EFFECT OF SHOT-PEENING ON THE FATIGUE STRENGTH OF SPRING STEEL AFTER EXPOSURE TO CORROSION

摘要

Corrosion is a process which can be neither retarded, nor glossed over. Over a shorter or longer period of time corrosion destroys the majority of objects which are made by man, regardless of the material from which they are made. There are numerous methods and technologies for protecting the surfaces of metallic objects most often by depositing on them or forming of coatings or layers which block the direct action of corrosive environments, for minimizing or eliminating surface or volume corrosion. It is known that residual compressive stresses which can be generated by various manufacturing and other technological processes will be conducive to a rise of longevity of mechanically loaded components working in a corrosive environment [1].
