Abstract:  
A nondestructive method and apparatus for the inspection of impact treated surfaces to predict impact treatment process variables which acquires a multi-dimensional map of an impact treated surface, characterizes the multi-dimensional map to develop surface texture parameters, and develops relationships between the surface texture parameters and the impact treatment process variables.
