The aim of this study was to deyelop a noyel hydroxyapatite (HA) coating method on zirconia using glass coating technique. A borosi)icate glass, the mixture of the glass ttnd HA (3e, 50, 70, and 90 mass%), and the 100% HA were coated on two kinds of zirconia discs and fired at 900-950'C. After the final coating, the surface of the sample was etched for 3 min in an acid-mixture of 3% HF and 5%HN...

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...

There are many ways to coat tablets. Coatings are a very important part in the formulation of pharmaceutical dosage form to achieve excellent formulation quality (e.g., color, texture, mouth feel, and taste masking), physical and chemical protection for the drugs in the dosage forms, and modification of drug release characteristics. Most film coatings are applied as aqueous or organic-based pol...

the corrosion protection of mild steel by a newly developed epoxy-based coating system containing inherently conducting nanopolyaniline-clay as a nanoadditive has been studied. polyaniline-clay anticorrosion nanoadditive (pcna) was obtained by the direct mixing method of nanopolyaniline (0.03 wt.%) and organo-modified clay (3 wt.%) at atmospheric pressure, and xrd technique was used to study d-...

A novel in-line technique utilising pulsed terahertz radiation for direct measurement of the film coating thickness of individual tablets during the coating process was previously developed and demonstrated on a production-scale coater. Here, we use this technique to monitor the evolution of tablet film coating thickness and its inter-tablet variability during the coating process under a number...

Abstract 316L stainless steel is one of the metal biomaterials used in implant applications because it has excellent mechanical strength. To improve biocompatibility and activity metals, a coating on surfaces required. coated with hydroxyapatite using dip technique. Firstly, suspension was prepared by mixing 10 grams hydroxyapatite, 1 gram sago starch, distilled water certain weight which then ...

The target was to study and develop industrially suitable methods to apply thermoplastic coatings on plywood. Typically, wear and climatic resistance for wooden sheets, such as chip board and plywood, is achieved by thermosetting resin coating (e.g. phenolformaldehyde). However, economical and environmental issues are driving towards thermoplastic coatings (e.g. polyethylene) in such products. ...
