laser cladding technology

Laser coating is an advanced industrial coating technology which can be used to improve the corrosion, wear and high temperature properties of various components and equipment. During the laser coating process, the coating powder is melted on the surface of the work piece to be treated. The energy needed is supplied by a laser beam. During the process, a small and controlled amount of base material is melted resulting high strength metallurgical bonding. The characteristics of laser coating are a completely dense and solid structure and small dilution between the base material and coating substance. The material properties of the coating are similar to those of the corresponding wrought material. The resulting coating thicknesses are usually between 0,5 3,0 mm. The material changes caused by the heat load are minimal. Laser coating can be applied for most coating-base material combinations.
