Role of Scanning Electron Microscopy in the Automotive Industry
One of the primary uses of SEM in the automotive industry is for quality control and failure analysis. SEM can be used to identify defects and structural abnormalities that may affect a material’s mechanical properties. For example, SEM can be used to find cracks, porosity, and corrosion in metals and alloys.
Deep Learning-Based Defect Classification and Detection in SEM Images
2022年6月20日 · The proposed ensemble method demonstrates improvement of the average precision metric (mAP) of the most difficult defect classes. In this work we have developed a novel robust supervised deep learning training scheme to accurately classify as well as localize different defect types in SEM images with high degree of accuracy.
Interpreting Images from Scanning Electron Microscopy
The scanning electron microscope (SEM) is a powerful materials characterization tool capable of taking high-magnification and high-resolution images[1]. The SEM generates high-energy primary electrons and focuses them into a tight beam, which is then rastered upon a material surface.
Scanning Electron Microscopy (SEM) Analysis and Imaging
Scanning electron microscopy (SEM) or SEM analysis is a powerful analytical technique to perform analysis on a wide range of materials, at high magnifications, and to produce high resolution images. TWI’s extensively equipped electron microscopy suite allows many different types of sample to be analysed, giving resolution greatly exceeding ...
