Abstract (en)
[origin: EP0287023A2] The production of such a sprayed surface on a workpiece is to be improved and a surface layer with a clearly defined roughness is to be provided, with relatively simple handling. For this purpose, a pulverulent material consisting of a mixture of a matrix of Ni, Co and/or Fe base alloy and sintered materials having a grain size distribution of the sintered materials with a maximum fraction between 25 and 150 mu m is sprayed on, the sprayed unsintered layer having a surface roughness in the range of Ra from 10 to 100 mu m with a defined roughness of Ra x x +/- 20 mu m, x being a number from 10 to 100 mu m. The process of the invention is intended to be used for producing the surface of transport rollers or gripper fingers for paper or cardboard manufacture.
