Silver-PTFE metal matrix composite coatings were deposited onto ANSI 304 stainless steel to assess the potential of using a novel non-cyanide electroplating process to produce a corrosion resistant, self-lubricating composite coating. During this study, 32 different bath parameter sets, derived from 5 variables were used to develop the non-cyanide electroplating process without the use of a sur...

nanosized tio2 particles were prepared by sol–gel method. the tio2 particles were co-deposited with chromium using electrodeposition technique. in investigating of coating surfaces by scanning electron microscope (sem), the results showed that the morphology of the coating surface was changed by adding tio2 nanoparticles to the chromium coating. the corrosion behavior of the coatings was assess...

The polysaccharide based composite biomaterial (coating) used in preserving fruits and vegetables during storage is attracting increased attention as it biodegradable material that prolongs shelf life. In the present investigation, chitosan–pullulan (50:50) edible coating was prepared with pomegranate peel extract (0.02 g/mL) an active antioxidant agent. effect of treatment enriched on life man...

Fresh-cut fruits have a shorter shelf life due to its perishable nature. Edible coating being biodegradable and environmental friendly, provides protective covering fresh-cut fruits. This review covered the effects of edible on fresh cut fruits, i.e., apple, apricot, banana, kiwi, mango, papaya, pineapple, strawberries, watermelon melon. It was observed that positively affected weight loss, tit...

The zincZeolite Socony Mobil-Five nano-particles (Zn-ZSM-5 NPs) composite was prepared and applied successfully as a new coating material to improve the corrosion resistance of steel. The corrosion type and quality of both pure zinc and our new coating material, Zn-ZSM-5 NPs, were studied using mass loss, impedance and electro-chemical polarization techniques in a sodium chloride solution. Obta...

simple and economic coating monitoring technology. The light-emitting properties of the novel coating can serve as an indicator layer, which warns when the coating has worn off, replacing or recoating is necessary [7]. When we inspect on coating with a hand-held UV-lamp, the yellowgreen light of SrAl2O4:Eu, Dy3+ will disappear. It means that the functional coating is worn out and that recoating...

Many techniques for the surface modification of titanium and its alloys have been proposed from the viewpoint of improving bioactivity. This paper contains an overview of surface treatment methods, including coating with hydroxyapatite (HAp), an osteoconductive compound. There are two types of coating methods: pyroprocessing and hydroprocessing. In this paper, hydroprocessing for coating on the...

introduction : pistachio (pistaciavera l.) is a tasty nut and a good source of nutrients. ithas a high content of numerous beneficial nutritive and bioactive compounds such as proteins, carbohydrate, moisture, vitamins, minerals, fiber and other micronutrients compounds, but the most exceptional components are the amount of fats and especially unsaturated fatty acids. therefore, this nut is hig...

Flexible, light weight and low cost electroactive coating has been fabricated by the dispersion of inorganic ferroelectric submicron particles in a polyurethane matrix. BaTiO3 particles have a mean diameter of 300 nm. The poling process and the influence of volume fraction of BaTiO3 on the piezoelectric activity of the coating have been reported. This spray coating has been realized on 1.6× 1.6...
