摘要： A highly reactive conversion coating chemistry is used during CAVF processing of high hardness steel alloys such as AMS 6509 and AMS 6517 steel alloys. This chemistry produces a hard, thin, black conversion coating that is not fully rubbed off by the media during the CAVF process. Distressed material regions on the surface of the alloys are not susceptible to forming the conversion coating and remain white. Visual inspection for the presence of such regions is facilitated.
