In this study, different disc brakes and friction materials are evaluated with respect to particle emission output characteristic features derived. The measurements take place on an inertia dynamometer using a constant volume sampling system. Brake wear factors of concepts in sizes determined compared, grey cast iron disc, tungsten carbide-coated carbon ceramic disc. were tested over section (t...

Corrosive-erosive effect on AISI D3 steel, 304 stainless steel and CrN/AlN coating in aqueous NaCl slurries was studied. CrN/AlN multilayer films with a thickness of 3 m and bilayer period of = 60 nm (50 bilayers) were obtained by using the physical vapor deposition (PVD) technique (magnetron sputtering). The corrosion-erosion experiments were performed in a test machine in which the impingemen...

the aim of this study was to determine the feasibility of coupling an electrochemical process with a biological treatment in order to degrade phosmet, an organophosphorous pesticide. the absence of biodegradability of phosmet by pseudomonas fluorescens and activated sludge was verified in our operational conditions. so, a conventional biological treatment is not appropriate for phosmet polluted...

Polymer matrix composites used in different industrial applications due to their enhanced mechanical properties and lightweight. However, these materials are subjected to friction and wear situations in some industrial and automobile applications. Therefore, there is a need to investigate the wear properties of polymer matrix composite materials. This article emphasizes the dry abrasive wear be...

The microstructures and properties of laser remelted alloy spray coatings were studied by means of wear testing, corrosion testing, microhardness testing, scanning electron microscopy, electron probe microanalysis and transmission electron microscopy. The results show that the wear and corrosion resistance of laser remelted alloy spray coatings is remarkably increased by the addition of CeO . T...

Laboratory wear testing of ultra high molecular weight polyethylene from 12 Charnley acetabular cups, removed after periods of up to 17.5 years showed that the large patient-to-patient variations in clinical penetration rate cannot be explained by batch-to-batch variation in the wear resistance of the material. Nor was there any evidence of a time-dependent degradation in wear resistance of the...

this work is aimed to evaluate the role of nanoclay in the protective performance of an eco-friendly silane sol-gel layer applied on mild steel substrate in 0.1m sodium chloride solution. at the first step, the effect of ph of the silane solution, consisting of a mixture of γ-glycidoxypropiltrimethoxysilane and methyltriethoxysilane and tetraethoxysilane, on the coating performance was evaluate...

The wear properties of biomaterials have been demonstrated to have a high importance within orthopedic bearing surfaces. This study performed a comparison of the wear between the two main grades of Ultra High Molecular Weight Polyethylene types GUR 1020 and GUR 1050 articulating against Cobalt Chromium. Such a high capacity wear comparison has not been reported elsewhere in the scientific liter...
