Description
Technical Field
The invention relates to the technical field of diamond surface pretreatment, in particular to a method for metallizing a pre-brazed diamond surface.
Background
The diamond belongs to a non-metallic material, and the interface energy between the diamond and metal or alloy is very high, so that most of simple substances of metal or alloy are difficult to effectively wet the diamond, and the diamond is difficult to fall off prematurely due to insufficient holding force of a metal or alloy matrix on the diamond in the use process of pressing a bonding agent diamond tool such as a diamond saw blade and a drill bit by metal powder, the utilization rate of the diamond is very low, and the diamond tool only exerts about 20% of the working efficiency actually reported, thereby seriously influencing the service life of the diamond tool.
In order to improve the holding force of the matrix to the diamond, the surface of the diamond is usually coated, for example, Ni and Cu are plated by chemical plating and electroplating, Ti, Cr, W and the like are plated by vacuum micro-evaporation, and after Ti is plated, Ni is electroplated to form a Ti — Ni composite plating layer. However, these treatments all have some drawbacks: the surface plated with Ni, Cu and the like can only form mechanical combination with the surface of the diamond, and gaps exist between the plating layer and the diamond, so that the improvement on the holding effect of the diamond is limited; in the vacuum micro-evaporation method, although a TiC layer is generated on the interface between a Ti-plated layer and diamond, the chemical bond is formed by the bonding between the plating layer and the diamond, the Ti-plated layer is very thin, and no clear explanation is found on how the formed TiC/Ti layer is bonded with the interface of a matrix bonding agent; the Ti-Ni composite plating layer is generated by TiC and TiNi compounds, but the nickel layer with high melting point also has the problem of interface bonding with a carcass binder, and is not suitable for all carcass binders, particularly in a carcass with low nickel content or even without nickel.
Cu, Sn and their alloys are common binder elements in diamond metal bond tools, and the invention patent application with patent application number 201610862345.7 discloses a diamond surface metallization method: the method comprises the steps of uniformly mixing cleaned diamond with molten salt such as NaCl, micro-nano metal Cu and micro-nano active material metal Cr according to a certain proportion, and preserving heat for 0.5-3 hours at 800-1000 ℃ in a non-oxidizing atmosphere to obtain the diamond particles coated with the gradient surface modification consisting of a reaction carbide layer, an active material layer and a metal Cu layer. The method is complex in process, proper isolating agents are needed between the diamonds to prevent the diamonds from being adhered together, the surfaces of the diamonds are corroded seriously, and the coating is discontinuous.

In step 3, the non-oxidizing atmosphere is a vacuum atmosphere, an inert atmosphere or a hydrogen reducing atmosphere.
In the step 3, the heat treatment temperature is 600-850 ℃, and the heat treatment time is 20-60 min.
