Nano-impact is fast becoming a valuable tool in the development of coatings for longer-life in high-speed machining and for greater productivity in machining hard-to-cut materials for the aerospace and automotive industries. Key features of the nano-impact technique:
- Allows rapid quantitative results to replace time-consuming field trials and provides higher surface sensitivity than bulk impact tests.
- Extends nanomechanical testing to much higher strain rates so that strain rate sensitivity can be studied over a wider and more practically useful range.
- Evaluates damage tolerance and fatigue resistance of thin films to multiple high energy density impacts.
