Purpose This paper aims to investigate the wear behaviour of different materials for cylinder liners and piston rings in a linear reciprocating tribometer with special focus on liner boundary lubrication regime. Design/methodology/approach Conventional nitrided steel, as well diamond-like carbon chromium nitride-coated rings, were tested against cast iron, AlSi Fe-coated liners. The experiments carried out samples produced from original engine parts have surface topography available....
By studying metal growth on Pt(111), we determine the reasons for high island densities observed in pulsed laser deposition (PLD) compared to conventional thermal deposition. For homoepitaxy by PLD with moderate energies ($\ensuremath{\lesssim}100\text{ }\text{ }\mathrm{eV}$) of deposited ions, are caused instantaneous flux arriving particles. Additional nuclei formed at ion ($\ensuremath{\gtrsim}200\text{ adatoms created impinging ions. heteroepitaxy, density is also increased intermixing...
To describe and predict wear in a tribosystem, theoretical formulas empirical models exist.Most of the existing formulations have short range validity can only be applied for specific contact situation.In this paper, aim is to investigate technical application tribocontact an internal combustion engine.In particular, between piston skirt cylinder liner experimentally simulated using linear reciprocating tribometer original engine parts, under closeto-reality loading conditions.The...
New engine strategies, such as frequent start-stop operation and increasingly severe loading conditions due to efforts optimize performance efficiency, lengthen the time bearings spend in mixed or even boundary lubrication regimes. To investigate how regime affects bearing bush wear, a series of tests were performed at distinct positions on Stribeck curve, representing, closely possible, boundary, hydrodynamic Both friction wear measured throughout test, while evolution surface roughness was...
