Methods to eliminate corrosion

Methods to reduce the sulfur, chloride, or oxygen content in the surrounding
environment can limit the speed of metal corrosion. For example, feed water for water
boilers can be treated with softeners or other chemical media to adjust the hardness,
alkalinity or oxygen content in order to reduce corrosion on the interior of the unit.
Metal Selection and Surface Conditions
No metal is immune to corrosion in all environments, but through monitoring and
understanding the environmental conditions that are the cause of corrosion, changes
to the type of metal being used can also lead to significant reductions in corrosion.
Metal corrosion resistance data can be used in combination with information on the
environmental conditions to make decisions regarding the suitability of each metal.
The development of new alloys, designed to protect against corrosion in specific
environments, is constantly under production. Hastelloy nickel alloys, Nirosta steels,
and Timetal titanium alloys are all examples of alloys designed for corrosion prevention.
Monitoring of surface conditions is also critical in protecting against metal deterioration
from corrosion. Cracks, crevices or asperous surfaces, whether a result of operational
requirements, wear and tear, or manufacturing flaws, all can result in greater rates of
corrosion.
