Description

technical field [0001] The present invention relates to a portable scratch-in testing system. Background technique [0002] Instrumented indentation is a microscale mechanical testing system. This type of instrument can automatically and real-time measure and record the load acting on the indenter and the depth of the indented sample during the indentation test cycle. Using load-depth and other information, through inversion analysis, the indentation hardness and indentation of the material can be identified. mechanical parameters. The indentation instrument is an indentation instrument with expanded functions. During the indentation process, the driving indenter and the sample generate horizontal relative motion, and simultaneously measure the continuous changes of horizontal load, vertical load and indentation depth with the indentation position. process. Not only can the friction and wear, deformation and damage properties of materials and structures be studied, but al...
