Laser Cladding Service


Laser cladding is a coating process that uses a laser beam to melt a thin layer of coating material and substrate to form a porous, porous and crack-free coating that adheres perfectly to the substrate. Although this process can be used for large area coverage by overlapping individual tracks, it is the ability to protect a wide range of materials that can be deposited and localized areas that make laser cladding particularly suitable for tailoring surface properties to local service requirements. A new perspective on surface engineering. Laser cladding is widely used to protect materials from wear, corrosion and oxidation, and to repair components and tools. Other applications with significant potential are materials development and synthesis and fabrication of freeform near-net geometries. Examples of recent work are presented and discussed.

The cladding method is a bulk coating deposition technique. We find a wide range of applications to improve performance and extend the service life of end products by providing laser coatings that are resistant to abrasion, erosion, corrosion, slip wear and thermal barriers. Coating development by laser cladding is quite challenging because many process control parameters are involved. About 30 sets of process parameters are related to material deposition and quality control of laser coatings. Sufficient research and investigations have already been conducted and still ongoing to improve the surface properties of several engineering components using laser cladding methods. Review has shown that identifying the cause of defects and problems in laser cladding and suggesting solutions is rarely found in the public literature.

In this study, measures to mitigate the defects and problems of laser cladding are first presented along with a comprehensive review with the aim of being useful in the application of cladding in the coatings industry. Second, we performed a troubleshooting of laser cladding for the ease of material deposition and improved coating quality. Problems such as material deposition, surface cracking and porosity have been identified and reduced experimentally.
