TL;DR: In this paper, the influence of surface morphology, represented by roughness, on the corrosion and electronic behavior of copper was investigated using an atomic force microscope and a scanning Kelvin probe.

TL;DR: In this paper, the nanocrystalline surface layer of 304 stainless steel (304SS) produced using a sandblasting and annealing process was investigated using nano/micro/-indentation, micro-scratch, scanning Kelvin probe (SKP), potentiodynamic scanning and electrochemical scratch techniques.

TL;DR: The peak subsurface compressive residual stress produced by sandblasting was measured by XRD to be around 480 MPa as mentioned in this paper, and three distinct regions were observed in the sandblasted samples, namely severely deformed surface layer, the region deformed mainly by twinning, and the substrate.

TL;DR: In this paper, the tribological behavior and related properties of a nano-crystalline surface of 304 stainless steel (304SS) produced by a sandblasting and annealing process were investigated using micro- and nano-mechanical probes, a scanning Kelvin probe, an electrochemical system and a tribometer.

TL;DR: In this article, nanocrystalline and micro-crystalline copper deposits were produced by pulse and direct current electrodeposition processes respectively, and the effects of deposition parameters, such as the peak density, frequency, current-on time and current-off time of the pulse current (PC), on the grain size were investigated for the purpose of process optimization.
