Annually, companies lose a substantial sum of their profits to corrosion. Mitigating the problem to ensure the machinery continues to operate optimally can be a problem. While some companies spend significant sums fighting it after the fact, the more sensible approach is to utilize a lubricant containing a corrosion inhibitor additive.
The Preventive Approach
Corrosion can be inhibited before it occurs. Anti-corrosion coatings are one method of accomplishing this. However, the most effective or efficient method in metalworking equipment – where parts actively meet creating friction – is the use of an enhanced lubricant.
Among the more common additives is one that decreases the ability of a metal to corrode and rust. This corrosion inhibitor additive may provide protection in one of several forms. Three common types are:
- Anodic Inhibitors: These provide an oxide film over the metal base’s surface to protect it. Common examples include chromates, molybdates, nitrates and tungstate
- Cathodic Inhibitors: This type of corrosion inhibitor additive reduces the process of corrosion by slowing down the cathodic reaction. Specific types of cathodic inhibitors are cathodic poison and oxygen scavengers
- Mixed Inhibitors: This combines the best of both anodic and cathodic inhibitors. These inhibitors form a film on the base metal surface to reduce reactions. Examples include silicates and phosphates
Prevention Not Reaction
It is better to stop corrosion before it occurs. Talk to the professionals about what type of corrosion inhibitor additive will perform best. This preventive approach is the best strategy to adopt. It reduces costs and ensures continuing production.
