Ultra-high-speed laser cladding technology is mainly used to improve the wear resistance, corrosion resistance, high temperature resistance, and oxidation resistance of the surface of the parts, so as to achieve the goal of surface modification or repair, and meet the requirements for the specific performance of the material surface.
The ultra-high-speed laser pointer cladding technology essentially changes the melting position of the powder, so that the powder meets the laser and melts above the workpiece, and then uniformly coats the surface of the workpiece. Its cladding rate can be as high as 20-200m/min. Due to the low heat input, this technology can be used for surface cladding of heat-sensitive materials, thin-walled and small-sized components, and it can be used for new material combinations, such as aluminum-based materials, Preparation of coatings on titanium-based materials or cast iron materials. Since the surface quality of the coating is significantly higher than that of ordinary laser cladding, it can be applied only by simple grinding or polishing, so material waste and subsequent processing are greatly reduced. Ultra-high-speed laser melting is in terms of cost, efficiency, and thermal impact on parts. Covering has irreplaceable application advantages.
As an incubator of Fraunhofer ILT, it was the first to introduce ultra-high-speed laser cladding technology into the Chinese market, and worked closely with Fraunhofer ILT to upgrade the technical industrialization of ultra-high-speed blue laser pointer cladding, continuously improving the level of technology, and enhancing the functionality of its core components, such as The durability of the powder feeding nozzle, powder feeding accuracy, high powder feeding capacity, powder utilization rate, etc.
Based on the original high-precision coaxial powder feeding nozzle of Fraunhofer ILT, the high-efficiency and high-convergence powder feeding nozzle was officially launched. The powder feeding efficiency can reach more than 5kg/hr, and the powder utilization rate can reach 95%. And its special modular design greatly reduces the cost of use, makes the replacement of worn-out parts extremely simple, and at the same time ensures the repeatability of the process, and the nozzle size can also be flexibly adjusted according to the repair position.
The newly developed ultra-high-speed laser cladding processing head, through a special optical path adjustment system design, realizes the most ideal light-powder interaction in space, making powder melting more stable and energy utilization more efficient. The use of ultra-high-speed laser engraver cladding technology can perfectly solve the problems of coal shearer pick cutter head collapse, cutter head and cutter body wear, etc., improve the service life of the pick, and reduce the cost of use.
