Corrosion in Exhaust Systems.Vol-1:

The exhaust system of an automotive muffler has lots of prerequisite to accomplish. The foremost one is to reduce the noise level produced by the engine, adequate insertion loss, to access the waste gases out from the rear part of automobile system, to play down the reduction in engine performance, to have a satisfactory service life, back pressure, shape, style, and cost (1).

Corrosion in Exhaust Systems.Vol-2:

Aluminum-plated or aluminized steel has been used in the exhaust system of vehicles, which exhibits a corrosion resistance higher than that of carbon steel in the exhaust gas condensate environment in automotive muffler and shows excellent resistance to oxidation as well for application in high temperature environments. Various aluminizing processes have been developed, such as laser aluminizing, electro spark depositing, vacuum plasma spraying and gas phase aluminizing. Hot dip aluminizing is one of the most economical techniques for aluminizing steel surfaces.Read More
