METHOD FOR PRODUCING A PLAIN BEARING ANTIFRICTION LAYER

摘要

The invention relates to foundry engineering, more specifically to producing an antifriction layer of a plain bearing by casting babbitt into a bearing shell or backing and is applicable to the manufacture and renewal of plain bearings. The invention is aimed at improving the quality of a plain bearing antifriction layer. A method for producing an antifriction layer of a plain bearing including: casting babbitt into a bearing shell or backing and forcedly cooling the babbitt at a speed providing structural uniformity of the antifriction layer, mainly by cooling babbitt on the cast-in layer side, characterized in that said casting of babbitt into a bearing shell or backing produces a semifinished antifriction layer which is subjected to plastic deformation by means of a punch under superplasticity conditions to produce an antifriction layer, the bearing shell or backing being used as a die.
