STUDY OF POLYPYRROLE FILMS MODIFIED WITH COPPER AND SILVER MICROPARTICLES BY ELECTROCHEMICAL CEMENTATION PROCESS
(Sociedad Chilena de Química, 2006)
Cyclic contact fatigue of cemented carbides under dry and wet conditions: Correlation between microstructure, damage and electrochemical behavior
(Elsevier, 2020-11)
The correlation between the damage induced under cyclic contact fatigue and their electrochemical behavior (anodic polarization curves) for different WC-Co-based cemented carbides grades was investigated at the macrometric ...
Industrial Byproduct-Based Concrete Subjected to Carbonation. Electrochemical Behavior of Steel Reinforcement
(ESG, 2012)
Samples of ASTM A-706 structural steel embedded in different concretes obtained from mixtures of alkali-activated steel slag and fly ash were exposed to accelerated carbonation under controlled conditions (4% CO2, 65% RH ...
Electrochemical behaviour of steel in mortar and in simulated pore solutions: Analogies and differences
(Pergamon-Elsevier Science Ltd, 2016-10)
On evaluating the corrosion resistance of concrete, it is frequent to performelectrochemical tests in the so called simulated pore solutions (SPS) to replace tests performed in concrete specimens. Besides, to study the ...
Synthesis of a hole-containing polypyrrole film modified by copper cementation
(John Wiley & Sons Inc, 2016-07)
A simple procedure enables to obtain a hole-containing PPy film on SAE 4140 steel in sodium bis(2-ethylhexyl) sulfosuccinate (AOT) solutions. The film characterization was made by electrochemical and morphological studies. ...
A migrating corrosion inhibitor evaluated in concrete containing various contents of admixed chlorides
(Pergamon-Elsevier Science Ltd, 2002-02)
The performance of a surface-applied migrating corrosion inhibitor (MCI) based on an alkylaminoalcohol was evaluated on concrete specimens containing reinforcing steel bar (rebar) segments. Two water/cement ratios (w/c's), ...
Estudos de Durabilidade Frente ao Ataque Ácido de Compósitos Portland-Polímero para Cimentação de Poços de Petróleo
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Ciência e Engenharia de MateriaisProcessamento de Materiais a partir do Pó; Polímeros e Compósitos; Processamento de Materiais a part, 2008-04-25)
Portland-polymers composites are promising candidates to be used as cementing material in Northeastern oil wells of Brazil containing heavy oils submitted to steam injection. In this
way, it is necessary to evaluate its ...
Avaliação de cloretos pelo método de aspersão de solução de nitrato de prata
(Universidade Católica de Pernambuco, 2011-06-13)
The corrosion by chlorides is considered by a number of researchers the most dangerous pathological manifestation attacking concrete reinforcements. The assessment of the attacks to the structure by sodium chloride is ...

Influence of the microstructure on corrosion induced damage of WC-Co cemented carbides
(Maney Publishing, 2020-05)
The main goal of the present work is to study the influence of the microstructure on the corrosion behavior of cemented carbides WC-Co in two corrosive media. Corrosion kinetics were determined by immersion tests while the ...
