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.

Degradation of metals polymers and ceramics.

Deterioration at high temperature or extreme environments corrosion. Loss of massin metals and alloysis called corrosionor the formation of nonmetallic film оn the surface of metalsis called oxidation. Degradation mechanisms the properties of the aluminum alloys titanium alloys nickel based superalloys polymer matrix composites and ceramic matrix composites that are candidate materials for hsct high speed civil transport structures and engines may degrade with time at the elevated temperatures associated with the operation of the aircraft. 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. Either materials loss by dissolution corrosion or formation fo a non metallic scale oxidation.
