A simple numerical model of the apparent loss of eddy current conductivity due to surface roughness
In light of its frequency-dependent penetration depth, the measurement of eddy current conductivity has been suggested as a possible means to allow the nondestructive evaluation of subsurface residual stresses in shot-peened specimens. This technique is based on the socalled electro-elastic effect, i.e. the stress-dependence of the electrical conductivity. Unfortunately, the relatively small ch...
متن کاملInfluence of Surface Roughness on Results of XPS Measurements
A concise overview of methods estimating the effect of surface roughness on results of XPS measurements is given. Tilt-angle histogram method (THM), straight-line approximation (SLA) and Monte Carlo (MC) simulations are considered. An application of such methods is described in detail in the case of flat and artificially corrugated silicon surfaces.
متن کاملInfluence of Nanoscale Surface Roughness on Colloidal Force Measurements.
Forces between colloidal particles determine the performances of many industrial processes and products. Colloidal force measurements conducted between a colloidal particle AFM probe and particles immobilized on a flat substrate are valuable in selecting appropriate surfactants for colloidal stabilization. One of the features of inorganic fillers and extenders is the prevalence of rough surface...
متن کاملIn situ non-contact measurements of surface roughness
Surface roughness measurements are often required to validate a machining process. However, when using a 3D surface roughness measuring instruments it is usually necessary to remove the part from the machine tool between two operations, potentially introducing systematic errors. Furthermore, surface roughness measuring instruments are not suited for measuring heavy and large parts such as stamp...
متن کاملDynamic Piezoresistivity Calibration for Eddy Current Nondestructive Residual Stress Measurements
It has been recently demonstrated [M. P. Blodgett and P. B. Nagy, J. Nondestruct. Eval. 23, 107 (2004)] that eddy current conductivity measurements can be exploited for near-surface residual stress assessment in surface-treated nickel-base superalloy components. To quantitatively assess the prevailing residual stress from eddy current conductivity measurements, the piezoresistivity coefficients...
