Mainly used for surfacing repair of chemical equipment and various mechanical equipment wear parts. For example, metallurgical machinery and cemented carbide composite rods are commonly known as mace rods. They are a type of nail crusher with cemented carbide broken particles YG grade. The cemented carbide particles of various sizes and sizes are made by physical crushing and sintered and wrapped with CuNiZn welding material. A reinforcing material. Has a certain strength, good plasticity, impact resistance, wear resistance.
The method of surfacing operation is correct, and the sign of satisfactory quality of the surfacing layer is: after cooling, the surface of the surfacing layer is shiny golden yellow, the carcass alloy of the surfacing layer and the base metal are well combined, and the alloy particles are closely arranged and uniform. Firm welding is embedded in the carcass metal.
The signs of overheating or overburning are: after cooling, the carcass metal is red, and the alloy particles are exposed on the black surface. The consequence is that the working performance of the alloy particles is impaired, which affects the service life.
The signs of insufficient heating are: after cooling, it is matte silver gray, the carcass alloy and the base metal are poorly combined, and the entire surfacing layer may fall off when the tool after surfacing is in operation.
