Abstract
The heavy-duty performance of babbitt-lined, copper-lead based journal bearings is improved by a novel trimetallic barrier layer interposed between the babbitt and copper-lead 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, tin and copper metals successively plated over the copper-lead base.
