In-process fast surface measurement using wavelength scanning interferometry [PDF]

open access: yes, 2012
A wavelength scanning interferometry system for fast areal surface measurement of micro and nano-scale surfaces which is immune to environmental noise is introduced in this paper. It can be used for surface measurement of discontinuous surface profiles

Comparison of fast Fourier transform and convolution in wavelength scanning interferometry [PDF]

open access: yes, 2011
The assessment of surface finish has become increasingly important in the field of precision engineering. Optical interferometry has been widely used for surface measurement due to the advantages of non-contact and high accuracy interrogation.

Study on the Friction Characteristics and Fatigue Life of Manganese Phosphate Coating Bearings

open access: yesLubricants, 2023
In this study, the tapered roller bearing was adopted to explore the effect of the manganese phosphate coating on the friction, wear, and lifespan of bearings. Line friction samples with and without a manganese phosphate coating were prepared.

Dispersed reference interferometry

open access: yesCIRP Annals, 2013
Abstract Dispersed reference interferometry (DRI) is a potentially useful technique for applications such as absolute displacement, surface topography and film thickness measurement. A bulk optic implementation of a short coherence dispersed reference interferometer is described with the chromatic dispersion applied using two matched transmission ...

ZDDP Tribofilm Formation from a Formulated Oil on Textured Cylinder Liners

open access: yesLubricants, 2022
Surface texturing can improve lubrication and entrap wear debris but increases the effective roughness of the surfaces, which can induce higher contact pressures.
