Overview Of The Process med roterande elektrod

The rotating electrode process (REP) is a sophisticated method used in the production of high-quality metal powders. This technique involves melting a metal electrode that rotates rapidly in an inert atmosphere, leading to the production of fine, spherical metal powders. These powders are critical in various industries, including aerospace, automotive, and electronics, due to their superior properties and uniformity.

Key Details of the Rotating Electrode Process

The REP is known for its ability to produce powders with specific particle size distributions and high purity. The process typically utilizes metals such as titanium, nickel, and stainless steel. This method is particularly valued for its efficiency in producing powders for additive manufacturing and powder metallurgy applications.
