20100326270 | PROCESS FOR ROUGHENING METAL SURFACES - A method of roughening metal surfaces of a workpiece such as a cylinder bore of an internal combustion engine to improve the adhesion of layers thermally sprayed thereon. Uniform grooves are formed in the surface and ridges are arranged between the grooves. The grooves may be formed by a process such as turning, drilling, milling or rolling. The ridges are plastically deformed in order to form undercuts in the grooves, with the degree of plastic deformation of the ridges varying regularly in the longitudinal direction of the grooves. Local deformations are produced in the ridge, and these bring about regular undercuts in the groove. This makes it possible to produce the undercuts in identical dimensions with little effort. Furthermore, since the groove is now not completely constricted by undercuts, it can be filled more effectively with spraying material. | 12-30-2010 |
20110030663 | METHOD FOR PREPARING A SURFACE FOR APPLYING A THERMALLY SPRAYED LAYER - A method for preparing a surface, previously roughed in a mechanical manner and comprising sharp-edged ridges and recesses, on metal workpieces for applying a thermally sprayed layer. The roughened layer is machined by hammer or percussion brushes with a rapidly rotating hammer or percussion brush having a plurality of resilient percussion wires that are oriented in a radially outward manner, such that the edges of the ridges are broken in order to improve the adhesion of the subsequently applied thermally sprayed layer or are at least curved forming rear sections. The brush rotates at a high rotational speed of approximately 3000-6000 rotations per minute and is displaced laterally with its rotational axis being at a parallel distance that remains constant in relation to the surface of the workpiece such that percussion wires distributed on the periphery of the brush impact with the ends thereof of the surface areas adjacent to the workpiece at an oblique angle that is less than 90° in rapid succession. The brush consists of an essentially cylindrical rotationally symmetrical brush body having a plurality of support bars that are parallel to the axis, that are mounted on the periphery of the brush between front-sided brush disks. | 02-10-2011 |
20120058363 | COATED LIGHTWEIGHT METAL DISK - The invention relates to a coated lightweight metal disk, in particular a brake disk, comprising a support disk made of a thermally resistant lightweight metal alloy, and a heat-insulating friction layer formed from a metal alloy that includes nanocrystals. The friction layer can be applied directly to the support disk without adding an insulating intermediate layer. Because of the thermally insulating effect of the friction layer, only a moderate amount of heat is transferred to the support disk. | 03-08-2012 |
20130129939 | PROCESS FOR REPAIRING A CYLINDER RUNNING SURFACE BY MEANS OF PLASMA SPRAYING PROCESSES - A method of repairing an inner surface of a cylinder liner housed in an engine block. Material is removed from the inner surface to produce a reduced-thickness region, the reduced-thickness region extending axially relative to the cylinder and stopping short of an end of the liner to leave a region of original diameter between the reduced thickness region and the end of the liner. The surface the reduced-thickness region is then roughened, for example by hammer brushing. A plasma coating is applied to the reduced-thickness region and to at least a portion of the region of original diameter. The coating is then finish-machined to produce a uniform internal diameter equal to an original internal diameter of the region of original diameter prior to the application of the coating. | 05-23-2013 |
20130199490 | REPAIRED ENGINE BLOCK AND REPAIR METHOD - A block for an internal combustion engine having at least one coated cylinder bore, which has a chamfer at a sealing surface with respect to a cylinder head, wherein the chamfer is a curved chamfer. | 08-08-2013 |
20130284140 | METHOD FOR ROUGHENING AND COATING A SURFACE - A method for roughening and thermally coating a surface, in particular a cylinder running surface of an internal combustion engine, the roughening being the preparation of the surface for the thermal coating of the surface with a coating. The method is characterized in that different roughening profiles are introduced into the surface during the roughening and the coating has different properties distributed over the surface. This allows the coating or spraying process during the later thermal coating to be carried out with substantially constant spraying parameters. The different properties of the coating, such as hardness, porosity, machinability, chemical composition, oxidation and adhesion, are then obtained just on the basis of the differently roughened surface. | 10-31-2013 |
