The effect of environment on automotive materials / Azizah Hj Ali Sibramulisi

The degradation of metals in natural environment is a continuing process by which metals and their alloys, plastics and polymers, glass and ceramics, composites, are returned to their lower energy-level states. This oxidation process is normally referred to as corrosion and is the result of the interaction of a metal with its environment. With increasing concern as to the availability of automotive materials, more emphasis is expressed in the corruption of the materials exposed to corrosive atmospheres. Atmospheric corrosion is one of the principal causes of economic losses in the automotive, construction, machinery, shipbuilding, recreation, and other industries. This report represents the contents of atmosphere and its effects to automotive materials. Many kinds of effects were found. We had analyses all the effects from our industrial visits and surveys all around urban and non-urban area, and coastal area. Then we discuss the solution to all the problems and why it's happen. After that we came with conclusions from our observations. I hope that this report can be a reference for our new generation as a guidance to deal with these effects. I also hope that this report meets the needs of the students and research engineer, so that it will serve its purpose.
