The atmospheric corrosion rate of materials changes based on different environmental conditions including time to be exposed to wet condition, relative humidity, surrounding temperature, and impurity of the air. The adhesive bond is relatively weak in conventional surface coating process which may lead the separation of these coatings and reduction of effective coating lifecycle. Some conventio...

The inhibiting effect of drugs towards the corrosion of different metals and alloys has been reviewed in this paper. Results of Weight loss method, Potentiodynamic polarization and Electrochemical impedance spectroscopy were investigated. Kinetic and thermodynamic parameters provide valuable information about the mechanism of corrosion inhibition. Different classes of drugs, having hetero-atoms...

The modes of erosion-corrosion are diverse and may vary from being "erosiondominated", where erosion of metal is the dominant process, to "corrosion-dominated", where erosion of oxide scale is the dominant process. The intermediate situation in which erosion of transient oxide is the predominant process is termed "erosion-corrosion-dominated" and describes the regime in which continual formatio...

This paper covers one of the building blocks required to complete a mechanistic CO2 / H2S corrosion model: electrochemistry of carbon steel CO2 corrosion in the presence of traces of H2S (3-250 ppm in the gas phase). Electrochemical impedance spectroscopy and linear polarisation resistance were used to investigate the mechanism of CO2/H2S corrosion in a glass cell at room temperature, at atmosp...

There is increasing global awareness of adverse reactions to metal debris and elevated serum metal ion concentrations following the use of second generation metal-on-metal total hip arthroplasties. The high incidence of these complications can be largely attributed to corrosion at the head-neck interface. Severe corrosion of the taper is identified most commonly in association with larger diame...

The atmospheric corrosion of Mg and MgAl alloys was investigated. Corrosion tests were performed in the laboratory under controlled environment. CP Mg, AM50 and AZ91 samples were exposed at 95% RH and 22°C in the presence and in the absence of 400 ppm CO2 for 24 h to 672 h. The passive film was characterized by means of XPS, FTIR, AES and XRD. The film consisted of MgO/Mg(OH)2 with carbonate on...

7 Corrosion of reinforcing steel in concrete can alter the interface between the steel and concrete and 8 thus affects the bond mechanism. This subsequently influences the behaviour of reinforced 9 concrete structures in terms of their safety and serviceability. The present paper attempts to 10 develop a numerical method that can simulate the behaviour of reinforced concrete walls subjected 11 ...
