Top Tips For Corrosion Prevention in 2019

Your company’s method or methods of corrosion prevention in 2019 may not differ much from those used in 2018. Unless, that is, you haven’t been using thermal sprayed protective coatings on your parts, components, machinery, products, and other surfaces. Virtually every industry on the planet somehow benefits when thermal spray coatings are used. This is a far-reaching technological method of protecting multiple kinds of surfaces.

How will your company prevent corrosion in 2019? Here are a number of things to consider:

Can Everybody Get Along?

Material incompatibility is a definite consideration when thinking about using thermal spray coatings. Not all materials react the same in any given situation. When certain materials have dissimilar metal corrosion and come in contact with each other, they may be prone to oxidation. A less reactive metal must be put into contact with such materials.

Example: In a corrosive environment, aluminum and carbon steel should not be placed in contact with each other. Corrosion will be more likely to occur in this situation.

Prevent Corrosion with Protective Coatings

You can help guard underlying base materials against corrosion through protective coatings which limit the amount of oxygen that the base material comes into contact with. If an object is regularly subjected to ultraviolet or temperature exposure, these coatings can help there as well. Why spend money on corrosion resistant materials when you can affordably thermal spray surfaces with protective coatings?

Corrosion Rates and Geometry

The geometry or structure of a component can matter significantly where corrosion rates are concerned. Certain substances may collect in a localized area due to the shape of a material. Crevice corrosion could result within a sharp groove, for example, as a result of chlorine molecule buildup. When liquids pool or collect due to structural geometry, an accelerated rate of corrosion can result. Protective coatings help guard against this type of problem.

Environmental Concerns

While putting together a plan for corrosion prevention, one of the most important considerations is the environment in which your parts, machinery, components, etc. will spend the majority of their time. Certain environments are more prone to encourage corrosion than are others. Two perfect examples of this are as follows:

  • The acidic environment presented by underground soil.
  • Rich in chlorine saltwater that comprises a marine environment.

Without protection, surfaces will corrode in no time in these environments.

Residual and Applied Stress

One sure way of increasing the rate of corrosion is through stress. Fretting and other failures occur faster in corrosive environments when combined with dynamic stress. Stress corrosion cracking can affect static stress subjected materials as well. There are, in place today, proper design techniques that can disperse over a wide area (or significantly reduce) applied stresses.
