Tribology has been and will continue to be one of the most significant subjects due its prevalence in practically every part our lives [...]

Friction and wear behavior exists between hoisting ropes that are wound around the drums of a multi-layer winding hoist. It decreases the service life of ropes and threatens mine safety. In this research, a series of experiments were conducted using a self-made test rig to study the effects of the strand lay direction and crossing angle on the winding rope's tribological behavior. Results show ...

Abstract Abrasive wear can have a detrimental effect on machinery, especially in the mining and construction industries. To prolong machinery lifetime cut down energy consumption, thorough understanding of abrasive is essential: surface topography measurement interpretation (including form, waviness, roughness) are vitally important. However, potentially crucial influence intricacies tribologic...

In his seminal text Friction and Wear of Materials, Ernest Rabinowicz defines wear as “the removal of material from solid surfaces as a result of mechanical action” [1]. The wear problem is incredibly important from an economic perspective; in the manufacturing industry, cost is in direct proportion to the frequency with which a particular component must be replaced. In many applications, worn ...

OBJECTIVE The main objective of this study was to evaluate the wear characteristics of fiber-reinforced dental composites. Variables under investigation include the fiber weight percent added to the matrix as well as fiber length. METHODS Dental specimens with glass fiber content of 2, 5.1, 5.7, and 7.6 wt% with fiber length of either 1.5 or 3 mm, were prepared by mixing an activated dental r...
