Proper Smut Identification and Removal on 4130, 9300
Greg Terrell, Pretreatment Product Manager at Coventya, Inc., had someone contact him recently with this question: We are plating 4130, 9300 and a couple other alloys through cyanide cad and are experiencing random pitting that we cannot trace to current density. The pits do not go to substrate, so we have ruled out the pretreatment. Can you visit and offer a fresh set of eyes?
