This study was devoted to verifying the effect of using three different coating materials on draft requirement chisel plow shares. Four types shares with same geometric dimensions (70 mm width, 0.26 rad as lift angle and 45° for cutting angel) were used.  One share kept without its standard iron a control, other coated copper, aluminum stainless steel. Experiments conducted an open air soilbin ...

in this study, the removal of as (v) from water resources by using aluminum-coated pumice as a new adsorbent was assessed. the features of the adsorbent coating layer were observed by x-ray diffraction (xrd) and scanning electron microscopy (sem).the effects of various parameters such as adsorbent doses, ph, contact time, arsenate initial concentration and interfering ions in arsenic adsorpt...

In the Lost Foam Casting process, melting point temperature of metal, as well as volume and rate of the foam degradation have significant effect on the mold filling pattern. Therefore, gas generation capacity and gas gap length are two important parameters for modeling of mold filling time of the lost foam casting processes. In this paper, the gas gap length at the liquidfoam interface for a lo...

Epoxy powder coatings containing zinc aluminum phosphate (ZAP) and zinc phosphate (ZP), which are the 2nd and 1st generation of phosphate-based pigments respectively, were applied to the surface of mild steel sheets. The anticorrosive performances of the coated samples were studied using electrochemical impedance spectroscopy (EIS). Cathodic disbonding resistance and the adhesion performance of...

Light to wear: Aluminum coated fibrous materials with excellent electrical conductivity and mechanical endurance are fabricated at room temperature by a chemical solution process. The resulting aluminum-coated conductive papers and threads can be used in electric circuits for flexible and wearable electronics.

The aim of the current study was an in vivo evaluation of the bacterial adhesion on TiN coated orthodontic stainless steel wires in 20 patients (age15-25) undergoing fi xed orthodontic treatment who have the indication for placement of 0.019 ×0.0 25 inch Stainless steel arch wires in both jaws. TiN coatings were formed on orthodontic stainless steel wires by physical vapor deposition (PVD), The...

High energetic aluminum nanoparticles are mainly used as additive in solid rocket propellants. However, fabrication of these aluminized energetic materials is associated with decreasing the burning rate of propellants due to problems such as oxidation and agglomeration of nanoparticles. In this study, to improve combustion performance of aluminum nanoparticles, coating by metallic Ni shell...
