The paper presents a comparative analysis between the shear stability tests results and four ball tests results for some industrial oils. This correlation is used for establishing the way how the mechanical solicitations ...

The paper presents a method to establish a link between the shear stability index and service behaviour of motor oils. A standardized method for shearing stability establishing is combined with appropriated curve fitting ...

This paper aims to review the knowledge on materials and tribology of the ultra high molecular weight polyethylene (UHMWPE) composites. The various mechanisms proposed for the wear behaviour of UHMWPE are closely associated ...

This paper presents three test methods for conformity assessment of technical fluids, all included in international, European and Romanian standards and their relevance for work security and health.

The aim of this paper is to describe a method of coating with ceramic molecular layer, in order to obtain a MWCNTs (multiwall carbon nanotubes) functionalized surface, chemical bond energy increase and physico-chemical ...
