The properties of aluminum and its alloy make them to be the first choice as manufacturing materials for different equipments and accessories. The light weight, high strength and improved corrosion resistance recommend aluminum and its alloy to be used specially in transportation and construction industries. The native aluminum oxide film formed after exposure in air presents voids and cracks and the exposure aluminum parts to corrosive environments which lead to the degradation and reducing their lifetime. In ord...

1050 aluminum alloys are used in the conventional engineering applications where the increased corrosion resistance is required (e.g. automotive industries or construction, containers). Improving the corrosion resistance of 1050 aluminum alloy is an extensively studied topic. Different methods are applied to improve the corrosion resistance of 1050 aluminum alloy as: painting, waxing, zinc-chromate priming, thin layer of pure aluminum, coatings with a liquid protective solution, conversion coatings and also anodic...

The loss of an organ or part of an organism generates, in addition to loss of function, social and psychological disorders. The modern bio-technologies try to diminish their effects on affected humans. The advancement of modern medicine that uses biomaterials to solve issues related to tissues and organs reconstruction has increased the human life expectancy, rapidly. The most important factors that limit the lifetime of implants are certain corrosion and wear products, which can have negative effects on the human...

Corrosion is the deterioration of a metal as a result of chemical reactions between it and the surrounding environment. Is a natural process, which converts a refined metal to a more chemically-stable form, such as its oxide, hydroxide, or sulfide. It is the gradual destruction of materials (usually metals) by chemical and/or electrochemical reaction with their environment. Biomaterials are used to replace a part of the body functions lost due to illness or to improve functions and to correct anomalies. The import...
