Nanosecond-Pulse Laser Assisted Cold Spraying of Al–Cu Aluminum Alloy
In this study, nanosecond-pulse laser is used in combination with cold spraying to form a hybrid solid-state forming technology: nanosecond-pulse laser assisted cold spraying. This method successfully manufactured Al-Cu high-strength aluminum alloy coatings. The nanosecond-pulse laser reduced the po...
