereby minimizing any effect on the fatigue strength of the component.
