Optical Characterization of Transfer Film Mechanics
| Transfer films are effective mediums for enhancing surface properties such as friction performance, oxidation protection, wear resistance, electrical conductivity etc. However identifying the governing mechanics behind their operation remains a top priority in optimizing their performance. This project centers around identifying these mechanics through intuitive investigations of the transfer film before and after usage. Current examples include determining the mechanics of deposition and depletion for solid lubricant transfer films, measuring oxidation resistance from anti-oxidant additives, and establishing wear life based on in situ optical microscopy.
