The technical scheme of the invention is that the brazing diamond comprises a substrate, wherein the substrate is provided with a nickel-based brazing filler metal, and the nickel-based brazing filler metal is provided with diamond.
A method for preparing brazing diamond comprises the following steps:
step S: processing a cast iron blank to form a matrix;
step S: bonding the nickel-based brazing and the diamond on a substrate according to a certain proportion;
step S: and putting the bonded finished product into a vacuum furnace.
In the step S, welding may be performed one or more times.
The brazing diamond and the preparation method thereof, which are manufactured by the technical scheme of the invention, improve the thickness of the nickel-based brazing diamond, realize multilayer brazing of the nickel-based brazing diamond, improve and increase the performance of a tool of the nickel-based brazing diamond, reduce the thermal expansion coefficient of the matrix by changing the performance of the matrix of the nickel-based brazing diamond, change the shrinkage stress during welding, and realize a thicker brazing layer.
