Gains in Metallizing Economics through Improved Evaporator Boat Design

Presented by Ramamoorthy Ramasamy, GE Advanced Materials

Historically, vacuum metalizers have faced a tradeoff in boat selections. Three-part boats exhibit better wettability while two-part boats show improved corrosion resistance and life. New technology has been developed which helps overcome this traditional tradeoff, giving a wettable, long-life boat design, and results supporting the improvements will be presented. An analysis of the impact of improved boat design on the economics of operating a metalizing line is discussed.
