Abstract
Abstract This disclosure pertains to the method of making a steel-backed sleeve bearing strip wherein copper-tin powder is sintered on the strip and is infiltrated with lead-tin babbitt at a carefully controlled relatively low temperature, which temperature is quickly reduced after infiltration to minimize migration of tin from the babbitt to the copper.
