2. Investigation of Physicochemical Characteristics of Heavy, Medium and Blend Crude Petroleum on Corrosion Resistance of AISI 1020 Carbon Steel
This work investigates the influence of the physicochemical characteristics of heavy (17.5 °API), medium (28.3 °API) and blend (50% heavy + 50% medium) crude petroleum on corrosion of AISI 1020 carbon steel at 25.0 ± 1.0°C. The corrosion resistance of steel was analyzed by electrochemical impedance spectroscopy, potentiodynamic polarization, and scanning

3. Characterization of Different Surface Layers Produced by Solid Boron-Nitro-Carburizing Thermochemical Treatment on AISI 1020
The aim of this study is to obtain and characterize surface layers on low carbon steel with the pack boron-nitro-carburizing process. Different mixtures of commercial powders (Turbonit® and Ekabor®) were used to investigate the case properties, microstructure and phases formation on AISI 1020 steel. A series of experiments were conducted in solid medium wi

4. EXTRATO DE HIBISCO-COLIBRI COMO INIBIDOR VERDE DE CORROSÃO DO AÇO-CARBONO EM ÁCIDO SULFÚRICO
For this work, a hydroalcoholic extract was prepared from the aerial parts of the Malvaviscus arboreus (Malvaceae) species, popularly known as hibisco-colibri in Brazil; and then, investigated by infrared and NMR spectroscopy. A class of special metabolites containing a porphyrin skeleton and pyrrole units was determined by typical absorption spectra, mainly

5. Glycerol Effect on the Corrosion Resistance and Electrodeposition Conditions in a Zinc Electroplating Process
Zinc electrodeposition is an economical process of Zn coating compared to conventional galvanic process. The galvanizing process is used in various industrial sectors to protect ferrous alloys during the corrosion process. In buildings, the galvanizing process is widely used to coat mortar protective screens. The electrodeposition of zinc has a relatively lo

6. Microbiologically-Influenced Corrosion of 1020 Carbon Steel in Artificial Seawater Using Garlic Oil as Natural Biocide
This work aims evaluate the use of biocides in the microbiologically-influenced corrosion (MIC) of AISI 1020 carbon steel by sulfate-reducing bacteria (SRB) in artificial seawater. A natural biocide (garlic oil) and a commercial biocide (glutaraldehyde) were used to control the corrosion caused by these bacteria in artificial seawater. Microbial growth on th

7. Mejora de la resistencia al desgaste abrasivo de un revestimiento Fe-Cr-Mn-C mediante la adición de V
ABSTRACT The aim of this work is to increase the abrasive wear resistance of a coating, applied on plates of AISI 1020 carbon steel, using tubular coated electrodes with the Fe-Cr-Mn-C alloy system. In order to achieve this increase, V was added to the alloy system. The resulting coating were studied using optical microscopy (MO), X-ray diffraction and micro

8. Investigation of Austenitic Stainless Steel Coatings on Mild Steel Produced by Friction Surfacing Using a Conventional CNC Machining Center
The friction surfacing process allows deposition of similar and dissimilar coatings in the solid state, avoiding some of the problems associated with conventional coating methods in which fusion is involved. In the present work, a viability assessment of producing AISI 304 austenitic stainless steel coatings on AISI 1020 low-carbon steel substrates using a m

9. Anticorrosive Effect of PVP 40000 Against AISI 1020 Carbon Steel in HCl
Polymers have received considerable attention for replacing synthetic inorganic and organic anti-corrosion inhibitors since they are not as toxic for the environment, besides being cheaper. Polyvinylpyrrolidone (PVP) has been studied due to its applicability, solubility, very low toxicity, cost and efficiency in corrosion inhibition against metals, such as z

10. Characterization of Niobia-alumina Deposited by the Sol-gel Process on Carbon Steel
The precursor sols of Al2O3 and mixed NbxOy/Al2O3 oxides were synthesized by the sol-gel process using acetylacetone to control the reaction kinetics of the organometallic oxides in the mixture. The layers of the precursor sols of Al2O3 and NbxOy/Al2O3 were deposited on AISI steel 1020 by manual immersion (dip coating). The lyophilized sols were characterize

11. Cu-Sn Coatings Produced Using Environmentally Non-Aggressive Electrolyte Containing Sodium Tartrate
This work proposes the production of Cu-Sn alloy coatings with anticorrosive properties, using an environmentally non-aggressive bath. The coatings were electrodeposited on carbon steel substrate AISI 1020 using an electrolyte containing CuCl2 and SnCl2, and sodium tartrate as the complexant agent. The produced coatings were characterized by scanning electro
