Click here for a detailed list of materials. Wide variety of coating materials such as Stellite 6, Stellite 12, Inconel 625, Inconel 718, Stainless steel 431, Stainless steel 316 and many more can be deposited on the shafts based on the functional requirements. Unlike hard chrome, the coating exhibits strong metallurgical bonding with 99.99 % dense coatings and do not chip or peel. The amount of material required for cleanup is often substantially less than the conventional shaft cladding techniques. In contrast, conventional welding techniques such as Plasma Transferred Arc require multiple layers to achieve similar properties.ĭue to the fast cooling rates and fine grain microstructure, deposited clad material results in high hardness. This coating material is not diluted with the substrate material, resulting in a high-quality deposit that exhibits the required properties. The process involves melting the powder material onto the surface of the shaft to form a coating. Right, shaft machined to the toleranceĪnother significant benefit of laser cladding is its ability to produce consistent hardness with minimal dilution. Picture: Left, Laser cladding on precision machine tool shaft. There is no need to straighten or machine the shafts to get them back to dimensional tolerances. This focused heat input prevents the surrounding material from being overheated and avoids warping or cracking of the shaft. This is because the laser cladding process uses a highly focused beam that delivers a concentrated amount of energy to a very small area. One of the key advantages of shaft laser cladding is the minimal heat input into the part, resulting in minimal to no distortion in most cases. This process uses a high-powered laser beam to melt and fuse a layer of metal powder onto the surface of the shaft, thereby restoring its shape, size, and functional properties. especially those that have suffered from wear and tear or corrosion. Shaft laser cladding is a highly effective process for the repair and refurbishment of industrial machinery components such as precision tools, motor shafts, centrifuge components etc.
