DETERMINATION OF THE ABRASIVE WEAR RATE FOR THE LOW FRICTION COATINGS USING BALL-CRATERING METHOD
Journal Title: Tribologia - Year 2009, Vol 224, Issue 2
Abstract
In this paper, a micro-scale abrasive wear tests was used to calculate of the abrasive wear rate Kc for the coatings TiN, WC/C and MoS2/Ti. SiC particles, with a mean size diameter of 4 μm, were mixed with distilled water (concentration of 20% v/v). The experimental results indicated the following: – This method is very important from the technological point of view because of low values of standard deviation obtained for the diameters of the craters in the substrate and coatings. – It is possible to measure the abrasive wear rate for the substrate Ks and the abrasive wear rate for the coating Kc for different types coatings using this method. – It is possible to compare the wear coefficient of coating Kc for all analysed coatings using ball-cratering method (same wear test parameters).<br/><br/>

THE REASONS FOR DIFFERENCES IN WEAR VOLUME IN POLYESTER OILS AND POLYESTER OILS/REFRIGERANT MIXTURES
Friction pairs of refrigeration compressors are always lubricated by an oil/refrigerant mixture. This paper presents the results of wear amounts after tribological tests of different polyester oils from the same viscosit...
TRIBOLOGICAL PROPERTIES OF HIGH CARBON STEELS IN AN AS-CAST STATE AND AFTER PLASTIC DEFORMATION
The aim of the study was to conduct dry sliding tests on the designed hypereutectoid steels with the controlled contents increase of carbon, chromium, and manganese. Chromium and manganese were used to balance the change...
TESTING THE EFFECTIVENESS OF ANTISCUFFING FLUIDS USED DURING THE TRANSPORT OF BOTTLES ON CONVEYORS
During transport on conveyor, glass bottle surfaces are damaged on their surface of contact. Wear traces in the form of rings arise. Counteracting this process involves, in particular, the use of antiscuffing fluids. The...
