Corrosion Factors

Corrosion Factors.The factors listed earlier have been organized in a framework of six categories with a number of subfactors as shown in the following Table.According to Staehle's materials degradation model,all engineering materials are reactive and their strength is quantifiable,provided that all the variables involved in a given situation are properly diagnosed and their interactions Corrosion Cells and Factors Causing CorrosionNature of the corrosive environment; Incidental environmental factors such as variations in the presence of dissolved oxygen,of temperature,and in the velocity of movement either of the environment or of the system itself; Other factors such as stress (residual or applied,steady or cyclic) Oxide scales (continuous or broken)Corrosion Cells and Factors Causing CorrosionNature of the corrosive environment; Incidental environmental factors such as variations in the presence of dissolved oxygen,of temperature,and in the velocity of movement either of the environment or of the system itself; Other factors such as stress (residual or applied,steady or cyclic) Oxide scales (continuous or broken)
