Plasma electrolytic oxidation (PEO) was performed on a 1010 Aluminum alloy. To achieve thenanocomposite structure, Si3N4 nanoparticles were added into the electrolyte. In an alkaline aqueoussuspension (silicate-based), the effect of adding NiSO4 on the applied voltage, microstructure,composition, wear, and corrosion resistance of PEO coatings was investigated using ScanningElectron Microscopy (...

Babbitt is a white silvery alloy that composed of Tin, Lead, Copper and Antimony. This alloy is the most current bearing alloy in industrial applications. The characteristics of this alloy, such as high wearing resistance and low coefficient of friction, have converted it into a bearing cover. The target of this study is investigation on the effects of alloy elements on wearing and micro-struct...

Computer algorithms are proposed for the estimation of wear appearing in artificial hip joints using finite element analysis based on the modified Archard's wear law, contact features and an analogue wear process. A pin-on-disk plate experiment is reconstructed to assess the efficiency and validity of the algorithms proposed here. Through the successful verification of wear depth and volume los...

Ti-6Al-4V titanium alloy has great application in medicine and military industries due to its capabilities, namely high strength to weight ratio and corrosion resistance. In the current research, the effect of aging treatment on microstructure and wear behavior of Ti-6Al-4V titanium alloy was investigated. Pin on disk wear test was applied to assess the wear behavior. Specimens were first solut...

Ni-W coatings, compared to pure nanocrystalline Ni, exhibit higher hardness and wear resistance. In some cases, these coatings are considered as environmental friendly alternatives for hard chromium coating. Till now, most of Ni-W coatings have been produced by direct current electrodeposition from alkaline baths. In this study square pulse current was used for deposition of Ni-W precipitates f...

The introduction of biodiesel to commercial diesel is being increased every year. need check this addition the engine and lubricant important for automakers internal combustion manufacturers. oil analysis technique a type predictive maintenance, done by collecting from equipment analyzing it later in laboratory, or directly continuously on-line systems. In engines, all parts have pre-establishe...

Since the 80’s, industrial core calculations employ two-step scheme based on prior cross sections preparation with few energy groups and in homogenized reference geometries. Spatial homogenization fuel assembly quarters is most frequent calculation option nowadays, relying efficient nodal solvers using a coarse mesh. Pin-wise reaction rates are then reconstructed by dehomogenization techniques....
