Corrosion protection of metals and alloys is a prime activity of technical, economic, environmental, and aesthetical significance. The use of inhibitors is one of the best choice of combating metals and alloys against detoriation against environmental impact. The toxicity of organic and inorganic corrosion inhibitors to the environment has provoked the search for ecofriendly corrosion inhibitor...

Corrosion is a deterioration of a metal due to reaction with environment. The use of corrosion inhibitors is one of the most effective ways of protecting metal surfaces against corrosion. Their effectiveness is related to the chemical composition, their molecular structures and affinities for adsorption on the metal surface. This review focuses on the potential of ionic liquid, polyionic liquid...

In marine environment, the physical and mechanical performances of reinforced concrete members will vary distinctly with time, which reduces the safety of the structures. The main factors influencing the durability of reinforced concrete members include the deterioration of concrete, the reduction of reinforcing bar strength, the decrease of reinforcing bar area, the weakening of the bond stren...

In this study, the synergistic effects of abrasion and corrosion on UNS S30403, S31603 and S32760 stainless steels have been investigated using micro-abrasion test rig. The stainless steel samples have been studied under both pure abrasion (PA) and abrasion–corrosion (AC) conditions imulated by using silicon carbide based slurries in either distilled water or 3.5% sodium chloride solutions. Tes...

the synthesis of polyaniline- fe2o3 nanocomposite coating on aluminum alloy 5052 (aa5052) surface has been investigated by using the galvanostatic method. the anticorrosion performance of polyaniline-fe2o3 coating was investigated in 3.5% nacl solution by the open- circuit potential (ocp), tafel polarization technique and electrochemical impedance spectroscopy (eis). the corrosion rate of polya...

This paper provides a review of the state of the art on the study of the fatigue behaviour of mechanical components coated with thin hard corrosion-resistant coatings such as the physically or chemically vapour deposited ones. Some references address the experimental characterization of the fatigue resistance of coated steel and light alloys. Some coatings have been observed to prove effective ...

Corrosion behavior of Ni20Cr coatings deposited by HVOF (high velocity oxygen-fuel) process was evaluated in ZnCl2-KCl (1 : 1 mole ratio) molten salts. Electrochemical techniques employed were potentiodynamic polarization curves, open circuit potential, and linear polarization resistance (LPR) measurements. Experimental conditions included static air and temperatures of 350, 400, and 450°C. 304...

The need for fuel efficiency and increased performance in transportation systems continually places new demands on the materials used. The design criteria which automobile and aerospace industries are primarily concerned with are density, strength, stiffness, and corrosion resistance. Low-density materials may reduce fuel costs, increase range, and allow larger payloads. High strength and stiff...

FOREWORD Salt-induced reinforcing steel corrosion in concrete bridges has undoubtedly become a considerable economic burden to many State and local transportation agencies. Since the iron in the steel has a natural tendency to revert eventually to its most stable oxide state, this problem will, unfortunately, still be with us, but to a much lesser degree due to the use of various corrosion prot...

Economic losses due to corrosion are direct, as well as, indirect and affect the economy of country. Corrosion inhibitors are one of the widely used methods to control corrosion. Particular advantage of corrosion inhibitor is that often can be implemented or changed in situation without disturbing a process. Due to toxic nature and high cost of some inhibitors currently in use it is nearly to d...
