What is nickel-based powder alloy? Nickel-based powders are widely used for the self-fluxing series. It offers excellent corrosion resistance, heat resistant, oxidation resistance as well as low stress wear resistance. Low melting temperature, large solid-liquid range, good wetting ability of WC and substrates.
The spray-welding layer has outstanding properties of self-fluxing and wettability. The spray-welding layer has the properties of 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 powder thermal spray, like 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. The base metal is used as a transition layer material for 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, which makes it ideal for repairing corrosion resistant workpieces 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, corrosion resistant and wear-resistant. It can be used as an anti-corrosion treatment for shafts and cylinders.
The thermal spray powder of nickel-aluminum is used to coat surfaces. It is made up of fine aluminum and nickel particles. 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. At the same moment, some of the aluminum oxidizes, releasing 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 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 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).
