ABSTRACT:
An infiltrant product composition is disclosed for impregnating an iron powder compact. The infiltrant alleviates typical problems associated with use of infiltrating materials, including partial dissolution of iron base matrix by the infiltrant with consequent severe erosion, oxidizing or reducing effects of furnace atmospheres on infiltrant yield, and incompatible characteristics of infiltrant with the iron base matrix. The preferred infiltrant composition is by weight about 98.25% copper alloy and 1.75% carbonyl type iron powder. An additional 0.05% of aluminum to reduce residual formation and minimize residual adherence and 0.5% of a conventional lubricant based on the copper-iron mixture are added. The infiltrant is in a dry, compactible form.
