TRIBOLOGICAL WEAR OF A COMPOSITE–COMPOSITE SYSTEM IN THE PRESENCE OF DIFFERENT ABRASIVE MATERIALS
Journal Title: Tribologia - Year 2012, Vol 244, Issue 4
Abstract
The article presents the results of abrasive wear resistance of metal–polymer thermo- and chemosetting composites in composite–composite tribological system. To make the comparison, some friction experiments were performed using a steel–bearing alloy system. During the research, two kinds of regenerative chemically setting composites were used. The cross-linking agents used were amine compounds with different chemical structure and reactivity (such as triethylenetetramine and adduct of aliphatic and aromatic amines). These cross-linking agents made it possible to obtain composites with very different mechanical properties. Electrocorundum and silica of defined chemical and granulometric composition were adopted as abrasive material. Chemosetting metal–polymer composites were applied to a steel roller and machined to the desired size to cooperate with a bronze block and metal-polymer composite based on thermosetting phenol- -formaldehyde resin. The friction tests were performed using a T-07 block- -on-ring tester in the presence of the selected abrasive material. Tribological tests were conducted at a speed of 0.1 m/s and 1 MPa pressure, without any lubricant. A high resistance to abrasive wear of the tested systems was proved, which means they can be used for machine element regeneration that are running in an abrasive environment.

MICRO-IMPACT CRACKING OF TRIBOLOGICAL COATINGS
The stress field in the coating/substrate system causes combined effects on both the coating and substrate materials due to cyclic loads. The consequence is the initiation and propagation of fatigue cracks leading to a l...
