WASHING AGENT INFLUENCE ON ALUMINUM ALLOYS
This paper is a study layer of aluminium and aluminium alloys, subjected to the action of external self-detergents, and their behaviour in processes of wear or fatigue. The data obtained are useful in the analysis of structural changes that appear and develop during the destructive processes mentioned. The study of structural changes can be made by various non-destructive techniques, which occupied an important place of composition applied to the alloys washing agents, working environment and temperature.

INFLUENCE ON ACTIVE FOAM LAYERS OF METAL
This paper aims to achieve a bibliographical study and practical research on technologies for coating metal layers, especially nickel-based alloys and their use in automotive and foams active influence on them in the wash. It was found that with the wear caused by aging and external factors, including repeated washing, auto parts nickel, shows a frosting, that glossy look is diminished, so is looking for a foam manufacturing assets that do not affect the optimal structure of material basis of their physical properties.
