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...

in this study, physical vapor deposition (pvd) ti-cr-n coatings were deposited at two different temperatures100 and 400ºc on hardened and tempered tool steel substrates. the influence of the applied deposition temperature on the physical and mechanical properties of coatings such as roughness, thickness, phase composition, hardness and young’s modulus were evaluated. phase compositions were stu...

Hot-melt coatings (HMC) are widely used to provide drug protection, to increase aesthetic value of products, to reduce acidity if vitamins, to provide lubrication and modified drug release. In hot-melt coating the substrates are coated with molten form of coating materials. Substrates used for coating are beads, capsules, granules, pellets, pills, spherules and tablets. Hot-melt coating devoid ...

A microlens array (MLA) based see-through, front projection screen, which can be used in direct projection head-up displays (HUD), color teleprompters and bidirectional interactive smart windows, is evaluated for various performance metrics in transmission mode. The screen structure consists of a partially reflective coated MLA buried between refractive-index-matched layers of epoxy as reported...

in the present study, ni-p-cnt composite coating was successfully fabricated via electroless plating. scanning electron microscopy (sem) was used to characterize the coatings. the effect of cnts concentration in the bath on its content in the composite coatings was studied. furthermore, the corrosion behaviour of the coatings with different contents of cnts was evaluated using tafel polarizatio...

The idea of smart inhibitors is based on the principle that an inhibitor is used where needed. This will reduce the use of inhibitors and protect materials in hostile environments. On the other hand, direct addition of the inhibitor within the coating can be harmful, resulting in the loss of inhibitors ability, deterioration in the coating or both of them. An appropriate method for solving thes...

Functional conducting polymeric composites with micro and nano structures have received great attention due to technological applications in electrical, optical, magnetic materials devices. Electrically conductive textile surfaces are used for smart/functional such as electromagnetic shielding, anti static coatings, wearable electronic sensors, heat generating textiles etc. In this study, micro...

in this study, the potential use of nano-coatings for food packaging industry has been investigated. therefore, this study has been presented in three sections: the application of nanocoatings in the food industry, natural, edible and biodegradable nano coatings. the use of nanoscale or multiatomic coatings have presented specific features in the packing industry. coatings which have shown thei...
