Scraper blade, useful in coating unit of machine for producing and/or finishing fibrous web e.g. paper or cardboard web, comprises base substrate, and layers having quasi-continuous or stepwise changing material composition

The scraper blade (1) comprises a base substrate (2) and layers provided on base substrate. The layers have a quasi-continuous or stepwise changing material composition. The change takes place in a binder system of layers and/or in a concentration of hard materials. A first layer (3.1) is formed on the substrate. A second layer (3.2) is formed on the first layer. A third layer (3.3) is formed on the second layer. A transition in the second layer takes place between a material composition of the first layer and the material composition of the third layer.

The layers have thickness of 50-300 mu m. Eine Schaberklinge (1) zur Verwendung in einer Maschine zur Herstellung und/oder Veredelung einer Faserstoffbahn, insbesondere in einem Streichaggregat einer solchen Maschine, umfasst ein Grundsubstrat (2) und darauf angeordnet eine Mehrzahl von Schichten (3), wobei die Mehrzahl von Schichten eine sich quasi-kontinuierlich oder stufenweise ändernde Materialzusammensetzung aufweist.
