Degradation Of Metals Polymers And Ceramics

Either materials loss by dissolution corrosion or formation fo a non metallic scale oxidation.

Degradation of metals polymers and ceramics.

Oxidative degradation is usually initiated when polymer chains form radicals either by hydrogen abstration or by homolytic cleavage of a carbon carbon bonds. May dissolve or absorb and swell when exposed to liquid. The degradation of a polymer can be induced by light heat and oxygen and can be greatly accelerated by stress and exposure to other chemicals. Ceramic materials arerelatively resistant to deterioration which usually occurs at elevated temperatures or in rather extreme environments.
