PVD coatings different color each batch!
PVD coatings different color each batch!
(OP)
Hi there, I have PVD coating done by a company in Ontario that boasts full process control for repeatable thickness and properties, yet every time I get a batch of parts done by them the color is slightly different. What could cause this variation? ZrN coatings are sometimes a rich lemon yellow (what I want) and other times pale silvery/gold (not good). Is there something I can suggest to them to get more consistency? I need both wear resistance and color quality. Thanks for any help.

all conditions should always be the same.
What kind of batch are they using?

Thanks for trying to help me understand this process more fully. A few years into the research and development of my product and I still don't fully understand the variables.
