hybrid beads were fabricated for the analysis of the layering effects between them. From these studies, the effects of the processing parameters, such as laser power, scan rate and scan line spacing... and a maximum power of 200 W in an argon or nitrogen gas environment was used. In the DLM process, a powder layer was deposited onto the substrate, which was attached to the build cylinder. The laser beam......

for test surface of Si3N4 bars Two continuous wave (CW) carbon dioxide (CO2) lasers were applied for surface treatment. An 80 W CO2 laser (L80A, Laser Machining Inc.) was used for low power density treatments, a 1.5 kW CO2 laser (Model 820, Rofin-Sinar?) for intermediate and high power density treatments. A 25.4 mm diameter plano-convex cylindrical lens (effective focal length 127......
with a laser power of 95 W for both the bulk of the sample and the contour. The laser scanning speed was 650 mm/s for the bulk and 850 mm/s for the contour. A layer thickness of 30 μm was used with a laser spot... J. Cent. South Univ.
