Enhancement of Material Properties by Infiltration of Powder Metal Part: Formulation and Method of Application Thereof

摘要

Infiltration compositions comprising chromium and at least about 80% copper. The infiltration compositions may further comprise iron, zinc, manganese, antimony and/or lubricants. Also, methods for infiltrating powder metal parts comprising contacting a powder metal part with the infiltration composition comprising chromium and at least about 80% copper and heating the powder metal part and infiltration composition to a temperature sufficient to melt the infiltration composition and allow the infiltration composition to infiltrate through pores in the powder metal part.
