Laser Surface Treatment

Fabrication of Nanostructured Omniphobic and Superomniphobic Surfaces with Inexpensive CO2 Laser Engraver

“…and the laser properties (e.g., laser focal spot size, temporal output profile etc.). 40,41,47,48 On the surfaces that are only omniphobic and not superomniphobic (i.e., stainless steel 304, titanium, aluminum, and glass), we postulate that the n-hexadecane droplets have Knowing that superomniphobicity is a strong function of surface chemistry, surface roughness, re-entrant texture, and breakthrough pressure from prior extensive work, 4,6,7,11,49,50 we have attempted to better identify (or eliminate) the possible parameters that are leading to the difference in wettability. We conducted X-ray photoelectron spectroscopy (XPS) to assess the surface chemistry for all the laser ablated and silanized surfaces.…”

Laser metal deposition materials-process-performance characterization studies

“…LMD is also known as Laser Cladding [12,13], Laser Direct Casting (LDC) [14], Direct Metal Deposition (DMD) by the University of Michigan [15], Directed Light Fabrication (DLF) by the Los Alamos national Laboratories [16], Laser Engineered Net Shaping (LENS) by Optomec [17]. Other known alternative names for LMD include laser powder deposition [18], direct laser powder deposition [19], and direct laser casting [20].…”
