Image Denoising and Feature Extraction of Wear Debris for Online Monitoring of Planetary Gearboxes
IEEE Access, 2021 Wear debris generated in a pitting process of planetary gearboxes carries valuable information about health status. However, RGB images of online wear debris are often affected by image blur caused by Gaussian noise, high-frequency noise, and other ...

Induced-Pitting Behaviors of MnS Inclusions in Steel
High Temperature Materials and Processes, 2018 This paper investigated the effects of MnS inclusions on inducing pitting in steel. Three different cooling methods were used to control the morphology, size, and distribution of MnS inclusions. AC (alternating current) impedance spectroscopy experiments

Dynamic Precipitation during High‐Pressure Torsion of a Magnesium–Manganese Alloy
Advanced Engineering Materials, EarlyView.An ultrafine‐grained alloy is produced by high‐pressure torsion of solutionized Mg–1.35 wt% Mn. Precipitation of nanometer‐scale Mn particles during deformation provides pinning sites. This prevents the formation of a bimodal grain structure and results in a finer grain size than for pure Mg.

In Situ Diagnosis of a Gear-Tooth Surface Damage Using Laser Scattering
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2011 We propose herein an in situ method to remotely diagnose gear-tooth damage using scattering of a laser beam. The proposed method provides early and accurate diagnosis of the gear-tooth-surface condition.
