In the process of coal mine production, coal mine machinery bears strong load force. Parts such as gears and shafts will stop running due to wear and corrosion failure under high-speed operation and long-term high temperature conditions, whether they are returned to the factory for maintenance or scrapped., will cause huge economic losses.
Laser cladding technology can use specific powder according to the material and hardness of gears and shafts to repair the worn part, restore the original size, improve wear resistance, corrosion resistance and other properties, and has good economic benefits.
