Description
Technical field
The present invention relates to superhard honing technique field, refers in particular to a kind of preparation method of hybrid superhard honing stone.Especially
It is a kind of preparation method for plating the superhard honing stone of tungsten abrasive particle, its object is to strengthen the interface between abrasive particle and metal binding agent
With reference to optimization preparation technology with improve the grinding efficiency of honing stone, self-sharpening, service life and reduce production cost.
Background technology
Superhard honing is a kind of hone (such as honing lever, disk, wheel, disk) using diamond or/and CBN for abrasive particle
Finishing and finishing are carried out to surfaces such as metal, ceramics, glass, hard alloy workpiece endoporus, periphery, plane, special surfaces
Processing method.Superhard hone is widely used in engineering and mining machinery, derived energy chemical, electronic apparatus, Aero-Space, vehicle
The industries such as ship, high performance superhard hone has high efficiency, high accuracy, the long-life, self-sharpening is strong, do not block, need not
The advantages that finishing.The development of superhard hone is related to Material formula makeup (such as metallic bond formula, abrasive grain content, composition
And grain size distribution etc.), shaping, sintering and the welding procedure of honing knife cover and metalwork, the design of the external structure of hone
Etc. all many-sides.
Existing superhard honing stone, can fail in the case of working long hours, and be its bonding agent the reason for failure
In diamond or CBN lose ablation, and have two kinds the reason for cause such case：(1) diamond or CBN and metal knot
Adhesion between mixture is inadequate so that Grain Falling Off in grinding process；(2) self-sharpening of metallic bond is inadequate, top layer mill
After abscission, the abrasive particle of bottom can not quickly be exposed, and oilstone loses grinding performance.For the two reasons, a side
Face needs to carry out abrasive particle metallization pretreatment, while also to select suitable honing stone metallic matrix.
According to data-searching, the surface metalation on diamond is modified, in order to improve the boundary of diamond and metal material
Face binding ability, some scientific workers are to diamond surface plating layer of metal, such as Chinese patent ZL201110160262.0
" a kind of honing abrasive belt " carries out plating Ni pretreatments to diamond abrasive grain；A kind of Chinese patent ZL201310322141.0 " diamonds
The method that tungsten is plated on surface " and document " salt baths of Tang little Wen, Liu Qing friend's diamonds plates tungsten, Southwest Petroleum Institute journal, and 1998,20
(4):63-65. " uses tungsten powder to plate tungsten to diamond surface in vacuum drying oven or resistance furnace using salt bath process for tungsten source, with this Shen
It please compare, because the cleanliness factor of tungsten atom in course of reaction is poor so that it is plated, and tungsten pretreatment process is more complicated, and tungsten source cost is also more
Height, and be not sintered with plating tungsten CBN abrasive particles with metallic bond further and prepare superhard honing stone；Such as Chinese patent

Much like with diamond according to data-searching, CBN properties are stable, also poor with the interfacial combined function of metal material.
Surface metalation on CBN abrasive particles is modified, and is used using magnetron sputtering apparatus evaporation plating Ti, Mo, W, Cr and conjunction
Gold etc., such as document, " Wang Yanhui, Wang Mingzhi, institute make the country prosperous, diamond, the CBN abrasive materials of micro- evaporation plating Ti, Mo, W, the Cr of vacuum and alloy
And product properties detection, diamond and grinding materials and grinding tool engineering, 1995,5 (89)：21-24 ", also have and work is synthesized using HTHP
Skill realizes cubic boron nitride particle surface titanium-nitride, such as a kind of Chinese patent ZL201310536406.7 (cubic boron nitrides
The method of grain surface titanium-nitride), or using plating or Electroless Plating Ni.
According to data-searching, on hybrid superhard honing stone, existing hybrid superhard honing stone almost all
Directly using diamond and CBN abrasive particles and metallic bond powder mixing hot pressed sintering without pre-metallization processing, such as China
Patent 201410666702.3 " a kind of hybrid super hard abrasive honing stone ", a kind of " top gem of a girdle-pendant of Chinese patent 201110445617.0

Above with respect to the preparation method of hone, it presently, there are plating Ti or plating Ni diamonds or CBN abrasive particles be applied to the top gem of a girdle-pendant
Grind oilstone, and it is rarely seen will plating tungsten diamond or CBN abrasive particles be applied to honing stone, more have no plating tungsten diamond and CBN abrasive particles use
To prepare hybrid superhard honing stone.In fact, diamond or CBN abrasive particles plating tungsten is compared with plating Ti or plating Ni, due to Ti and
Plate Ni activity it is bigger than W, in sintering process, they easily enter the metallic matrix of honing stone, such as with metallic bond
The metal such as Cu, Sn form weld metal zone brittle intermetallic thing, the graphitization of diamond can also be caused by plating Ni in addition, so as to influence honing
Oilstone honing performance.
The content of the invention
