OPTIMISATION OF TEST PARAMETERS INFLUENCING THE DRY FRICTION OF W-DLC COATED ELEMENTS

Journal Title: Tribologia - Year 2013, Vol 252, Issue 6

Abstract

The application of thin hard coatings, such as the DLC type, acquires growing importance in the area of machine elements working under conditions of friction. Due to mechanical properties, the thin hard coatings provide the increase in the durability of coated elements, the resistance to abrasion, and protection against corrosion. The structure of the coatings influences the tribological properties of friction joints by lowering the motion resistance. The extension of the area of coating application is connected with the development in the field of tribological research. One of the main issues of research quality is the spread of results, especially important while considering the friction coefficient and wear resistance of friction joints with coated elements. This paper presents the application of an optimization method for the selection of test parameters for the tribological research by means of a nanotribometer. The tested friction joint consisted of steel ball rubbing against a rotating steel disc with WC/C coating under conditions of low loads. The determination of optimal test parameters for the lowest possible results spreads were conducted according to the Taguchi approach. As a result of the performed research, the differentiation of analysed test parameters in the manner of influence on results spreads was determined. The optimal test parameter values are indicated in the study. The general effects of the conducted investigation are the recommendations for tests conduction by means of nanotribometer.
