Title:
IMPROVED METALLURGICAL COMPOSITIONS CONTAINING BINDING AGENT/LUBRICANT AND PROCESS FOR PREPARING SAME
Document Type and Number:
WIPO Patent Application WO2001030521
Kind Code:
B1
Abstract:
Improved methods for coating particulate materials at low shear conditions and preferably below the melting point of the coating material are provided. In one aspect, metallurgical compositions are provided that contain a metal-based powder bound to and alloying powder or powders by way of a low melting polymer or wax binding agent, which is preferably polyethylene. The binding agent is blended with the metal-based an alloying powders at elevated temperatures preferably below the melting point of the binding agent. The bonded metallurgical composition can be used in compaction processes to manufacture compacted parts that can be sintered to impart strength.
