A method is for cutting machining of a workpiece using a laser beam. The method includes (a) directing the focused laser beam onto a surface of the workpiece for a formation of a kerf; and (b) removing a material exclusively by ablation. The laser beam has a power density in a focal point of at least 1*107 W/cm. The laser beam has a feed speed taking account of an absorption capability of the material to be removed of at least 150 m/min up to a maximum of 1200 m/min.

The present invention relates to hard coating of ferrous metal substrates using a laser beam with diamond particles in a metal matrix produced from precursor powders of metals which bond to the diamond particles and to the ferrous substrate. The hard coating is particularly useful for white iron castings for pumps () used in piping tar sand and water mixtures.

A temperable member manufacturable in a low cost and flexible manner to make possible a locally discriminating tempering process. The temperable member is formed from at least two modules joined to each other. At least one of the modules is formed as a one-piece element, and at least another element is a tempering module. The tempering module is formed from plate-shaped elements arranged on top of each other and forming a stepped outer marginal contour. The one-piece element includes a housing which is complementary to the contour. At least one channel is formed inside the tempering module.
