in the present study, the effects of growth defects and chromium content loss on the degradation of corrosion andpassivation of cathodic arc evaporation (cae-pvd) of stainless steel coating were investigated in 2 m sulphuricacid solution. eds analysis indicated that the micro-particles were obtained during the coating growth. in addition,it was detected that the growth defects had poor adhesion...

One of the common methods used in pharmaceutical industry to coat tablets is add a thin polymer-based coating tablet or granule that contains medicament. Solid dosage forms, such as capsule pill, are frequently used. Controlled release one primary causes. The amount on surface has significant impact how effective oral form is.
 Tablets typically coated by spraying specialised solutions ove...

Crack-free Cu alloy coating has been fabricated on Al substrate with the existence of a Ag buffer layer. The had 12 at.% and 45 Ag, which contributed to formation solid solution eutectic phase (transformation temperature 780 °C). was characterized as finer solution. layer main contents Ag2Al solution, it not only hindered brittle intermetallic compounds (IMCs)but also reduced thermal stress its...

The addition of Cr nanoparticles to a plasma electrolytic oxidation (PEO) electrolyte offers the possibility producing layers with broader range coating compositions and improved properties. In this study, effects various voltages on formation, microscopic morphology, phase composition were investigated in situ incorporation into PEO-coated Mg alloy. results show that corrosion performance was ...

objective: a clinical challenge of using zirconia frameworks is to achieve adequate bond with different substrates. this study aimed to evaluate the effect of bioglass and silica coating of zirconia substrates on microshear bond strength of resin cement to tetragonal zirconia. methods: this laboratory experimental study was conducted on zirconia discs. a total of 120 ytzp zirconia (zirkonzahn) ...

The aim of the present research is to convert bioinert surface of NiTi to bioactive and biocompatible surface. In order to develop a bioactive and corrosion resistant film on NiTi, electrophoretic deposition process was done and TiO2 particles were deposited on the NiTi surface. Suspensions including TiO2 particles were prepared using a mixture of acetone and n-butanol (0%, 30%, 60%, 80% and 10...

Significant efforts have been devoted to synthesis and characterization of engineered silicon nanostructures able to withstand the large stresses and strains produced by lithium alloying/dealloying reactions during electrochemical cycling. Less attention has been given to ensuring robust connection between silicon and its host structure in the anode. The current work develops a new methodology ...
