Preparation method of novel aluminum-magnesium-boron-titanium superhard grinding material
The invention discloses a preparation method of a novel aluminum-magnesium-boron-titanium superhard grinding material, which comprises the following steps: 1. thoroughly mixing Al, Mg and B powder, filling in a crucible, sintering, crushing and screening to obtain aluminum-magnesium-boron powder; 2. mixing the aluminum-magnesium-boron powder and hardness reinforcing powder, and granulating to obtain aluminum-magnesium-boron-titanium granules; 3. mixing the aluminum-magnesium-boron-titanium granules obtained in the step 2 with carbon powder, filling in a graphite mold, and sintering to obtain a block material of aluminum-magnesium-boron-titanium granules; and 4. removing the carbon powder from the block material of aluminum-magnesium-boron-titanium granules subjected to hot pressed sintering, crushing, screening, and grading to obtain the aluminum-magnesium-boron-titanium superhard grinding material. The preparation method has the advantages of flexible synthesis conditions, low synthesis temperature, low energy consumption, high cleanness, environmental protection, low production cost and the like, and is suitable for mass production. The aluminum-magnesium-boron-titanium superhard grinding material prepared by the method has the advantages of high hardness, low density, low friction factor, favorable self-lubricating property, high temperature oxidation resistance and other excellent comprehensive properties.
