I. Cutters will face complex working conditions during the working process. For example, common agricultural machinery cutting tools need to cut and turn the soil, which contains various sand and gravel particles, which will cause serious abrasive wear on the surface of the cutting tools. When harvesting crops (such as wheat, rice, etc.), the cutting tools of the harvester not only have to face the friction of plant stems, but also resist the corrosion that may be caused by plant sap. Moreover, during high-speed operation, the cutting tools also bear a large impact force. Laser cladding can play a good role in repairing the above problems. By selecting wear-resistant materials for cladding, such as high-hardness tungsten carbide (WC) based alloy powder, the wear resistance of the tool surface can be effectively enhanced. Taking the plow as an example, after laser cladding treatment, its wear resistance in soil can be significantly improved, extending the service life of the tool, reducing the frequency of tool replacement, and thus improving agricultural production efficiency.
II. We recommend a 3000W laser cladding machine with a robot for cutters cladding. Of course, the laser solution will be adjusted according to the type, size, and weight of the jobs.
Advantages
I. Laser cladding has a complete metallurgical bond with the substrate, which means it does not peel or shatter like plasma or thermal spray coatings.
II. The porosity is small or non-existent, and laser cladding can be applied with a 100% completely dense coating.
III. There is little or no thermal deformation, and the heat input of laser cladding is less than 20%.
IV. Extremely low dilution, with better metallurgical properties and higher corrosion and wear resistance.
V. Thinner cladding layers can be applied due to lower dilution rates, which can significantly reduce the cost of composite materials.
VI. The cladding process is stable, and the automatic control of the process provides excellent parameter control, resulting in excellent process stability and reliable, repeatable results.
