TRIBOLOGICAL PROPERTIES OF DUPLEX COATINGS OBTAINED BY SEALING IN SUCCINIC ACID
Journal Title: Tribologia - Year 2009, Vol 227, Issue 5
Abstract
The paper presents the tribological properties of duplex coatings obtained on aluminium alloy EN AW-5251 via hard anodising of aluminium in a multi-component electrolyte and subjected to sealing in succinic acid. Tribological tests were conducted in a couple with a PEEK/BG material in a reciprocating motion at a test stand, T-17, simulating the conditions of cylinder/sealing contact of lubricant-free pneumatic servo-motors. The obtained results show a reduction (to 35%) of the friction coefficient of a sliding couple consisting of a polymer (PEEK/BG material) and an oxide coating, as well as a significant reduction of wear of the polymer tribopartner (to 65%), as a result of the modification of the oxide coating by sealing it for 20 minutes in succinic acid at a temperature of 368 K. The presented research shows that the modifying of oxide coatings via sealing may enhance the operational durability of lubricant-free machines.<br/><br/>
