Abstract
This study aimed at finding out a suitable material for sliding bearings used in seawater. We carried out two types of wear experiments: oscillatory sliding type and ball-on-disc type; using phenolic resin, PTFE resin, polyamide (PA) resin and Pb-Cu sintered alloy sliding against SUS304. As a result, PA resin shows high wear resistance and low friction, whereas phenolic and PTFE resin indicates different tribocharacteristics depending on the type of wear experiment. Pb-Cu sintered alloy is an unsuitable material for bearings in seawater because of its high corrosive wear rate and high fiction.
