Abstract

The invention relates to the field of high-precision apparatuses and concretely relates to a high-precision instrumented indenter system. The system comprises a driving device, a load measurement system, a displacement measurement system, a computer control system, a data automatic processing system, an indenter assembly and a frame. The frame is provided with the driving device. The driving device is connected to the data automatic processing system through the computer control system. The driving device is connected to the load measurement system. The load measurement system is connected to the indenter assembly through the displacement measurement system. The driving device and the load measurement system are separated so that the test load on the indenter can be measured accurately and it is avoided that an integrated design of the driving and load measurement causes thermal drift of load basic data measurement. The high-precision instrumented indenter system solves the problem that the existing sample reference-type indenter cannot accurately detect indenter pressing depth displacement because of small-angle inclination of a sample surface in pressing.

Description

technical field [0001] The invention relates to the field of high-precision instruments, in particular to a high-precision instrumentation indenter system. Background technique [0002] With the rapid development of surface modification materials, thin film / coating materials, composite materials, nanomaterials and other fields, instrumented pressing technology has been more and more popular because of its unique role in the field of surface material science and engineering research. people's attention. This technology continuously and synchronously tests and records the load-displacement relationship of a diamond indenter with a specific geometry in the process of indenting and evacuating the sample, providing much more valuable information than traditional hardness tests that can reflect the mechanical properties of the tested material. By building a fine mechanical model and with the help of large-scale finite element numerical analysis software, many basic mechanical per...
