Self-Fluxing Nickel Alloy Powder 45-90 µm

Understanding Self-Fluxing Nickel Alloy Powders

Self-fluxing nickel alloy powders are formulated with elements like boron and silicon, which act as deoxidizers and fluxing agents during the spray process. As the powder particles melt, these elements form a low-melting-point borosilicate slag that protects the molten metal from oxidation and helps it wet the substrate. This mechanism is critical for achieving the high bond strength and low oxide content that make these coatings suitable for demanding industrial environments.

Typical Applications and Process Compatibility

The 45-90 µm particle size distribution is a versatile cut, commonly specified for both high-velocity oxy-fuel (HVOF) and plasma spray systems. It can also be used in certain flame spray setups. The resulting coatings are typically used to protect components against abrasive wear, erosion, and corrosion at moderate to high temperatures. Common applications include the restoration and protection of shafts, pump sleeves, plungers, and various machine parts in the mining, oil & gas, and general engineering sectors.

Selection and Handling Guidance

Selecting the correct nickel alloy grade requires matching the powder's specific chemistry and hardness to the service conditions of the component. Key factors include the wear mechanism (abrasive, adhesive, or erosive), the operating temperature, and the corrosive environment. For optimal results, the powder should be stored in a cool, dry environment in its original sealed container to prevent moisture absorption and oxidation, which can negatively impact flowability and coating quality.
