Powder resistant metallurgical composition and perfected segregation resistant containing alloy powder linked to a metal base powder, and, processes to prepare for it, for the manufacture of a compact metal part, and to prepare a coated particle

摘要

"Metallurgical composition resistant to dust and resistant to separation improved containing powder of alloy powder attached to a metal based, and processes for preparing the same.For the manufacture of a compacted metal part, and to prepare a partu00eccula coated.Improved processes for coating particulate materials at low shear conditions and preferably below the melting point of the coating material are provided.In one aspect, are provided with a powder metallurgical compositions that comtu00eam metal based alloy powder or powder of an alloy by means of a binder of wax or polymer of low melting point.It is preferably polyethylene, the bulking agent is mixed with the powder of the alloy and metal based, high temperature, preferably below the melting point of the binder.The composition metal connected can be used in compaction for manufacturing compacted parts that can be sintered to resistance to impact.
