Description
Technical field
The utility model belongs to the technical field of synthesis device, is specifically related to the protector of the cubic hinge press used in a kind of cubic boron nitride building-up process.
Background technology
Cubic boron nitride (cBN) is a kind of multifunctional material in machinery, calorifics, optics, chemistry, electronics etc. with the pure Prof. Du Yucang of premium properties, its hardness is only second to diamond, but have excellent thermal conductivity, heat endurance and high high temeperature chemistry inertia and resistance to chemical corrosion, this makes cBN cutter in the processing of solution superhard material, shows huge advantage with in car generation mill reform traditional processing etc.
At present, static state high-temperature high pressure membrane by accelerant process is the most popular method of synthesis cBN monocrystalline, with the nitride of hexagonal boron nitride (hBN) powder and Li, Mg, Ca etc. or boron nitride catalytic powder for raw material, briquet after Homogeneous phase mixing, is then positioned in cubic hinge press and is carried out HP-HT synthesize to obtain cBN crystal.Compared with elemental metals, adopt their nitride, boride does catalyst, can reduce synthesis condition, the crystal quality obtained is high, and impurity content is few, is current most widely used catalyst material.
But relative to diamond transition mechanisms, cubic boron nitride relates to the conversion of B, N two kinds of elements, more complicated than the diamond be only made up of C element is many, adds the limitation of characterization method, makes the transformation mechanism progress of cBN slow.Because under high-temperature and high-pressure conditions, on-line checkingi has difficulties, therefore, generally adopt the mode of rapid cooling to retaining all multi information under high-temperature and high-pressure conditions to Synthetic block, especially the research of monocrystalline interface information to cBN growth mechanism has great importance.Wherein a kind of method is with Li
3n is catalyst raw material, be that raw material synthesizes cBN large single crystal particle at high temperature under high pressure with hBN, then " quenching " fast cold treatment is carried out to the sample after synthesis, with retain a large amount of with cBN in the information, the particularly composition information at cBN monocrystalline interface that high temperature downgrowth is relevant.By to the observation of pattern around cBN monocrystalline and the analysis of thing phase, the desk study growth course of cubic boron nitride.Be carry out on domestic DS-029B type hinge type cubic hinge press in experimentation, pressure calibration is with reference to the high pressure phase height of bismuth, thallium and barium, and temperature platinum rhodium thermocouple is demarcated.Purity is selected to be greater than the Li of 99.5%
3n does catalyst raw material, makes initial feed, mix rear briquet carry out HP-HT synthesize in the ratio of 1:9 with the hBN that purity is 99%.Synthesis pressure used in experiment is 4.5GPa, temperature 1600 DEG C, temperature retention time 10min.Synthetic block fracture apperance adopts JSM-6380LA type SEM to observe, and judges the granular size of cubic boron nitride, shape and distribution situation, thus judge the synthesis quality of cubic boron nitride with this.Carry out the sample preparation of high-resolution transmission test by means of light microscope, utilize JEOL-2010F type high resolution transmission electron microscopy to carry out material phase analysis.
As can be seen from above cubic boron nitride building-up process, a kind of equipment used is needed to be cubic hinge press, cubic hinge press is in use due to the reason of certain complexity, there will be the phenomenon that one is referred to as " blowing out ", namely top hammer can explode into fine grained chippings, then fly out from the space of cubic hinge press, because fine grained chippings has very large lethality, therefore one piece of baffle plate can be set in the gap of existing cubic hinge press, play the effect of stop, because the baffle plate of press gap is not easily fixed, therefore the blocking effect of baffle plate is not satisfactory, easy appearance is dangerous, and baffle plate on high pressure apparatus also unsightly.
