Our range of services

Laser coating or laser cladding can be used to locally functionalize metallic components. In this process, an edge layer of typically 0.1 to 2 mm is applied to the component. The coating material employed is either powder or wire, or applied in advance as a tape. The complete melting of the filler results in a dense layer with optimal adhesion to the substrate. The most common application is for the wear protection, e.g. of tools, but also corrosion protection or high temperature resistance can be specifically improved. Common hard alloys based on cobalt, nickel and iron are used with and without the addition of hard materials. But also specifically adapted materials can be applied.

The range of services the group offers includes feasibility studies on customer-specific tasks, coating material development for specific applications, the integration of laser coating into production processes as well as consultancy in the design of processes and plants.
