On the structure, thermal and tribotechnical properties of the antifriction infiltrated materials based on iron and copper

Abstract

This paper describes some properties of the Fe-based materials infiltrated with tin bronze and Cu-based materials infiltrated with tin. It was shown that due to the increased thermal conductivity infiltrated materials based on iron and copper have high tribotechnical properties. With an increase the thermal conductivity the coefficient of friction is reduced, and the seizure pressure increases in infiltrated iron-based materials as a result of the increase in the copper phase and certainty of its morphology, and in copper materials through the creation of a gradient structure in content of tin.
