Surface degradation of micro-mold in micro-scale laser dynamic forming and its effects on workpiece
Optics & Laser Technology(2019)
摘要
•The surface degradation of micro-mold in μLDF is first investigated.•The surface degradation is the gradual failure due to the regular forming operation.•Laser shock wave can realize micro-coining on metal surface.•Laser shock target experiments are performed to explore the degradation evolution process.
