Laser powder cladding –
highly finished surfaces

Modern parts are subjected to particularly heavy loads. There is accordingly a growing demand for components with increased resistance to wear. In many cases, however, this resistance is only necessary at the stressed points and nowhere else. The original properties of the remaining material must not be altered.

With laser powder cladding, the laser beam melts a thin surface layer simultaneously with a powdered additive material, forming a metallurgical bond between the two. The resulting pore-free layer exhibits minimal blending and has only a small heat affected zone.

The required surface properties can be achieved using different powder qualities. Wear protection can be applied in this way and the method is additionally suited for repairs or design changes.

The aim is to obtain an optimum surface with the specified technical characteristics. For this purpose, the movement unit must be capable of applying the individual tracks exactly adjacent to one another via the contour.

These two processes – laser powder cladding and laser hardening – can also be combined on one machine to significantly enhance its performance.
