Abstract
The application provides a method for preparing a high-strength and high-toughness twin diamond ring by regulating plasma, and relates to the technical field of chemical vapor deposition. The method comprises the following steps: step S1, preparing a circular ring-shaped substrate; step S2, performing primary deposition by using a rotating pulse method to obtain a primary-processed twin diamond ring; step S3, performing secondary deposition by using the rotating pulse method to obtain a re-processed twin diamond ring; and step S4, surface treatment of the twin diamond ring. The application regulates the size of the relative rotation speed of the plasma source by using the rotating pulse method to generate pulse-type energy fluctuation. The method has the advantages of simple device operation and low preparation difficulty, and the obtained twin diamond ring has high strength and high toughness and can be used in the actual production of pure diamond grinding wheels.
