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.
SF Form 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.
