Problems solved by technology

The XPS method can detect extremely thin coating thickness with high precision, but has the disadvantages of slow detection speed (the maximum depth of each etching is generally only 50nm), high cost, and can only detect the coating thickness of local micro-areas.
The TEM method first needs to cut a cross-section of titanium-coated diamond particles through a focused ion beam (FIB), and then observe the coating thickness on the surface of the sample. The sample preparation process is complicated and the test cost is extremely high.

Abstract

The invention relates to a method for detecting the thickness of the coating on the surface of titanium-coated diamond particles. The specific steps are: 1. Ultrasonic cleaning is performed on the titanium-coated diamond particles, and drying is performed after removing oil stains; 2. A certain quality of titanium-coated diamond particles is weighed by a balance Place in dilute sulfuric acid solution, corrode the Ti layer, clean and dry the diamond particles after the corrosion, and weigh the diamond particle quality; 3. place the titanium-coated diamond particles obtained in step 2 in dilute nitric acid solution, corrode the TiC layer, After the corrosion is over, clean and dry the diamond particles, and weigh the quality of the diamond particles; 4. By removing the Ti layer and the TiC layer on the surface of the diamond particle, calculate the weight of the Ti layer and the TiC layer on the surface of the titanium-coated diamond particle according to the calculation model. thickness. The method for detecting the thickness of the coating layer on the surface of the titanium-coated diamond particle has simple process and low cost, and can quickly and accurately detect the average thickness of the Ti layer and the TiC layer on the surface of the titanium-coated diamond particle prepared by various methods.

Description

technical field [0001] The invention belongs to the technical field of diamond particle surface treatment, and in particular relates to a detection method for the thickness of a TiC layer and a Ti layer on the surface of a titanium-coated diamond particle. Background technique [0002] Diamond is the hardest substance in nature. By sintering diamond particles with Fe, Co, Cu and other metal binders, it has been widely used to prepare various diamond tools for cutting, sawing and drilling. On the other hand, due to the extremely high thermal conductivity of diamond, diamond particles can be used as high-efficiency heat dissipation components for electronic packaging and other fields by forming composite materials with high thermal conductivity metals such as copper, aluminum, and silver. [0003] As a diamond tool, it needs to bear a large cutting force during work, requiring a strong bond between the diamond particles and the metal matrix to prevent the diamond from falling...
