Surface treatment is used in a wide range of industries to improve the surface properties of a component. Laser cladding is a process where materials are added to the melt pool of the surface of a component in form of powder or wire to create a surface layer with different properties. Laser cladding can be used for the creation or repair of large or complex geometries. In laser surface treatment, large or complex components are rapidly heated and cooled to improve the surface hardness.
