Abstract:
A method for making a part from particulates of ferrous material comprising the steps of:providing a quantity of particulate ferrous material;electroplating a metallurgical layer of from greater than about 0 wt % to about 50 wt % of ductile metal or alloy onto each of said particulates to produce coated particulates;consolidating the coated particulates in the shape of a part to make a part having a green density greater than that of a part made by consolidating the particulate ferrous material;heating said part at a sufficient temperature for a sufficient time to diffuse said metallurgical layer of metal or alloy into the particulate ferrous material, said temperature being less than the sintering temperature of said ferrous material, said temperature being less than the sintering temperature of said ferrous material.
