In this study the bioactivity of hydroxyapatite/poly(ε-caprolactone)–poly(ethylene glycol) bilayer coatings on Nitinol superelastic alloy was investigated. The surface of Nitinol alloy was activated by a thermo-chemical treatment and hydroxyapatite coating was electrodeposited on the alloy, followed by applying the polymer coating. The surface morphology of coatings was studied using FE-SEM and...

composite electrodeposition is a low-cost and low-temperature method, which is used to make metal matrix composite coatings. in this study the surfactant of anionic(sds) and cationic (ctab) is used as additive in composite coating of ni/tin. the results showed that the anionic surfactant caused more particles in the composite coatings. increasing sds concentration to the optimal value leads to ...

Powder particle coating is the most important techni It has constantly being refined and modified since last four decades. There numerous applications of coating, including drug layering, modified release coating, physical and chemical protection, aesthetic purpos identification of drugs. Various coating techniques from conventional pan coating to laser assisted solvent free techniques have bee...

to improve the corrosion protection of copper metal, 0.01m concentration of 1h-1,2,4-triazole-3-thiol (tat) was incorporated into the hybrid sol-gel monolayers containing 3-glycidoxypropyltrimethoxysilane (gptms) and tetraethoxysilane (teos). it was further subjected to hydrolysis and condensation reaction to form a sol-gel matrix. the tat-doped hybrid sol-gel coating was applied over the coppe...

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...

Slot die coating technology is a function of the coating process, auxiliary system and fundamental technique. The decision to utilize a coating technology needs to be analyzed against these functions to determine best fit. In the era of clean, thin and precise converting operations, a customized coating system is necessary to have a technical edge. Building the system from the material up to th...

Tongue inspection is a unique and important method of diagnosis in traditional Chinese medicine (TCM). It is a diagnostic approach which involves observing the changes in the tongue proper and tongue coating in order to understand the physiological functions and pathological changes of the body. However, the biological basis of TCM tongue diagnosis remains to be poorly understood and lacks syst...

A protocol is described to assess self-healing of crack damage in a polymer coating deposited on a substrate containing a microvascular network. The bio-inspired coating/substrate design delivers healing agent to cracks in the coating via a three-dimensional microvascular network embedded in the substrate. Through capillary action, monomer flows from the network channels into the crack plane wh...
