Bearing having nickel-tin-copper barrier layer

The heavy-duty performance of a lead-tin babbitt-lined, copper-lead based journal bearing is improved by a novel trimetallic barrier layer (16, 18, 20) interposed between the lead-tin babbitt (10) and copper-lead (12) layers. The trimetallic barrier layer contains the elements nickel, tin and copper...

Zusammenfassung:	The heavy-duty performance of a lead-tin babbitt-lined, copper-lead based journal bearing is improved by a novel trimetallic barrier layer (16, 18, 20) interposed between the lead-tin babbitt (10) and copper-lead (12) layers. The trimetallic barrier layer contains the elements nickel, tin and copper in suitable proportions. In a preferred embodiment, the barrier layer consists of layers of nickel (16), tin (18) and copper (20) metals successively plated over the copper-lead base (12).
