Introduction to Powder Metallurgy
Powder metallurgy (PM) has been called a lost art. Long before furnaces were developed that could approach the melting point of metal, PM principles were used. This article provides an overview of the major historical developments of various methods of platinum powder production. The development of production methods took place in various phases starting from prehistoric time, post-war period, to recent and commercial period. The article discusses the powder metallurgy of platinum, as well as the commercial and post-war developments of PM. Literature and trade associations are also discussed.
This article reviews various segments of the powder metallurgy (PM) process from powder production and powder processing through the characterization of the materials and their properties. It covers the processing methods for consolidating metal powders including options for processing to full density. The article outlines the freeform fabrication process, also known as additive manufacturing and describes finishing operations of PM parts. It concludes with information on the applications of PM parts.
