Coating retention - Molybdenum Oxide
I am trying to source a technique or already proven solution for the retention of Sputtered Molybdenum oxide for use in a photovoltaic vacuum process. Currently the shielding does not retain the coating after approximately 1hour of coating due to the build up and inherent stress of the oxide coating. This is falling back on the magnetron and causing short circuits.
The source is depositing at approximately 100nm/min , and we need to operate for approximately 8hours.
I have tried bead balsting and also fine mesh and both will retian molybdenum however will not retain MoOx. I have been informed that Thermal flame spray may be a suitable technique.
Does anyone have any suggestions/reccomndations of this or any other surface techniques that may assisit in coating retention?

Hi Butchless1

Probably a little out of my depth on this one. If Molybdenum oxide coating is predominantly reliant on mechanical keying for bonding, then a thermal spray coating surface preparation may provide a good base. Along the same line of thinking, a sharp grit blasted surface profile should give a much superior bonding surface than that of bead blasting.
