Talk to an engineerService overview
Laser cladding technology uses laser to coat high-performance metal materials on the surface of the part base. Due to the extremely high energy of the laser beam, the cladding material and the base material are melted at the same time. After rapid cooling, a perfect metallurgical bonding coating is formed, thereby significantly improving the surface of the part. It has the characteristics of wear resistance, corrosion resistance, high temperature resistance, oxidation resistance, etc., so as to achieve the purpose of surface modification or repair, which not only meets the requirements for the specific performance of the material surface, but also saves a lot of precious elements.
Laser additive remanufacturing is a technical behavior based on laser cladding technology (laser cladding repair) to restore the appearance and mechanical properties of parts that have failed in service or misprocessed parts. At present, laser additive remanufacturing technology has been widely used in precision equipment and parts, gas turbines, steel metallurgy, rail transportation, industrial support, agricultural support, and other fields.
service advantages
Master the core technology of laser material thermal processing
The component has high forming accuracy
Based on the molten pool image sensing and ImageSense® closed-loop system, the molten pool size (±0.25 mm) and cladding height (±0.10 mm) can be accurately controlled.
Excellent fatigue resistance
With DynamicHeat® and metal powder material technology, the thermal stress of formed parts can be minimized and their fatigue resistance can be maximized.
Longer coating lifespan
The metallurgical bond strength between the laser cladding coating and the base material is several times higher than that of the electroplated coating, resulting in a longer coating lifespan.

Characteristics of ultra-high-speed cladding and traditional cladding processes
Huirui’s ultra-high-speed cladding technology is at the forefront of the industry
Technical features:
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 parts, so as to achieve the goal of surface modification or repair and meet customer requirements for specific surface properties of materials.
In the conventional laser cladding process, laser energy is mainly used to melt the base material to form a molten pool. The powder is injected into the molten pool, melted, and then solidified to form a protective coating.
Process features:
Ultra-high-speed cladding coating cladding speed is faster: Ultra-high-speed cladding technology can clad the surface coating of the substrate two orders of magnitude faster than traditional laser cladding technology. High-efficiency coatings of more than 1.5 square meters/hour can reduce the cost of laser cladding to the same cost as hard chrome plating.
The thickness of ultra-high-speed cladding coating is thicker: the thickness of ultra-high-speed cladding coating is at least 120 μm and can reach up to 1000 μm, while the electroplating coating is a physical combination, and the coating thickness is generally 20-60 μm; laser coating and substrate The bonding of materials is a metallurgical bonding, the bonding strength is several times higher than that of electroplated coating, and the coating life is longer.
Ultra-high-speed cladding is not easy to cause deformation or cracking of the base material: Ultra-high-speed cladding causes smaller heat-affected zones and thermal stresses on the base material than traditional cladding processes, and is less likely to cause deformation and cracking.
