摘要： Improved coating blades are disclosed, as well as processes for manufacturing such blades. The inventive blades have an intermediate edge deposit (3) effective to reduce heat transfer from a wear resistant top deposit (2) to the blade substrate (1) . 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 process for the manufacture of a coating or doctoring blade comprising a band of steel or other form-stable material and a wear-resistant polymer coating applied on said band along a longitudinal edge section thereof subjected to wear, said process comprising the following steps: (a) providing continuous relative movement between said band and an application and treatment station; (b) continuously applying at said station a fast-curing polymer composition along said edge section; (c) allowing the applied composition to spread out so as to reach the very extreme of said edge section and then to cure to form an elastic and tacky-free coating; and, optionally (d) post-curing the coating at an increased temperature; as an alternative to such process there can be used a blade of double width compared to said first band and continuously supplying a fast-curing composition along a longitudinal central section of double width compared to said edge section and longitudinally cutting said second band along the middle of the coated central section thereof to form two tip-coated blades; and a coating or doctoring blade prepared by such process.

摘要： A coating blade for the application of coating color onto a travelling web, the blade having an edge section with a profile conformed to the surface of the web when in engagement therewith. The coating blade is characterized by a sacrificial layer covering at least the edge section and protecting the underlying edge section during the web loading phase. The invention also relates to a method of preparing a coating blade by applying a film forming solution onto an edge section of the blade, and allowing the solution to dry so as to form a solid film.
