Powder lubricant wins patent
Apex Advanced Technologies  of Cleveland, Ohio, has been awarded a US patent for a new solid metal powder lubricant for use in the compacting process.
The company’s president, Dennis Hammond, was one of the collaborators around two years ago in the development of what may emerge as a new class of powders – activated nanopowders.

The U.S. Patent & Trademark Office said: "The present invention provides a lubricant system in the pressing of powders to form a part. The lubricant system is a solid at ambient conditions. However, upon application of pressure during the pressing of the metal parts, the lubricant system forms a liquid phase along the walls of cavity in which the powder is being pressed." US Patent No. 7,183,242  was assigned on February 27.
