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.

Digital terrain modelling and industrial surface metrology — converging crafts
TL;DR: This paper introduces terrain modelling and compares it with metrology, noting their differences and similarities and one of the many issues common to both disciplines.

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 measurement of three-dimensional strains around a creep-crack tip
TL;DR: In this article, a new method for measuring the strain around the high-temperature creep-crack tip is proposed, where a grid pattern was described in a space of about 30 μm with a diamond stylus in the area ahead of the precrack of the specimen, and the distortion of the grids and the change in specimen thickness were measured by means of a photo-microscope and a roughness-measuring system, respectively.

Surface Smoothing Mechanism by Replication in Ironing Process
Zhrgang Wang,K. Kondo,T. Mori +2 more
TL;DR: In this article, an internal ironing apparatus was developed to observe the surface during the processing and it was shown that the surface smoothing process is largely developed during a very short contact length from the entrance of the contact zone where the bulk material is in the elastic state and can be markedly promoted by the plastic deformation in the surface layer.

Lubrication of cylindrical rollers with surface corrugations
Kristian To̸nder,H. Christensen +1 more
TL;DR: In this paper, the authors show how the wavelength of corrugations on a cylindrical roller strongly influences its hydrodynamic properties and how these properties tend towards those obtained by the authors' probabilistic roughness theory.

Cl2‐Based Dry Etching of GaAs, AlGaaAs, and GaP
TL;DR: In this article, the etch rates for all three materials increase with radio frequency (RF) and microwave power, plasma composition, mask material, and process pressure, with controlled rates of approximately 0.4 m/min at a condition of 2Cl{sub 2}/13Ar, 850 W microwave power and 1.5 mTorr, and 100 to 150 W of RF power.
