I guess what I was the help I needed was what to look for in regards to each process step:
Heat Treating - What are some of the potential root causes?
Copper Plate / Stop Off - What are some of the potential root causes?
Copper Plating Strip - What are some of the potential root causes...
Meteng:
After heat treatment, the copper plate is removed chemically. Our metallurgical lab has confirmed it is SCC and the location of the fracture was around the circumference of the gear. Their was no evidence of SCC or damage to the mating part. The failure was found in service...
What are some key contributors of SCC on carburized 9310 material?
Process background:
Copper Plated as a stop off
Carburized to .015" TCD
Copper is stripped after the heat treat
