Question:
Is there a coating process where the equipment (to do the coating process) can be bought?
Situation:
We currently use a QPQ (Molten Salt Bath Nitriding) but we have to ship the parts to the processing plant. This type of equipment is approximately $500,000 and carries a good amount of EPA baggage.
We would like to have something above 65 Rc with good corrosion properties (versus bare metal). Additionally, the dimension stability is very tight - we can tolerate almost no part growth whatsoever. Our tolerances are +/-.0005 on a finished part. However, if growth is predictable and repeatable - we can adjust for it.
I have experimented with a boronizing treatment - which might still be the solution, but it appears to cause part growth. The ductile iron, being cast, will move an intolerable amount due to the machining stresses and the high application temperature.
Does anyone know of a comparible coating (like the QPQ) where the equipment could be purchased for on-site processing?
