Manufacturing Processes for FeCoNiCr Powder

フェCoNiCr powder, a versatile material with unique properties, can be produced through various manufacturing methods. The choice of process depends on factors such as desired particle size, purity, and cost. Here are some common techniques:

機械的合金化

• A mixture of elemental powders is subjected to intense mechanical deformation and attrition.
• The powders are placed in a ball mill with hard grinding media. The impact and friction between the powders and the media cause them to mix and break down into smaller particles.
• Simple equipment, low cost, and ability to produce powders with a wide range of compositions.
• Can introduce impurities from the grinding media, and the process can be time-consuming.

ガス噴霧

• Molten metal is sprayed into a high-velocity gas stream, causing it to break down into droplets that solidify into particles.
• The molten metal is poured into a nozzle and atomized by a gas such as nitrogen, argon, or helium. The particles are then collected and cooled.
• Produces spherical particles with a narrow size distribution, high purity, and excellent flowability.
• Requires specialized equipment and can be energy-intensive.

プラズマ・スプレー

• A plasma torch is used to heat a powder feedstock to a high temperature, melting it and depositing it onto a substrate.
• The powder is injected into a plasma torch, which is then directed at the substrate. The molten particles solidify on the substrate, forming a coating.
• Can produce thick coatings with complex geometries and can be used to deposit a variety of materials.
• Can produce porous coatings and may require post-processing to improve their properties.

Electroplating and Electrodeposition

• A metal or alloy is deposited onto a substrate from a solution containing its ions.
• The substrate is placed in a solution containing the desired metal ions, and an electric current is applied. The ions are reduced at the cathode, forming a coating on the substrate.
• Can produce very thin, uniform coatings with precise control over thickness and composition.
• Limited to producing coatings on conductive substrates.
