Surface roughness measurement by means of speckle wavelength decorrelation
M. Giglio,S. Musazzi,U. Perini +2 more
TL;DR: In this article, the authors exploit speckle wavelength decorrelation techniques for the characterization of surface roughness up to a few microns, using an argon laser, a grating, two photodetectors, and a commercial cross correlator.

Digital Terrain Modeling and Industrial Surface Metrology: Converging Realms
TL;DR: In this article, the authors introduce industrial surface metrology, examines the field in the context of terrain modeling a.k.a. surface topography of manufactured components, exemplified by automobile-engine cylinders, is routinely modeled by variogram analysis, relief shading, and most other techniques of parameterization and visualization familiar to geography.

Interdependence of Amplitude Roughness Parameters on Rough Gaussian Surfaces
TL;DR: The numerical analysis of 17 standardized amplitude roughness parameters collected from 90000 computer-generated rough surfaces revealed so far undetected interdependencies among some of these parameters, namely the results show a strong linear relation between 12 amplituderoughness parameters.

Nano-metrology and terrain modelling - convergent practice in surface characterisation
TL;DR: In this paper, the authors introduce terrain modelling, discuss its similarities to and differences from industrial surface metrology, and raise the possibility of a unified discipline of quantitative surface characterisation, and exemplify a multivariate statistical procedure that may transfer to tribological applications of 3-D metrological height data.

A procedure for achieving single crystal-like zirconia particles
TL;DR: In this article, an improvement of a previously reported procedure aimed at obtaining pure phase monoclinic zirconia powders was presented, by modulating duration and alternation of mechanical and firing treatments, which determined the formation of single crystal, smooth particles, with regularly coordinated surface cations.

Phase shift of the reflection coefficient of ultrasonic waves in the study of the contact interface
J. Królikowski,J. Szczepek +1 more
TL;DR: In this article, the phase shift of the coefficient of reflection at the contact interface between ground steel samples and quartz samples was measured and compared with the results of the theoretical model of contact of rough surfaces.

Mass transfer at rough gas-sparged electrodes
TL;DR: In this article, the authors measured the rate of mass transfer at a smooth and rough inner surface of an annular gas sparged cell in the bubbly regime using the limiting current technique.

Hydraulics of Stationary Capsule in Pipe
Henry Liu,James L. Richards +1 more
TL;DR: In this article, the authors predict the variation of pressure along a single cylindrical capsule resting on the bottom of a pipe by using the one-dimensional energy equation, the momentum equation, and the continuity equation with proper consideration for the head losses including entrance and exit effects, as well as using experimental values of the energy correction factor α and the momentum correction factor β of the eccentric annular flow around the capsule.

Specular reflectance of cold-rolled aluminum surfaces
Raimo Silvennoinen,Kai-Erik Peiponen,Toshimitsu Asakura,Yan-Fang Zhang,Cong Gu,K. Ikonen,E. J. Morley +6 more
TL;DR: In this article, the specular reflectance of cold-rolled aluminum surface is studied using a fiber optic system and an approximation for the determination of surface roughness is presented. But the results are limited.
