The development of composite materials (CM) in the systems “metal-refractory compound” is one of the up-to-date trends in design of novel materials aimed at operating under the conditions of significant loads at high temperature. To design such material, ... see more

This paper reports the comparative investigation of effect of cutting parameters i.e. cutting speed, feed and depth of cut on power consumption and too wear during turning operation of EN31. Three cooling techniques were employed during the turning operat... see more

In order to improve the tribological properties of an engine piston ring and enhance its service life, magnetron sputtering technology and low temperature ion sulphurizing treatment technology were used to prepare CrMoN/MoS2 solid lubricant coating on the... see more

Nowadays, hydropower plants are forced to have more frequent power control and the self-lubricated bearings used in the applications are one of the most critical components affected by the continuously changing operating conditions. In this study, microst... see more

Recording of Stribeck-like curves is a common way to study the effect of laser-patterned surfaces on the frictional efficiency. However, solely relying on the coefficient of friction when identifying the lubrication regime and the underlying working princ... see more

The increasing demands of environmental protection have led to solid lubricant coatings becoming more and more important. A new type of MoS2-based coating co-doped with Cu and Al prepared by magnetron sputtering, including Cu/MoS2 and Cu-Al/MoS2 coatings,... see more

The intention of this work was to evaluate the growth of Pseudomonas aeruginosa (C1 LBPVMA-UFAL) on lubricant oil and verify the production of rhamnolipid biosurfactant. Tests in solid medium containing lubricant oil supplemented with different sources of... see more

As key elements in plenty of rotating machinery, the elastohydrodynamic performance of journal bearings should be carefully checked in light of the design and operating parameters considered. This first part of the current study aims to numerically analys... see more

The presence of highly electronegative atoms in Li-ion batteries anticipates the formation of s-hole regions that may strongly affect the ionic conductivity. The s-hole consists of a region of positive electrostatic potential extending in the direction of... see more
