AN INFLUENCE OF MOLYBDENUM DISULFIDE CONTENT IN ELECTROLYTE ON TRIBOLOGICAL PROPERTIES OF ANODIC OXIDE COATINGS

The paper presents an estimation of the usefulness modification of anodic oxide coatings (AHC) on aluminium alloys with molybdenum disulfide (MoS2) for the improvement of the tribological properties of Al2O3 coatings. An...

DETERMINATION OF MECHANISMS OF WEAR FOR ROLLING-SLIDING CONTACT IN SELECTED OPERATIONAL CONDITIONS BY MEANS OF SURFACE TOPOGRAPHY AND MES STUDIES

The paper presents the influence of selected operating factors, i.e. load, slip, and wear rate, and surface conditions. The wear mechanism between the cooperating rolling surfaces in the rolling/sliding combination varie...

ANALYSIS OF THE HARDNESS OF A SELECTED GROUP OF CAST IRON BRAKE ROTORS

The paper discusses the problems related to cast iron brake rotors in the context of their hardness, which is one of the fundamental mechanical properties of these components. This property fundamentally determines the r...
