| Abstract Scope |
The optical reflectance limits the number of materials that laser-based sintering techniques can process. In this work, the optical properties of Ti, Al, Ni, and Cu powders are tailored by vibration-assisted magnetron sputtering with Cu and Cr shells. Optical emission spectroscopy was used to measure the reflectance of the raw and modified powders from infrared to ultraviolet. The film conformality and thickness were then measured using a focused ion beam and scanning electron microscopy. Sintering tests of the modified powders show that surface modification is a promising tool to improve the material availability for laser-based sintering techniques. |
