What is nickel based alloy powder?
Nickel-based powders are widely used for the self-fluxing series. 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. The spray-welding layer has a high hardness and is resistant to corrosion, wear, heat, and wear. It’s also difficult to cut. Wet grinding is preferred.
Classification nickel-based alloy powder
Nickel-chromium alloy thermal spray: There are different types of powder thermal spray, like nickel-chromium heat resistant alloy powder. This alloy is created by adding 20 percent chromium in nickel. Nickel-chromium heat resistant alloys do not oxidize much at high temperatures and are a good coating material that is resistant to heat and corrosion. The coating is dense, and adheres well to the base material. It is a transition layer between the coatings of ceramics, soft metallics, and other materials. It is a transition layer material that can improve both the coating and the base. The bond strength.
(2) Nickel-chromium and iron alloy thermal powder: This type is made from nickel-chromium and appropriate iron, and has a slightly lower high temperature resistance than nickel chrome alloys. 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. 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. During the same process, a part of the aluminium will also oxidize. This 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 a good surface to connect other spray materials. It is an ideal intermediate material because the expansion coefficient of the nickel-aluminum alloy 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).
