THE EVALUATION METHODS OF SURFACE LAYER ENERGY CONDITIONS
Journal Title: Tribologia - Year 2009, Vol 228, Issue 6
Abstract
The issue of the evaluation of surface layer energy conditions was presented in this article. A large majority of presented methods do not find application in modern tribology but mechanisms of their activity predispose them in such utilisation. The classification of these methods was accomplished in three groups: evaluation of energy accumulated on the surface, evaluation of energy accumulated in the surface layer, and intermediate evaluation. Among methods, three proposals are presenyed: method of free surface energy determination, a method makes of use the Pinkiewicz apparatus, and a method of Auger electron spectroscopy. Results of research on the evaluation of energy conditions of surface layer after cold working was submitted for these methods.<br/><br/>

POWŁOKI O ZŁOŻONEJ ARCHITEKTURZE DO ZASTOSOWAŃ BIOMEDYCZNYCH
W pracy analizowano wpływ złożonej architektury powłok Cr/CrN+a-C:H na ich właściwości mechaniczne i tribologiczne. Porównywano je z powłokami pojedynczymi CrN i wielowarstwowymi Cr/CrN, które wytwarzano techniką magnetr...
ASSESSMENT OF LUBRICITY OF MIXTURES OF FATTY ACID METHYL ESTERS DERIVED FROM VEGETABLE OILS IN FUEL OIL
The results presented are a part of the research program aimed at the optimisation of diesel fuel containing fatty acid methyl esters (FAME) derived from vegetable oils. The esters could be applied as an ecological fuel...
CHARAKTERYSTYKA TRIBOLOGICZNA WYBRANYCH PAR MATERIAŁÓW ODDZIAŁUJĄCYCH W POWIETRZU I W PRÓŻNI
Zbadano charakterystyki tribologiczne ślizgowego węzła tarcia typu kula–tarcza pracującego w powietrzu oraz próżni w warunkach tarcia technicznie suchego. Elementami testowymi były tarcze wykonane ze stali 100Cr6 bez pow...
THE STABILISATION OF THE FRICTION COEFFICIENT IN A MODEL SLIDE BEARING
The work is devoted to the cooperation of two systems of external loads: a mechanical with friction and electrochemical. The research was conducted in a model tribological system, which consisted of a rotating ring with...
THE INFLUENCE OF ENERGY CONDITIONS OF SURFACE LAYER ON THE WETTABILITY OF STEEL BY ACTIVE AND INACTIVE LUBRICATING MEDIUMS
The influence of energy conditions of steel 15 surface layer on its wettability by surface active and non-active lubricating mediums was presented in this article. Energy conditions were estimated on the basis of the ana...
