  • Method for testing interfacial tribochemical reaction between abrasive and diamond wafer
    Patent number: 11982650
    Abstract: A method for testing an interfacial tribochemical reaction between a diamond wafer and active metal abrasive or metal oxide abrasive is provided. A surface of a diamond indenter used in a nano scratch tester is coated with a layer of the active metal abrasive or the metal oxide abrasive with uniform and controllable thickness by magnetron sputtering, and an interface interaction between the layer of the active metal abrasive or the metal oxide abrasive and the diamond wafer is controlled by a scratch test of the diamond wafer. Chemical components of an interaction section on a surface of the diamond wafer are analyzed by the scanning probe micro Raman spectrometer.
