Abstract
A continuous, pinhole-free thermoplastic polymer coating, which may be a fluoroelastomer, is applied to a porous metal surface in a single coating step by spraying the thermoplastic polymer from a thermal spray gun onto a porous metal surface which is at substantially room temperature to form a semi-fused, highly porous coating. The porous metal surface is then heated to fuse the thermoplastic polymer coating into a well-anchored, continuous film. This method permits the application of a continuous thermoplastic polymer coating with one coating step rather than with the plurality of coating steps currently needed to produce a coating with comparable properties.
