Abstract
The salt deposits of Ohio possess high grades of salt and have been actively mined since the industry began in the late eighteenth century. Corrosion of metals used in the construction of salt mining equipment has always been an extremely important problem . Even minimal amounts of corrosion may effect operation procedures and product purity. Additional costs are required for maintenance and replacement of corroded parts. The development of various iron and aluminum alloys used for construction materials has drastically reduced the amounts of corrosion in most mining operations. When metal such as magnesium and manganese are added to aluminum, the corrosion resistant properties are greatly increased. Iron containing nickel and copper, and stainless steel containing chromium, nickel, and molybdenum, possess increased corrosion protection abilities. Techniques used for surface protection such as cladding, cathodic protection, painting, and inhibiting are often successful in combating corrosion.
