Laser cladding has long been recognized as a technology that combines low cost with a multitude of remarkable advantages. At its core, it has the remarkable ability to apply a layer of high - performance alloy onto the surface of workpieces. This thin yet powerful alloy layer acts as a shield, significantly enhancing the wear resistance, corrosion resistance, and overall durability of the workpieces, thereby substantially extending their service life. 

Laser cladding technology, a highly advanced surface modification technique, can be comprehensively categorized into two primary types according to the powder feeding process: the powder presetting method and the synchronous powder feeding method. Despite sharing similar end - results, the synchronous powder feeding method stands out with several significant advantages. It enables seamless automation control, which is crucial for large - scale industrial production.

Laser cladding technology represents a cutting-edge surface engineering technique. Its principle lies in carefully positioning a chosen coating material onto the surface of the substrate in diverse filler forms. As a high - energy laser beam irradiates the area, not only does the coating material melt, but also a thin layer of the substrate's surface is melted simultaneously.
