What is nickel based alloy powder? Nickel-based powder is widely used for the self-fluxing series of alloy powders. It offers excellent corrosion resistance, oxidation resistant, heat resistance as well as low stress wear resistance. Low melting temperature, a wide range of solid to liquid temperatures, strong wetting for WC particles and substrates, and simple operation.
The spray-welding layer has outstanding properties of self-fluxing and wettability. The spray-welding layer is characterized by high hardness and corrosion resistance. It also has wear resistance, heat resistance and is resistant to heat. Wet grinding is preferred.

Classification nickel-based alloy powder
Nickel-chromium alloy thermal spray: There are different types of powders for thermal spray, such as the nickel-chromium alloy heat-resistant alloy that is created by adding 20 percent chromium. Nickel-chromium heat resistant alloys do not oxidize much at high temperatures and are a good coating material that is resistant to heat, corrosion, and high temperature oxidation. The coating is dense, and adheres well to the base metal. It is the transition material between the base and the coatings of ceramics or soft metals. It is a transition layer material that can improve both the coating and the base material. The bond strength.
Thermo-spray powder made from nickel-chromium and iron: Its high-temperature oxidation resistance, while similar to that of Nickel-chromium Alloys, is slightly inferior. Other properties, however, are the same. Nickel-chromium alloys are similar. Its main advantage is its low cost, making it ideal for corrosion-resistant repairs and as a thermal spray powder transition layer.
(3) Nickel-chromium-boron alloy thermal spray powder: This alloy contains elements such as boron, chromium and carbon, so it has high hardness and moderate toughness. The coating becomes heat resistant, wear resistant, corrosion resistant and wear-resistant. It can be used as an anti-corrosion treatment for shafts and cylinders.
(4) Thermal spraying powder of nickel-aluminum: This powder is used to spray primers and is made up of fine aluminum powder and nickel powder. Thermal spray powder is heated up to 600 degrees Celsius with the flame. A chemical reaction takes place between the nickel and the aluminum that releases heat. As part of the aluminium oxidizes, it produces more heat. Nickel can diffuse into base metal at this temperature, which improves the bonding of the coating. A second feature of the thermal spray powder made of nickel and aluminum is the rough surface that is formed on the coating after spraying. This provides an excellent surface to connect other spray materials. It is an excellent intermediate material because the expansion coefficient of nickel aluminum composite thermal spray is similar to most steels.

Uses for nickel-based alloy Powder
The welding is done with oxygen-acetylene plasma or flame. This material is also used for corrosion protection, repair, and maintenance of wear-resistant components, including sliding wear resistant parts such as wire drawing rollers, cams and plungers.
Precautions:
1. Please adhere to the oxygen-acetylene or plasma spray welding requirements.
2. If you are using medium or small spray welders, then it’s best to use powder with a mesh of -150. When using large spray welders, use powder with a mesh of -150/+320.
3. It is necessary to dry the alloy powder if there is moisture in the powder or the storage time exceeds three months. (120°C, 2 hours of heat preservation).
