Abstract The lubricity of coatings made from different types carbon nanoparticles such as onions, nanohorns and nanotubes is investigated on line-patterned AISI 304 stainless-steel substrates using ball-on-disc tribometry over 200,000 sliding cycles. Picosecond direct laser interference patterning used to create line-patterns the substrate surfaces which are subsequently coated by electrophoret...

This paper deals with the preparation and characterization of Nickel-coated Alumina ceramic particles by Electroless Plating Technique. Nanosized α-Al2O3 powders of about 50nm in diameter are used for plating. The bath for Electroless Nickel Plating is prepared with NiCl2.6H2O, C6H5NaO7.H2O, NH4Cl and NaH2PO2.H2O. A bath temperature of 85°C, pH value of 8 and stirring time of 20 min is consider...

It has been known that a high-emissivity furnace provides an energy-efficient alternative to a conventional furnace [1,2]. To improve the efficiency of a furnace, ceramic coatings with high emissivity are often applied to the interior of the furnace. The purpose of this paper is to show the amount of electrical energy-saving achieved by emissive carbon coating for a tubular vacuum-furnace. Alum...

Sealing treatment is a post-surface of the plasma spray coating process to improve corrosion resistance material. In this study, effect sealing on and adhesive strength spray-coated alumina coatings was analyzed. For sealing, an epoxy resin applied surface coated specimen using brush. The subjected salt test for up 48 hours microstructural analysis revealed that in layer/base material interface...

In this study, multi wall carbon nanotubes (MWCNTs) were synthesized by Chemical vapor deposition (CVD) method using two different catalysts (Fe nanoparticles) and (Ni nanoparticles) with  two different substrates: Quartz and Alumina. Acetylene gas was used as a carbon source and Argon as a carrier gas at different temperatures and different times to study the effects of these parameters on CNT...

Cysteic acid functionalized mineral oxide nanoparticles can be used to impart superhydrophilic performance on a range of woven and non-woven fabrics. Woven fabrics spray dip coated alumina iron based cysteic nanoparticles, were characterized by SEM, EDX the change in water contact angle was measured or where increased hydrophilicity sufficiently great that time for adsorption droplet measured. ...
