Abstract

See full text

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.
