| abstract |
The invention relates to a cylinder and/or a roller and to a method for producing and/or for the maintenance of a cylinder and/or roller. A metal layer (8, 9, 10) is applied, at least in parts, to the outer surface (2) of the cylinder (1, 1'') and/or the roller (1'). Said metal layer (8, 9, 10) has a ductile metallic matrix (4) having embedded urea particles (5). The invention also relates to a device (11) for controlling the wear and tear of a cylinder (1, 1'') and/or roller (1'), the surfaces (2') of which are subjected to wear and tear. The method for producing the cylinder and/or roller, the cylinder and/or roller according to the invention, and the device for controlling wear and tear, allow the maintenance, costs and labour of the cylinder and/or roller to be reduced. |
