... temperatures. The embedding process described in this paper consists of low temperature laser microdeposition of on-fiber silver thin films followed by nickel electroplating in a steel part. A microscale laser-based direct write (DW) method, called laser-assisted maskless microdeposition (LAMM), is employed...

... with an interlayer of nickel nanoparticles and compared with samples joined by conventional diffusion bonding and electroplated nickel-phosphorous diffusion brazing. Comparison is made with regard to microstructural evolution, diffusional profile, and bond strength. All bonding was carried out in a uni-axial vacuum...

... and modeling of pressure welding (solid state bonding) process are investigated, specifically for bonding of thin sheet metals. The effects of material type (e.g., copper, nickel, and stainless steel) and initial plate thickness ( 51 – 254 μ m ) as well as process conditions (e.g., welding pressure...

... laser pulses result in smoother surfaces. Results on microfabricated nickel samples using laser pulse durations of 300 ns and 650 ns test this hypothesis. Polishing with 300 ns and 650 ns pulse durations results in an average surface roughness of 66 nm and 47 nm, respectively; reductions of 30% and 50...

...Tyler L. Perry; Dirk Werschmoeller; Neil A. Duffie; Xiaochun Li; Frank E. Pfefferkorn The precision of parts created by microfabrication processes is limited by surface roughness. Therefore, as a means of improving surface roughness, pulsed laser micropolishing on nickel was examined numerically...
