Micro/nano scratch testing is an effective technique for characterizing the mechanical properties and wear resistance of materials. In practical applications, ... article, we develop a vibration-assisted micro/nano scratch tester. Its working principle is introduced, followed by ... Hz. To verify the feasibility of the proposed scratch tester, vibration-assisted scratch tests are performed on AL1050. It is shown that vibration during scratch testing leads to an increase in the residual scratch width and a decrease in the coefficient of ...

In this paper, a scratch-induced stress field model is built to analyze ... pyramidal, and spherical (CPS) indenters and correlates the scratch-induced principal stress with workpiece material properties, indenter geometries, and scratch behavior parameters (e.g., scratch normal load, tangential load, friction coefficient, scratch depth). With the model, the effects of scratch depth and indenter geometries on the scratch behavior and cracking behavior are investigated. The results ...

Although the deep learning-based scratch detection method boasts strong robustness, it is difficult to completely and accurately segment the scratch through this method. We, therefore, propose a scratch detection method combining deep learning and image segmentation algorithm to realize recognition and segmentation of scratches with low contrast and small size. To effectively ...

... In this study, a rotary ultrasonic vibration-assisted scratch (RUVAS) test was designed for the high-volume fraction of SiCp/Al composites. The kinematic and scratch force model of RUVAS was developed to describe the scratch process of SiCp/Al. Both RUVAS and conventional scratch (CS) tests were performed under various scratch speeds on SiCp/Al. The scratch trajectory was divided into three modes: continuous, semi- ... of different surface morphology under different modes. The scratch force difference between RUVAS and CS was insignificant ...
