Abstract

The invention discloses a preparation method of a low-temperature co-fired ceramic super-hard abrasive polymer based on 3D printing, and belongs to the field of additive manufacturing and super-hard material preparation. The method comprises following steps: preparing a 3D printed low-temperature co-fired ceramic bonding agent; step 2, mixing the low-temperature co-fired ceramic bonding agent, a super-hard abrasive and an adhesive, and molding the mixture in 3D printing equipment to obtain a to-be-fired polymer; and step 3, placing the obtained polymer to be sintered in an environment of 700-1000 DEG C at a heating rate of 2-20 DEG C / min, and maintaining the temperature for 0.5-3 hours to prepare the low-temperature co-fired ceramic super-hard abrasive polymer based on 3D printing. The low-temperature co-fired ceramic bonding agent can be reliably connected with a super-hard abrasive, the bonding strength is improved, the microcrystalline glass is formed through high-temperature smelting, and the microcrystalline glass in the low-temperature co-fired ceramic can permeate into gaps between ceramic particles and super-hard abrasive particles in the sintering process, so that the compactness of the prepared polymer is improved.

Description

technical field

[0001] The invention relates to a method for preparing a low-temperature co-fired ceramic superhard abrasive polymer based on 3D printing, and belongs to the fields of additive manufacturing and superhard material preparation. Background technique

[0002] In aerospace, national defense and high-end equipment manufacturing fields, due to their special industry attributes, the materials involved often need to meet the requirements of high hardness, high wear resistance and reliable connection strength. Diamond is extremely hard and thus has excellent wear resistance. Compared with diamond, cubic boron nitride (CBN) is a new type of artificially synthesized superhard material, which has a lower affinity with ferrous metals, so it has a wider range of processing applications than diamond. Diamond and CBN are the most widely used known superhard materials.

[0003] Ceramic materials have the characteristics of high hardness, wear resistance, and good chemical i...
