Abstract: A brake rotor having a composite structure may include an annular body defining opposite friction surfaces of the brake rotor. The annular body may include a core made of an Al—Si alloy, a thermal barrier layer made of a thermally insulating material disposed on the core, and a wear-resistant layer made of an Fe—Al—Si—Zr alloy disposed on the core over the thermal barrier layer. The wear-resistant layer may define a first one of the opposite friction surfaces of the annular body.

Abstract: A system for evaluating a battery cell includes an imaging device configured to take an image of at least part of the battery cell, and a processor. The processor is configured to perform: determining a region of interest in the acquired image, reducing a sharpness of the acquired image to generate a reference image, comparing the acquired image and the reference image, and identifying a discontinuity of the battery cell based on a difference between the acquired image and the reference image.

Abstract: A system for evaluating a battery cell includes an imaging device configured to take a first image of at least part of the battery cell when the battery cell is in a first deformation state, and take a second image of the at least part of the battery cell when the battery cell is in a second deformation state. The system also includes a processor configured to analyze the first image and the second image, identify a first region of the first image that represents a suspected discontinuity, the first region corresponding to a portion of the battery cell, compare the first region of the first image to a second region of the second image, the second region corresponding to the portion of the battery cell, and determine that the suspected discontinuity is an actual discontinuity based on a difference between the first region and the second region.

Abstract: A flash thermography device is configured to apply a flash of light to a target area on a surface of the battery cell. An imaging device is configured to capture an image of the target area subsequent to the flash of light being applied to the surface of the battery cell. A defect detection control module is configured to receive the image captured by the imaging device, analyze the image to determine whether a defect is present in the battery cell, and selectively generate and output an indication of whether the defect is present based on the analysis of the image.
