Fix Any Coating Problem
Your equipment is failing, productivity is slipping, and your engineering team is getting anxious. Naturally, the coating takes the blame — but before you reach for a quick patch, step back and examine three interconnected properties of your machine design.
- Mechanical
- Corrosive
- Thermal
Choose any two, then add the third — because in most cases all three influence your overall system. When functional requirements turn out to be more demanding than anticipated, the properties of your current coating often no longer match. Will your new "toolbox of three" help you solve the coating problem?
Start With the Substrate
Begin by questioning the parent material. Does it deliver the mechanical properties you need? Failure may stem from elevated environmental temperatures, or from heat applied during the coating process. Either way, the stresses imposed on your substrate can be affected — along with a loss of dimensional or geometric stability.
Don't overlook surface roughness. Your ideal finish should encourage adhesion rather than unwanted interaction. Is your condition too abrasive? Hard coatings can be the right answer once toughness is properly understood — for instance, adding stiff layering through heat treat, nitrides, or carbon implantation may work well. Just keep your dynamic load and speed in mind.
Consider Corrosion and Your Next Coating
What about corrosion? Are higher temperatures part of the picture? Do you notice oxidation products, or is it purely a loss of mechanical property? Minimizing surface porosity can be essential.
So how about that new coating — have you found a better option? Remember to weigh its mechanical, corrosive, and thermal properties, and confirm each is compatible with both your substrate and your environment. Your "toolbox of three" will fix any coating problem. No plumber's tape required — we promise.
