The application of laser cladding technology in the automotive field is increasingly valued. It melts and solidifies coating materials by precisely controlling the laser beam, thereby forming a high-performance coating layer on the surface of automotive parts. This technology can significantly improve the wear resistance, corrosion resistance, and fatigue resistance of components, and extend the service life of automotive components. Due to the local processing characteristics of laser cladding, it reduces material consumption and has minimal impact on the environment. In addition, this technology can achieve surface modification of complex shapes and difficult to access areas, providing new possibilities for automotive lightweighting and performance improvement. With the continuous improvement of cost-effectiveness and environmental protection requirements in the automotive industry, the application prospects of laser cladding technology in the automotive field will be more extensive.
