WEAR RESISTANCE OF CONSTRUCTIONAL MATERIALS IN COOPERATION WITH THE OXIDE COATING
Journal Title: Tribologia - Year 2011, Vol 238, Issue 4
Abstract
This article presents the results of tribological tests, stereometric tests, and surface morphology tests carried out with steel structural materials prepared according to ANSI: 304, 316, 52100 and ceramic structural materials like WC (tungsten carbide) and SI3N4 (silicon nitride) used for co-operation with aluminum oxide coating. The aim of the study was to determine the usefulness of selected materials for co-operation with anodic oxide coating under dry friction conditions. This paper is a continuation of a research on the co-operation of APT with plastics. The oxide coating was formed on EN AW-5251 aluminum alloy by the electrochemical method in a ternary electrolyte system. Tribological tests were carried out using the T-01 tester with a ball-on-disc friction system and under dry friction conditions and for rotational motion. Other test parameters were accepted in accordance to guidelines of the VAMAS program. Test results established that the selected materials behaved in various manners during tribological cooperation with oxide coating. Steel materials varied greatly in frictional wear intensity and other tribological characteristics. The research also revealed that stainless steels are not suitable materials for cooperation with anodic hard coating under dry friction conditions. For other materials, smaller friction wear intensities were obtained.<br/><br/>
