Abstract
The utility model relates to a Ti-Ni composite structure of a silicon polycrystal diamond. A Ti coat is arranged on the silicon polycrystal diamond (SiPCD); a coat of Ni is arranged on the Ti coat. The utility model has the advantages that diamond is bonded to the interface of the SiPCD and the composite plating through strong metallic bond, thereby improving the bonding strength and hold of the SiPCD to the binding agent; the higher heat durability is available, thereby isolating and protecting the SiPCD so that the SiPCD is uneasy to be oxidated and graphitized or generate carbide when subjected to high sintering and high-temperature grinding. The SiPCD with Ti-Ni composite plating is predominantly used to trim pens, drill bits for geology and petroleum, and wear-resistant parts, providing high bonding strength between the SiPCD and the grinding tool body, thus improving the cutting sharpening level, machining efficiency and period of usage of the grinding tool.
Description
Technical field
The utility model relates to a kind of diamond silicon glomerocryst (Si PCD) titanium nickel composite construction.Belong to the tool materials technical field.
Background technology
Diamond silicon glomerocryst (Si PCD) material is very extensive in industrial application, can make multiple instrument as finishing pen, geology drill bit, oil bit, wearing piece etc., because the characteristic of diamond silicon glomerocryst (SiPCD) material itself, combine very difficult with other material, so the matrix from instrument comes off easily, cause the service life of instrument low, production cost increases.
The utility model content
The purpose of this utility model is to improve existing diamond silicon glomerocryst (Si PCD) and combines the shortcoming of difficulty and a kind of diamond silicon glomerocryst (Si PCD) titanium nickel composite construction is provided with other material.
For achieving the above object, the utility model is taked following design: diamond surface has a titanium layer; One nickel dam is arranged on described titanium layer.
The utility model advantage mainly is: this diamond silicon glomerocryst (Si PCD) has the titanium layer of powerful metallic bond combination on described interface, can improve the bond strength and the hold of diamond silicon glomerocryst (Si PCD) and bond; Improve the intensity of diamond silicon glomerocryst (Si PCD); Give diamond silicon glomerocryst (Si PCD) surface higher hear resistance, (Si PCD) plays the insulation blocking effect to diamond silicon glomerocryst, makes it avoid taking place oxidation, graphitization, solvation or generation carbide when high temperature sintering and high temperature grinding.Diamond silicon glomerocryst (Si PCD) with Ti-Ni composite deposite is mainly used in finishing pen, geology drill bit, oil bit, wearing piece etc.Use it can make diamond silicon glomerocryst (Si PCD) and tool base that higher binding strength is arranged, and improve the wearability and the sharpness of grinding tool, improve working (machining) efficiency, prolong the service life of grinding tool.
Description of drawings
Fig. 1 diamond silicon of the present utility model glomerocryst (Si PCD) part section structural representation.
The specific embodiment
Embodiment 1: as shown in Figure 1, there is a titanium (Ti) layer 2 on diamond silicon glomerocryst of the present utility model (Si PCD) 1 surface; One nickel (Ni) layer 3 is arranged on described titanium (Ti) layer 2.
Embodiment 2: diamond silicon glomerocryst (Si PCD) 1 is graininess, sheet, cylindric, strip, polygon or the like a multiple shape, it has the scraggly pattern surface of microcosmic, described titanium (Ti) layer 2, nickel (Ni) layer 3 form composite bed, parcel diamond silicon glomerocryst (Si PCD) 1.
Claims (2)
1, a kind of diamond silicon glomerocryst titanium nickel composite construction, it is characterized in that: there is a titanium Ti layer on the top layer of diamond silicon glomerocryst, and there is a nickel layer outside of titanium Ti layer.
2, a kind of diamond silicon glomerocryst titanium nickel composite construction according to claim 1, it is characterized in that: diamond silicon glomerocryst Si PCD is graininess or sheet or cylindric or strip or polygonal shape.
