Study of the main variability aspects of surface texture of steel in face milling
Petropoulos, G.; Pandazaras, C.; Stamos, I. (2003)The investigation of basic variability aspects in face-milled surfaces regarding roughness and waviness (surface texture) for various cutting conditions is attempted in this note. The inhomogeneity of the machined steel ... -
Surface anisotropy for monitoring the wear of IC engine cylinders
Pandazaras, C.; Petropoulos, G. (2004)The present work proposes a methodology for monitoring the wear of internal combustion engine cylinders. This could be useful in calculating the time at which maintenance should be done on such a tribosystem or in determining ... -
A surface roughness analysis in turning of polyamide PA-6 using statistical techniques
Mata, F.; Petropoulos, G.; Ntziantzias, I.; Davim, J. P. (2010)This work is aimed at studying the impact of cutting conditions (cutting speed and feed) on surface roughness in turning of Polyamide PA-6, using two different cutting tool materials namely, Polycrystalline Diamond (PCD) ... -
Tribological coatings for aerospace applications and the case of WC-Co plasma spray coatings
Koutsomichalis, A.; Vaxevanidis, N.; Petropoulos, G.; Xatzaki, E.; Mourlas, A.; Antoniou, S. (2009)Friction and wear requirements in aerospace systems are dictated by life limiting problems. One challenge is the broad range of contact stresses and sliding speeds for various movable devices. Another challenge is the ... -
Tribological design of hydrodynamic sliding journal bearings - formulating new functional charts
Pandazaras, C.; Petropoulos, G. (2005)Purpose - This paper aims to introduce an innovative methodology for the determination of operational characteristics of journal bearings (j-bs) through using new type charts based upon a numerical solution of the Reynolds ... -
WEAR, CORROSION AND MECHANICAL BEHAVIOUR OF PLASMA-SPRAYED CR2O3 COATINGS ON MILD STEEL
Koutsomichalis, A.; Vaxevanidis, N.; Petropoulos, G.; Mourlas, A.; Antoniou, S. (2010)In the present paper we report on the surface microstructure, tensile behaviour and the tribological behaviour of plasma-sprayed chromium oxide (Cr2O3) coatings on steel substrates. Plasma-sprayed chromium oxide coatings, ...
