Abstract

The invention discloses an in-situ micro-nano indentation/scratch test platform, and belongs to the technical field of test platforms. The in-situ micro-nano indentation/scratch test platform comprises a coarse adjustment device, a fine adjustment device and a transmission device; the coarse adjustment device comprises a base, an angle scale and a workbench; the angle scale is slidably connected to the top of the base through a precision slide rail; the workbench is slidably connected to the top of the angle scale; and a first turbine is fixedly mounted in the middle of the angle scale. According to the in-situ micro-nano indentation/scratch test platform, through the coarse adjustment device and the fine adjustment device, the test platform has the advantages of compact structure and high precision; through the matched arrangement of a first hand wheel and a fine adjustment knob, high-precision adjustment of sample positioning can be realized in the use process, angle and multi-directional test is realized, and therefore, the application range is widened, the practicability of the device is improved; the test platform is compact in structure and just occupies small space; and the test platform has the advantages of large stroke, high precision and compact structure.

Description

technical field [0001] The invention relates to the technical field of test platforms, in particular to an in-situ micro-nano indentation / scratch test platform. Background technique [0002] With the development of science and technology and the advancement of electron microscopy technology, the application of in-situ micro-nano mechanical testing technology has emerged. The significant advantage of in-situ indentation / scratch testing technology is that it can realize real-time online observation of the indentation / scratch process, and then study the deformation and damage mechanism of the material surface under load. The research on in-situ testing of mechanical properties of materials at home and abroad is still in the stage of development and exploration, but due to the early start in developed countries, the research is relatively in-depth, ahead of domestic research in this field. In terms of in-situ mechanical testing, typical tests include microcolumn compression, mi...
