Yesterday, I shared a thermal image from the Fluke Ti20 Thermal Imager. The thermal image is a great way to identify "hot spots" in a process. In particular, I am searching for areas that could lead to the desorption of azole-type corrosion inhibitors from metallic surface. Generally speaking, these types of inhibitors can form bonds with the metallic surfaces to reduce corrosion and oxidation. At elevated temperatures, some research suggests that they will come off of the surface and leave the surface susceptible to corrosion.
Some new questions:
1. Okay, so I am in search of a specific temperature that I have found in the literature. How much does exposure time come into play? In other words, will the species desorb at lower temperatures with more lengthy exposure?
2. What is causing variation between components and machines? Mechanical differences? electrical differences?
