Most metallic corrosion is a destructive electrochemical attack while polymeric degradation is physiochemical (physical + chemical phenomena). Metals can be attacked by aqueous based corrosion or oxidised at elevated temperature. Exposure to temperatures that are sufficient to cause bloating, melting, or vaporization can change it’s form. Mechanisms of Deterioration: These depend on the type of material: Metals : Either materials loss by dissolution (corrosion) or formation fo a non-metallic scale (oxidation). Chemical degradation of soils is a consequence of the post-Industrial Revolution.
Key parameters. Almost nothing. In the energy sector high temperature corrosion of metals due to oxidation, sulfidation, carburization and metal dusting is a major concern. DOI: 10.1016/j.wasman.2011.12.002. The average period from submission to first decision in 2018 was 30 days, and that from first decision to acceptance was 30 days.
Changes in properties due to the interaction (mechanical – ductility or strength, physical properties, or appearance). Key parameters of the project include:
change in chemical properties of the polymer.

Protection of Metals and Physical Chemistry of Surfaces is a peer reviewed journal. 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. Environmental Degradation of Metals.

The project investigates the degradation of high alloyed materials and coatings at temperatures above 1000°C under oxidation conditions.
And unlike corrosion of metals, the ways you can destroy a polymer are also great in number and plentiful in variety :p
In the energy sector high temperature corrosion of metals due to oxidation, sulfidation, carburization and metal dusting is a major concern. The main there aspects of chemical degradation of polymers which are as under:

The project investigates the degradation of high alloyed materials and coatings at temperatures above 1000°C under oxidation conditions. Cathodic area, the driving force for the corrosion process. Scattered literature is harnessed to critically review the possible sources, chemistry, potential biohazards and best available remedial strategies for a number of heavy metals (lead, chromium, arsenic, zinc, cadmium, copper, mercury and nickel) commonly found in contaminated soils. Probing the Water Stability Limits and Degradation Pathways of Metal–Organic Frameworks Mohamed E. A. Safy Center for Materials Science, Zewail City of Science and Technology, October Gardens, Giza, 12578 Egypt This is a complex process with same end result i.e. Electrolyte to transport corrosive species and various ions.

Most of the research work on recovery of recycled materials is focused on the two deficiencies.
Environmental chemicals may react with constituents of the wood to cause degradation, particularly strong acids or alkalis or the decomposition of another material leading to the introduction of decompositional bacteria and other organisms.
