TRIBOLOGICAL RESEARCH OF MULTICOMPONENT COMPOSITE ON A POLYOXYMETHYLENE BASE DURING FRICTION WITH STEEL
Journal Title: Tribologia - Year 2009, Vol 225, Issue 3
Abstract
In the article, the results of the research concerning the influence of the unitary p stress, sliding speeds v, and the parameter of the roughness Ra, steel encounters on elements of tribologic properties of multicomponent composite on a polyoxymethylene base (POM) were described. The tested composite contained 60% vol. POM + 12% vol. of PTFE powder + 20% vol. of powder of bronze + 8% vol. of glass filler (50% glass fibres and 50% glass microballs). Tribological examinations were carrying out on tribometer of the "pin on disk" type in changeable conditions of a forced process of friction, technically dry on steel. The initial values in testing were assumed: intensity of the linear wear Ih, the rate of the friction μ and the final temperature Tt of tested friction pairs. In the completion of these tests, a rotatable plan of the experiment was used on 5 levels for 3 of the variables. On the basis of test results, the multidimensional functions of the regression (about the second-degree figure of the polynomial) were determined, which enabled drawing the tribologic characteristics up in the form of spatial and contour graphs. Conducted examinations showed the significant influence of the value of assumed initial values on tribologic properties of the studied sliding pair. Elaborated tribologic characteristics can be helpful in optimal geometrical features used in the shaping of sliding joints using the studied association and in determining their border level of exploitation<br/><br/>
