Present invention additionally comprises a kind of preparation technology of guide wheel, step are as follows：
S1, after the FeB ores of broken mistake are crossed into 50 mesh sieves, and carbon dust is together, adds acetone and puts ball milling 36 hours in ball grinder into,
Then other 10 hours of metal dust batch mixing are added, batch mixing uniformly adds binder paraffin and dispersant OP-10 third afterwards
It is dispersed with stirring out in ketone, then ball milling 4-6 hours；
S2, the slurry after ball milling first sieves to be separated with ball, then static ten hours, makes pulp separation into two layers, metal
Powder etc. is sink to bottom, and upper strata is clear liquid, is then first filtered, re-dry, should be under vacuum condition when drying, vacuum 8.0*
10-2Pa, in order to allow ball milling solvent acetone to volatilize completely, 8 hours should be incubated at 80 DEG C, should not be constantly in holding stage
Vacuumize, the condition of high vacuum degree in holding furnace, to wait powder completely to cool down after insulation could take out；
S3, unidirectionally suppressed with mould, in pressing process, the unrestrained slow 120-150Mpa that are forced into of J are compressing, and the mm of pressurize 1, often
The sample that size is 70mmX 11mmX9mm is made in 30g powder；
S4, using vacuum sintering furnace sintering furnace, vacuum is up to 10- 2,In high temperature, temperature deviation is within 5 DEG C；Liquid phase exists
1113 DEG C start to produce, and after liquid phase produces, Mo2FeB2 particles are close to being suspended in liquid phase；
Lost-wax casting is also named in S5, precision-investment casting, is that fusible material such as paraffin etc. is made into meltability mould, then again molten
Several layers of special refractory material is coated on mould, then by drying and chemicosolidifying forms the module of an entirety, then from mould
Fusible pattern is melted in group, obtains a hollow shell, then shell is put into roaster through high-temperature roasting, wherein finally
Molten steel is poured into, obtains a smooth casting in accurate size, surface；Before molten steel is poured into, Mo2FeB2Based ceramic metal ring will
A part as shell, which is put into stove, to be calcined, and will not be drastically heated and crack because of molten steel is poured into suddenly.
Raw material includes Mo, FeB, C, Ni, Cr and Fe in step S1, and mass percent is followed successively by：43.1%、31.1%、0.8%、
2%th, 10% remaining be Fe；
Sintering process parameter is：Low pressure carrier gas is passed through in 380 DEG C of dewaxing stages, is chosen in the selection of L1 liquid phase sintering conditions
1140 DEG C are used as liquid phase L1 to form temperature, and final sintering temperature elects 1260 DEG C as, and is incubated 30min at this temperature；
More preferable dewaxing effect can be reached by being passed through a small amount of hydrogen dewaxing, and the holding temperature of liquid phase is that 1140 DEG C of soaking times are 30
Minute sintering process can prepare that hard-phase particles are tiny and equally distributed sample, the more a height of HRA88 of hardness, bending resistance are strong
Spend highest 1540Mpa；
During using high-speed steel as friction pair, Mo2FeB2The wearability of based ceramic metal is better than W, Co series hard alloys and high-speed steel.
Use Mo2FeB2Base clad material, which prepares Compound guide wheel, turns into a kind of possible.
Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of changes, modification can be carried out to these embodiments, replace without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
