Case Study of NASA Webb Telescope via Ferrography and More

Ferrography has been around since the 1970’s invented by Vernon Westcott due to a need to observe wear particles/Ferrography in the 5–350-micron range. Most believe this is the particle size range to detect potential failure prior to any mechanical problems. However, the ferrography analysis was thought to be time consuming, expensive, and non-repeatable.
