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. Oxidative degradation is usually initiated when polymer chains form radicals either by hydrogen abstration or by homolytic cleavage of a carbon carbon bonds. This process is frequently also called.

Corrosion and materials degradation issn 2624 5558 is a peer reviewed open access journal published quarterly by mdpi. Loss of massin metals and alloysis called corrosionor the formation of nonmetallic film оn the surface of metalsis called oxidation. Manuscripts are peer reviewed and a first decision provided to authors approximately 20 5 days after submission. Deterioration at high temperature or extreme environments corrosion.

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.
