Hello all,

We work in decorative hard coatings on 3D objects. I
am having two problems:

1. I am seeing some blue color on some portions of the
parts whereas rest of the parts on the turntable look
fine. Any suggestions???

2. Also, some of the parts even do not get any PVD
coating whereas other parts on the same turntable get
PVD coating fine. Any suggestions to solve these two
problems in my Arc Evaporation PVD system. Thanks in
advance.

Gary
