Demonstration of Wear Monitoring of Amorphous Carbon Films with Epoxy Resin Underlayer Containing Phosphor

A concept of wear monitoring of tribological coating has been proposed and extended to monitor the wear life of amorphous carbon (a-C) films. The wear sensing layer that is an epoxy resin coating containing luminescent ZnS:Cu powder (EP/ZnS:Cu) is located between a-C film and silicon wafer substrate...

The wear sensing layer that is an epoxy resin coating containing luminescent ZnS:Cu powder (EP/ZnS:Cu) is located between a-C film and silicon wafer substrate.
