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...

This paper develops analytically a statistical model for predicting the material removal in mechanical polishing of material surfaces (MS). The model was based on the statistical theory and the abrasive–MS contact mechanisms. The pad-MS and pad-abrasive-MS interactions in polishing were characterised by contact mechanics. Two types of active abrasive particles in the polishing system were consi...

in the present work, the aa2124/25vol.%mosi2 composite was produced by powder metallurgy technique. the aluminum alloy 2124 powder was produced by gas atomization method and the mosi2 intermetallic particles were produced through combustion synthesis. the aa2124 matrix powder was mechanically blended with 25vol.%mosi2 using a ball milling mixer. the blended powder mixture was encapsulated and t...

It is shown that when modeling a single interaction of an abrasive particle with the surface part in process collision under air (liquid) pressure, it necessary to take into account specifics impact-abrasive wear, separation wear preceded by metal destruction. In schematization contact during blasting, some commonality shot blasting and number assumptions typical for grinding, micro cutting gra...

Two different greases formulated using MoS2 and a combination of ZDDP and functionalized PTFE (F-PTFE) were examined under spectrum loading conditions where loads, frequency, and duration of the steps were treated as variables. Combination of ZDDP and F-PTFE were synergistic resulting in a significant reduction in the wear and friction under spectrum loading condition. Decreasing the time step ...

The aim of the article is an improvement abrasion resistance materials road pavements and giving practical recommendations during pavement designing to construction organizations. Prall Test method was used identify factors influencing wear asphalt concrete. Studied mixtures are typical for highway in Russian Federation Republic Tatarstan. influence such as type mix, size aggregate, binder qual...
