A structurally stable diamond wire and its preparation method

Abstract

The invention discloses a structurally stable diamond wire and a preparation method thereof, comprising an inner core, an inner coating, a connecting layer, an outer coating, and diamond particles; the connecting layer of the invention is composed of asbestos fibers, nano-alumina, and epoxy resin; The outer end of the diamond particles extends to the outside of the outer coating, and the inner end of the diamond particles is embedded and extends to the inside of the connection layer, so that the inner end of the diamond particles is directly embedded in the connection layer with a large internal surface area and a dense interlaced structure, which greatly increases the diamond density. The stability of the particle connection structure; the connection structure of the structurally stable diamond wire of the present invention is stable, and the preparation method is unique.

Description

technical field [0001] The invention relates to a structurally stable diamond wire and a method for preparing the same. Background technique [0002] Electroplated diamond cutting wire is a cutting tool made by consolidating diamond particles onto metal wires by electroplating. It is mainly used for cutting hard and brittle materials such as silicon crystals, sapphires, and ceramics. The existing diamond wire is generally obtained by electroplating the outer coating and diamond particles on the outside of the steel wire, but the diamond particle structure of such a diamond wire is not stable, so it is necessary to develop a diamond wire with a stable abrasive particle connection structure and its preparation method . Contents of the invention [0003] Aiming at the shortcomings of the above-mentioned prior art, the problem to be solved by the present invention is: to provide a diamond wire with a stable abrasive particle connection structure and a preparation method there...
