摘要： Improved coating blades are disclosed, as well as processes for manufacturing such blades. The inventive blades have an intermediate edge deposit effective to reduce heat transfer from a wear resistant top deposit to the blade substrate. In one embodiment, the intermediate layer is comprised of NiCr, possibly with embedded oxide particles. Suitably, the intermediate layer and the top deposit are applied by an HVOF process. It is also envisaged that the intermediate layer may be deposited by plasma spraying. The intermediate layer may comprise stabilized zirconia.

摘要： A doctor blade for direct contact with a ceramic roll surface. The doctor blade includes a strip of metallic carrier material, which, along one edge section is provided with a ceramic coating. The ceramic coating on the blade has a hardness ranging from approximately 850 to 950 microvickers, thereby substantially increasing wear resistance of the blade without substantially increasing wear on the ceramic roll surface for which the blade is adapted for use.

摘要： The wiping cylinder of a steel engraving printing machine is coated with a plurality of thin plastic layers over a rubber base layer. When the wiping cylinder is to be cleaned with an organic solvent, the plastic coatings are of a thermoplastic synthetic resin that is soluble in water but not in organic solvents, for example polyvinyl alcohol that is partially saponified and contains acetyl groups. When the wiping cylinder is to be cleaned by an aqueous solution, the coatings are of a synthetic resin such as polyvinyl chloride that is not soluble in water. The thin plastic layers are applied successively by means of a doctor blade assuring smoothness, uniformity and exact thickness of the layers, and each layer is hardened before the next is applied.

摘要： A doctor blade (5, 7) for contact with an anilox roller (15) comprises a flat, elongate base element having a thickness of less than about 0.3 mm, which, along a longitudinal region of the doctor blade adapted for contact with said anilox roller, is provided with a coating (43). The coating comprises a metal matrix and at least about 65% by weight of one or more ceramic(s). The coating comprises 0 to 65% by weight of chromium carbide. An inking arrangement comprises an anilox roller and a doctor blade. A doctor blade is used in flexographic printing.
