1. Effect of the Incorporation of Micro and Nanocellulose Particles on the Anticorrosive Properties of Epoxy Coatings Applied on Carbon Steel
Polymeric coatings may act as a physical barrier between the aggressive ions and the metal substrate. However, prolonged exposure may cause damage to the polymer coating, leading to a continuous reduction of the barrier effect and consequently loss of the corrosion protection. The objective of this study is to determine the effect of aminopropyltriethoxysila

2. Obtención y caracterización de recubrimientos de biovidrio sobre la aleación de Mg AZ31
ABSTRACT The ideal material for a metal bone prosthesis must undergo a gradual corrosion in vivo, without releasing toxic components, while acting as a support and facilitating the growth of bone tissue, until a replacement is completed by the regenerated bone. . Biodegradable magnesium alloys have been studied because of their excellent mechanical propertie

3. Síntesis y caracterización de “tanatos” de lantano como inhibidores de la corrosión
ABSTRACT Tannins are polyphenols synthesized by plants. They are found in Quebracho (Schinopsis Balansae) wood, Tara (Caesalpinia spinosa) fruits, etc. They have been incorporated in the coating industry as "antifouling" agents and as corrosion inhibitors in acidic solutions. Moreover, lanthanum solutions have a great inhibitory effect over SAE 1010 steel co

4. Influence of the Addition of Montmorillonite in an Epoxy Powder Coating Applied on Carbon Steel
AbstractPolymer coatings have been used for the corrosion protection of metal surfaces acting as a physical barrier against several corroding media. In spite of the good efficiency of these coatings their resistance is limited due to the presence of localized defects which give place to localized corrosion. Aiming to improve the barrier properties of these c

5. Preparation of PMMA/hBN composite coatings for metal surface protection
Polyacrylics have been widely used in coatings. However, their application is limited by low corrosion resistance. One way to enhance their properties is the addition of fillers with adequate properties. In this study, composite materials of PMMA and hBN were developed and deposited on steel by dip-coating. The influence of the amount of hBN in the PMMA coat

6. Análise de simulantes para produtos ácidos acondicionados em embalagens metálicas / Analysis of simulants to acidic products conditioned in meal package
Tin-plate cans represent most of the cans for canned food. Since they are not inert, during the storage period, interaction occurs with the product and metal dissolution can occur, especially when it is acid food. To minimize this interaction it is used organic coatings, and epoxy-phenolic resin is the the most used. As the foods are complex biochemical syst

7. Avaliação técnica e microestrutural entre tijolos dolomíticos de alto desempenho para a indústria siderúrgica
The refractory dolomite is widely used as coating for ladles work in steelmaking process for its excellent refractoriness in terms of service. The use of this refractory is due to a natural formation of a protective layer, which enhances the life of the refractory, resulting in increased equipment life. This work is based on a comparative study between two b

8. âRevestimento por soldagem MIG/MAG empregando ligas de nÃquel para apliacaÃÃes em componentes do setor de petrÃleo e gÃs naturalâ / Gmaw Welding Overlay Of Nickel-Based Alloys For Applications In Oil And Natural Gas Components
The weld overlay of nickel-based alloys is an alternative often used in oil and gas industry to prevent corrosion in pipes and equipments operating under severe conditions. In many situations the requirements of weld overlays are based in a maximum of 5% iron content in the weld metal to ensure corrosion resistance. The aim of this study was to determine the

10. Influence of high frequency and moderate energy pulses on DLC deposition onto metallic substrates by magnetron sputtering technique
The deposition of Diamond-like carbon (DLC) films brings excellent mechanical, chemical, optical and electronic properties to a large range of materials. However, a problem to be overcome is its poor adhesion on metallic substrates. Usually, a silicon layer must be deposited on the surface of metals previous to DLC film deposition. In fact, in our experiment
