Abstract
A coating process for the manufacture of cleaning blades is used where a hardened material coating is electro-deposited onto a carbon steel cleaning blade. The coating process is selected to provided a microporous surface. The pores thus produced are enlarged. The surface is sealed with sub-micron size particles of fluorocarbons, heat treated to create a smooth, slippery surface, while the hardened metal coating provides wear resistance to friction encountered during cleaning operation.
