POWDER METALLURGY
Metal particles are crushed in crushing m/c for final powder. 3. Electrolysis Process By choosing suitable conditions such as electrolytic composition and concentration temp and current density many metals can be deposited in a spungy or powdered state further processing is required which yields high purity and high density powders.
