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, high oxidation resistance and heat resistance. It also has good impact toughness. Low melting temperature, wide solid-liquid range, high wetting capability for WC particles and substrates, and simple operation.
The spray-welding layer has outstanding properties of self-fluxing and wettability. Spray-welding layer with high hardness and corrosion resistance. It is also resistant to heat and wear. 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 heat resistant alloy that is created by adding 20% chrome to nickel. 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 base and the coating. The bond strength.
This thermal spray powder consists of nickel chromium and iron. Although its high-temperature oxidation resistance may be slightly lower than that of Nickel-chromium Alloys, the other properties of this powder are almost identical to those of Nickel-chromium Alloys. Nickel-chromium alloys are similar. Its main advantage is its low cost, making it ideal for corrosion-resistant repairs and transition layer thermal spray.
(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, corrosion resistant and wear resistant after spraying. It can be used as an anti-corrosion treatment for shafts and cylinders.
(4) Thermal spraying powder of nickel-aluminum: This powder is used as a primer and is composed 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. During the process, some of the aluminum will oxidize as well, creating 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 ideal 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. It’s used to protect and repair corrosion-resistant 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 a medium or small spray gun, it’s best to use powder with a mesh of -150. When using a large spray gun, use powder with 320/150 mesh.
3. It is necessary to dry the alloy powder if there is moisture in the powder or if its storage time exceeds three months. (120°C, 2 hours of heat preservation).
