Specific embodiment
To facilitate the understanding of the present invention, below with reference to several embodiments, still, the present invention can be with many different shapes
Formula is realized, however it is not limited to embodiment described herein, on the contrary, purpose of providing these embodiments is makes to of the invention
Disclosure is more thorough and comprehensive.
It should be noted that it can directly on the other element when element is referred to as " being fixedly arranged on " another element
Or there may also be elements placed in the middle；When an element is considered as " connection " another element, it, which can be, is directly connected to
To another element or it may be simultaneously present centering elements；Term as used herein " vertical ", " horizontal ", " left side ",
" right side " and similar statement are for illustrative purposes only.
Unless otherwise defined, all technical and scientific terms used herein and belong to technical field of the invention
The normally understood meaning of technical staff is identical；Term as used herein in the specification of the present invention is intended merely to description tool
The purpose of the embodiment of body, it is not intended that in the limitation present invention；Term " and or " used herein includes one or more phases
Any and all combinations of the listed item of pass.
The basic composition material accounting of a kind of preparation method of rare earth silicon carbide abrasive, rare earth silicon carbide abrasive is respectively:
Be carbonized silicon 60%~75%, aluminium oxide 1%~2%, lanthana 2%~3%, coal tar 5%~8%, ceramic fibre 4%~7%
And schmigel 10%~16%, the basic material of this abrasive material constitute in be added to small amounts aluminium and rare earth element lanthana,
The hardness and toughness of abrasive material are improved, while the addition of a little ceramic fibre improves the wear-resisting property and heating conduction of abrasive material,
If not adding lanthana, lack rare earth element, higher, while the distinctive resistance to height of rare earth element is not achieved in the hardness of entire abrasive material
Warm nature can make the high temperature resistance of entire abrasive material higher than the high temperature resistance of traditional silicon carbide abrasive.
Above-mentioned aluminium oxide and lanthana is nanometer grade powder, if not using nanometer grade powder, when being mixed,
Gap between powder particle is big, can not preferably merge between each material, and uses nanometer grade powder, nanometer grade powder
Between the smaller density for improving abrasive material in gap increase intensity, surface is more smooth.
Above-mentioned preparation method is mixed, is heated for will be carbonized silicon, aluminium oxide, lanthana, coal tar and schmigel
To mixture, abrasive material further is prepared to mixture.
