CORROSION PREVENTION AND CONTROL (CPC)
Corrosion Prevention and Control (CPC) of Army materiel is a continuing concern. It is important that any
corrosion problems with this item be reported so that the problem can be corrected and improvements can
be made to prevent the problem in future items.
Corrosion specifically occurs with metals. It is an electrochemical process that causes the degradation of
metals. It is commonly caused by exposure to moisture, acids, bases, or salts. An example is the rusting of
iron. Corrosion damage in metals can be seen, depending on the metal, as tarnishing, pitting, fogging, surface
residue, and/or cracking.
Plastics, composites, and rubbers can also degrade. Degradation is caused by thermal (heat), oxidation
(oxygen), solvation (solvents), or photolytic (light, typically UV) processes. The most common exposures are
excessive heat or light. Damage from these processes will appear as cracking, softening, swelling, and/or
breaking.
SF 368, Product Quality Deficiency Report should be submitted to the address specified in DA PAM 750-8,
The Army Maintenance Management System (TAMMS) Users Manual.
