Corrosion is the destructive result of reaction between a metal or metal alloy and its environ‐ ment [1-3]. Metal atoms in nature are present in chemical compounds (i.e, minerals). The same amounts of energy needed to extract metals from their minerals are emitted during the chemical reactions that produce corrosion. The corrosion process (anodic reaction) of the metal dissolving as ions genera...

The introduction of copper as wire bonding material brings about a new challenge aluminum bond pad bimetallic corrosion at the copper/aluminum galvanic interface. Aluminum is well known to undergo pitting under halide-contaminated environments, even in slightly acidic conditions. This paper aims study morphology and progression influenced by different halide contaminations presence absence cont...

We show that acetone-derived graphene coating can effectively enhance the corrosion efficiency of copper (Cu) in a seawater environment (0.5-0.6 M (∼3.0-3.5%) sodium chloride). By applying a drop of acetone (∼20 μl cm(-2)) on Cu surfaces, rapid thermal annealing allows the facile and rapid synthesis of graphene films on Cu surfaces with a monolayer coverage of almost close to ∼100%. Under optim...

Cupronickel 90/10 alloy has been used world wide as a standard material in heat recovery tubes. The alloy exhibits excellent service characteristics and can also withstand flow up to 3.3 m / sec of seawater. This alloy (Cupronickel, 90/10) was used in the construction of Jeddah IV heat recovery section of desal condenser tubes. Jeddah IV desal unit has 4 modules, each module consists of 21 stag...

We study copper corrosion inhibition by ethanolamine (ETA)with (0, 0.2 ,0.3,0.4,0.5) vol.% concentrations in 100 ppm NaCl solution. This work is carried out by potentiodynamic measurements and Electrochemical Impedance Spectroscopy (EIS). The substrates' surface morphologies are examined by Scanning Electron Microscopy (...

The new electrical conductive material, copper alloy, C194 in situ composite, has been developed for the application to leadframe, high field magnet and trolley wire. This material has a low cost, high thermal and electrical conductivity, easy fabrication and joining, and also has a wide range of attainable mechanical properties. In C194, copper is one of the core materials in producing leadfra...

This paper presents the results of study that was undertaken to investigate the ability of a new antiscale, polyacrylamide in solving problems found in cooling water systems. The effects of the polymer on C-steel and copper dissolution in synthetic cooling water environment were studied through scale, Tafel, and Linear polarization measurements. The results obtained from this study showed that ...
