What kind of tool can measure a polarization curve in coulombs per second?
The tool used to measure a polarization current (1 amp = 1 coulomb per second) is called a potentiostat. A potentiostat is an essential device used in corrosion studies...
Does aluminum rust?
We often use the term "rust" to mean corrosion, but these two terms do not mean the same thing.Distinguishing between Rust and CorrosionRust is a coating that...
Will using wet abrasive blasting instead of dry eliminate dust?
Firstly, before we answer this question it is important to clear up a common misconception. There is no such thing as a 100% dustless surface preparation method. (For...
What do I need to consider when it comes to applying high solids coatings?
High solids coatings can offer numerous advantages when compared to solvent-based coatings. Some of these advantages include better durability, faster drying times and...
How can you avoid flash rust during wet blasting?
Flash rust is defined as the corrosion that occurs on the surface of a metal shortly after any wet method of surface preparation. This type of rusting typically occurs...
