Abstract:
A method for coating an orifice plate with a material that is non-wetting to a selected material, comprising:providing a plate defining at least one orifice defined by orifice walls therein, the plate having a front surface and providing a transfer surface formed of non-wetting material; positioning the transfer surface adjacent the plate, with a spacer therebetween, the spacer constructed to provide an open space for fluid communication between the transfer surface and the surface of the plate adjacent the orifice; heating the transfer surface to a temperature effective to vaporize the non-wetting material and permitting the vaporized non-wetting material to coat the surface of the plate adjacent the orifice, the transfer surface spacer and plate constructed and arranged and heated to an effective temperature to coat the surface of the plate adjacent and substantially up to the edge of the orifice, but substantially not the surface of the orifice walls.
