Description
Technical field
Diamond surface preconditioning technique of the present invention field, and in particular to be at diamond surface functional metal
Reason.
Background technique
It is sawed, in gang saw in hot pressing metal-bonded diamond cutting tools such as diamond saw blade, drill bit, rope, frequently with height
Quality coarse diamond, adhering state, carcass bonding agent and Buddha's warrior attendant of the quality, diamond of diamond in carcass bonding agent
Stone synchronizes the key factor that the problem of abrasion is decision diamond tool efficiency and service life.
Normally, it is the adhesive property for improving diamond and carcass bonding agent, diamond is surface-treated, such as to gold
Hard rock surface is roughened, ripple is handled, however, diamond surface roughening and ripple processing can only improve carcass bonding agent to gold
The mechanical of hard rock is held, limited to the raising of diamond tool performance；More work are handled diamond surface metallization,
Ni, Cu are such as plated in diamond surface using chemical plating, plating, the methods of the micro- evaporation of vacuum, molten-salt growth method plate Ti, Cr, W etc. can be with
Diamond formation chemical bonds element or coated various metal powders, and formation composition metal such as Ti-Ni, Ti-Ni-Cu,
Ti-Ni-Ag etc., it is therefore intended that improve carcass bonding agent to diamond it is mechanical hold or by with diamond surface formationization
Key is established between diamond and carcass bonding agent is preferably bonded binder course and to diamond insulation blocking, imparting gold
Hard rock high heat resistance and thermal conductivity make it be not susceptible to oxidation, graphitization when high temperature sintering and high temperature are ground.
However, be all to consider diamond and the segmentation of carcass bonding agent in numerous diamond surface metallization work,
In fact, diamond surface pre-metallization is not final purpose, it is more mainly expectation and carcass bonding agent realization chemical metallurgy
In conjunction with and reach one of the measure of abrasion synchronous with carcass bonding agent.But the it is observed that metallurgical bonding layer being actually formed
Very thin, after sintering saw (brill) tooth into, the diamond exposed on plane of rupture loses coating mostly, in the diamond that fallen off
Residual hole surface also smoother, this phenomenon seems to illustrate that diamond and carcass fail to reach effective chemical coating
It is horizontal, it is also not possible to the firm connection between diamond and carcass to be obtained, in consideration of it, the present invention is proposed by diamond surface packet
Cover composition metal, the chemical bonds of strengthening surface metalization layer and diamond, simultaneous selection is compatible with carcass bonding agent performance
Thickening articulamentum, formed and be plated with the functionalization diamond of complex metal layer, be applied in diamond tool, tying it by force
In mixture carcass, side metallization and carcass bonding agent become a holding being integrally formed to diamond, and in weak binding
In agent carcass, principle is integrally weakened according to local strengthening, diamond forms local strengthening by surface recombination metal layer, thus very
Reach the abrasion synchronous with diamond of carcass bonding agent well, improves service efficiency and the service life of tool.
Summary of the invention
It is an object of that present invention to provide a kind of surface metalation functionalization diamonds, can be applied to eurytopicity strong/weak
In bonding agent carcass, in the chemical bonds of strengthening surface metalization layer and diamond, metallic bond is improved to diamond handle
While holding, side metallization and carcass bonding agent in strong bonding agent carcass is made to become an entirety, and in weak binding agent
It in carcass, forms local strengthening and integrally weakens, reach the abrasion synchronous with diamond of carcass bonding agent, improve the use effect of tool
Rate and service life.
To reach above-mentioned purpose, the technical scheme adopted by the invention is that:
A kind of functionalization diamond of coating surface complex metal layer, comprising the following steps:
Step 1, elder generation are in one layer of titanium layer of diamond surface plating；
Step 2, then one layer of reinforcement bonded layer of plating again on plating titanium layer；
Step 3, one layer of thickening articulamentum of plating again on reinforcing bonded layer.
In step 1, the titanium layer uses the micro- evaporation plating of vacuum, and the weight gain of titanium layer is the 0.1 of the diamond weight
~1wt%, titanium layer and diamond surface form TiC chemical bonds.
In step 2, the reinforcement bonded layer be using chemical coating, metal lining may is that Ni-Cr-P, Ni-W-P,
Co-W-P, Ni-Mo-P, one of Ni-M-Re-P；M, which can be Cr/W/Mo/V, Re, in Ni-M-Re-P can be rare earth element
Ce/Y/La/Pr/Nd。
In step 3, the thickening articulamentum be using galvanoplastic plating, metal lining may is that Ni, Ni-Fe, Ni-Co,
One of Ni-Co-Mn, Ni-SiC, Ni-P, Ni-B, Ni-P-SiC, Ni-B-SiC.
The thickening articulamentum, it is characterised in that: preferably, coating shows partially hard crisp characteristic, in order to diamond
The sword out when tool uses.
The thickening articulamentum, it is characterised in that: the thickening articulamentum metal lining is according to carcass bonding agent situation
Selection, the thickness of the also thickening layer of simultaneous selection.
The thickening articulamentum, it is characterised in that: thicken the thickness of articulamentum and measured with coating weight gain, increase weight range
10~100%, weight gain calculation formula is to plate thick gross weight to subtract diamond original weight the difference between the two divided by resulting after the thick gross weight of plating
Percentage.
Since the coating such as common plating Ti, Cr, W are very thin, it is a company that MeC generated is reacted with diamond interface not
Subsequent layers are only dispersed in the certain positions for being easy to raw core of diamond surface and form island connection, therefore it shows to diamond
There are apparent limitations with the raising of carcass bonding agent binding performance, this also be reflected in adaptability and combination to carcass bonding agent
In intensity.The present invention one layer of reinforcement bonded layer of plating again on the basis of titanizing, further enhances metalization layer to diamond
Holding, one layer of the plating thickening articulamentum compatible with carcass again on reinforcing bonded layer, thus in reinforcement metalization layer to gold
While hard rock is held, side metallization and carcass bonding agent are formed into an entirety.
Present invention process is simple, easy to implement, strong applicability.
