Even distribution of a coating

A metalized surface is a common requirement for ceramic parts. Common coatings are Gold, Graphite and Platinum.  A common method of applying such coatings was to use a resonate liquid which when fired, left a thin layer of gold, (or other metal on the ceramic surface).  

A major technical challenge was to develop a process to atomize and evenly distribute coatings.    Control and consistency of coating thicknesses were primary requirements.  

The first phase of this project was the R&D of the spray head technology.  A number of methods were considered.  The final selection was incorporated into a machine that remained in production and operated dependably for over 15 years.
