Abstract: The invention relates to a spray powder for the production of a Cermet coating on a doctor blade surface, wherein the spray powder includes a mixture of a metal powder and a hard material powder, wherein at least 90 percent of the granules of the metal powder are smaller than 63 ?m, and preferably smaller than 48 ?m, and at least 90 percent of the granules of the hard material powder are smaller than 2 ?m.

Abstract: A blade for doctoring a moving surface or for sizing or creping a fibrous material web produced or finished in a web machine, for example in a paper, board or tissue machine, includes at least one fiber optic waveguide arranged on a surface of the blade or embedded in the material of the blade. The at least one fiber optic waveguide includes a fiber core and a fiber cladding. The at least one fiber optic waveguide further includes at least one fiber Bragg grating.
