Abstract (en)

[origin: WO2008119600A1] The invention relates to a coating of a mechanically stressed surface of a component (1) made at least partially of a tempered steel, produced by the application of a sol-gel layer (7,8), conversion of the sol-gel layer into a gel, and the subsequent sintering of the layer by means of a laser (4), wherein the laser output is controlled such that the tempered steel of the component is not heated above the annealing temperature. In this manner, the object is attained of creating a simple, cost-effective, and environmentally friendly coating method with which electrically insulating oxide-ceramic layers may be formed.
