Laser Cladding

Laser Cladding

Laser cladding is a process in which material is deposited on the surface of a part or work piece. Various high power lasers can be utilized for cladding, such as CO2, Nd:YAG, diode, and fiber. The laser cladding process is ideally suited for and is often used to create an entirely new surface, as well as to repair damaged or worn surfaces (remanufacturing). It is even possible to create functionally graded coatings where the material composition of the coating can be changed on the fly, resulting in material properties tailored to particular areas of components. For example, the construction equipment industry applies this technology to their products because it increases wear resistance, keeping equipment in service longer.

How Laser Cladding Works

Typically, a powder is introduced to a substrate, and then a laser beam is used to melt the powder onto the substrate. The clad material may also be introduced in a wire form. The process produces a 100% dense metallurgical bond deposit with minimal dilution of the base material for enhanced corrosion, abrasion, and wear resistance when used to laser clad metals.

Advantages

There are significant advantages of laser cladding over standard or traditional weld cladding or hard facing.

  • Can produce denser coatings with little or no porosity, finer surface finishes, more consistent layer thicknesses, and more precise clad placement, than traditional thermal spray techniques.
  • Is inherently a low heat input process, resulting in low dilution, fine microstructures, small heat affected zones (HAZ), and low distortion.
  • Helps reduce processing time.
  • In specific applications, laser cladding may restore parts to their original dimensions without secondary operations.
  • Improves upon the materials inherent susceptibility to corrosion, wear and oxidation.
