Laser cladding is a technology that uses high-energy laser beams as heat sources to melt metal powder materials onto the surface of parts, thereby preparing high-performance protective coatings on the surface of parts to improve the surface hardness, wear resistance, corrosion resistance, oxidation resistance, and high temperature resistance of materials.
During the working process, agricultural machinery tools are subjected to the impact and friction of various objects such as sand, soil, and straw for a long time, and the blade part is prone to wear, deformation, and corrosion. Laser cladding technology can be used to prepare high-quality coatings on the surface of agricultural machinery tools to improve the wear resistance and corrosion resistance of agricultural machinery tools, thereby increasing the service life of agricultural machinery tools.
Laser cladding is a complex process of multi-parameter coupling. Parameters such as powder selection, laser power, laser scanning speed, powder feeding speed, and spot diameter are very important to the quality of the cladding layer. Huirui Laser strengthens the tool edge through self-developed cladding technology and clads metal-ceramic composite coatings on the tool surface. The coating and the tool substrate are metallurgically bonded, and the bonding force is greater than 400Mpa.
The service life of the tool after laser strengthening treatment is 5-10 times that of ordinary tools. This not only extends the service life of the tool, but also reduces the number of tool changes and maintenance times, greatly extending the use cycle of agricultural machinery and equipment, reducing operating costs, and achieving obvious comprehensive economic benefits.
Typical applications of laser cladding in other industries
- Laser repair of steel mill rollers, conveyor rollers, and extension rollers
- Coal industry (hydraulic support cylinder cladding)
- Petrochemical industry mud pump sleeve inner hole cladding
- Laser quenching of automotive molds
At present, Huirui-Laser has successfully launched four types of equipment, which can complete workpiece repair and quenching strengthening in a short time with different cladding heads and quenching heads.
- The movable laser cladding equipment is a three-dimensional laser cladding equipment specially developed by our company for problems such as rail wear and on-site repair of large workpieces. It can meet the use requirements of on-site repair in various working conditions.
- Special equipment for high-speed laser cladding has the advantages of high laser power, strong reliability, high processing efficiency, and high powder utilization rate, which can meet the stringent requirements of equipment in complex industrial production environments.
