Tribological Characteristics of ABC100.30 Alloys During Friction on Structural Steels Without Lubrication.

This work aimed to analyze the properties of the experimental ABC100.30 powder material under friction on various structural steels without the use of a lubricant. Tribological tests were performed at constant load and sliding speed for various sliding distance values. The experiments revealed that the studied powder material had the best tribological properties when in contact with steel grade 20. In this case, the friction process was characterized by low values of volumetric and linear wear of the rubbing bodies, as well as a minimum average friction coefficient. The ABC100.30–steel grade 45 friction pair had the highest friction coefficient values and high linear and volumetric wear values. The friction process on steel 30HGSA was accompanied by the maximum wear of the investigated material; however, it was characterized by low friction coefficient values and minimum amplitude of fluctuations.
