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 temperatures range, high wetting capability for WC and various substrates.
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 wear and 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, which is produced 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 material. It is a transition layer material that sits between the base and coatings of ceramics, soft metallics and other materials. It is a transition layer material that can improve both the base’s ability to resist gas erosion at high temperatures, as well as the coating. The bond strength.
This thermal spray powder is composed of a nickel-chromium base with iron added. Its resistance to oxidation at high temperatures is slightly less than that of the nickel-chromium. Other properties are the same. 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 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. The aluminum will also oxidize at the same time and create 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 for corrosion resistance, wear resistance, and especially sliding wear resistant parts such as wire drawing rollers, cams and plungers in rolling mills.
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 if its storage time exceeds three months. (120°C, 2 hours of heat preservation).
