Uniform nanostructure coating of TiO2 was prepared on 316L stainless steel by sol-gel method using Tetra-n-Butyle Titanat (TBT) as alkoxide material. 316L specimens were coated with the mentioned sol by dip coating method. The influences of preparation condition, pH of sol on TiO2 nanostructure coating were investigated. Their structural properties were examined at var...

Abstract A novel hybrid sol–gel coating has recently been introduced as an alternative to high toxic chromate-based corrosion protection systems. In this paper, we propose a multiscale computational model to estimate the amount and time scale of inhibitor release of the active corrosion protection coating. Moreover, we study the release rate under the influence of parameters such as porosity an...

Lead Zirconate Titanate oxide (PZT) thick films with thicknesses of up to 10 μm were developed using a modified sol-gel technique. Usually, the film thickness is less than 1 μm by conventional sol-gel processing, while the electrical charge accumulation which reveals the direct effect of piezoelectricity is proportional to the film thickness and therefore restricted. Two approaches were adopted...

Abstract This paper aims to fabricate new superhydrophobic nanocomposite coating materials protect the inner surfaces of petroleum pipelines from corrosion. The batch emulsification polymerization technique (BEM) was used as a facial eco-friendly prepare three hydrophobic (styrene/vinyl acetate) copolymers. sol–gel method SiO 2 nanoparticles (SiO -NPs) with average size ranging 90 101 nm. funct...

Sol-gel coatings provide environmentally friendly surface protection for metals and can replace toxic pre-treatments such as those based on hexavalent chromium metal alloys. This project ultimately aims to develop silica-based organic–inorganic sol-gel derived thin film possessing anti-corrosion anti-fouling properties aluminium alloy substrates. As with any coating, sample preparation plays a ...

When producing implant materials, achievement of optimal bioactivity and biocompatibility are essential. Nanocoatings can provide an efficient cost effective way to alter the interactions of the implant material with its destined "host" environment. Nanocoatings of sol-gel derived carbonated hydroxyapatite (HAp) and zirconia were produced in this study. The surfaces were characterised by Fourie...

Terbium doped Y2O3 planar waveguides were fabricated by sol–gel process and dip-coating using yttrium acetate as precursor. Two different doping modes were compared, i.e. introduction in the sol of dispersed Tb3+ions from dissolved Tb(NO3)3, or of nanoparticles of Tb2O3 or [Y2O3:50% Tb] from an alcoholic suspension. The chemical and nanostructural properties were analyzed by infrared spectrosco...

This study presents the development of a method for washcoating Ni/boehmite gels, prepared by sol–gel process, onto surface commercial ceramic monolith. Indeed, cordierite monolith in honeycomb shape was used as substrate Ni/Al2O3 deposition. An experimental assembly made order to apply coating on surface. Different suspensions were with various viscosities, and multiple parameters tested withd...
