Abstract

Abstract

The diamond powder manufacturing industry at present grapples with a large backlog of fine-grained diamond powders. To enhance its applicability, agglomerated abrasive samples were manufactured with aluminum-borosilicate binder as the bonding agent, Si powder and Ti powder as additives. These agglomerated abrasive samples were then added into an aluminum-borosilicate binder to create ceramic bond samples. The bending strength, phase composition, and microscopic morphology of the samples were analyzed. The results show that the Al-B-Si binder, when combined with Si or Ti, can agglomerate diamond. When the mass fraction of Si or Ti in the agglomerated abrasives is 10.0%, the bending strength of the ceramic bond samples prepared is the largest. The bending strength of the agglomerated abrasive sample with Si added is 43.74 MPa. When the mass fraction of Si or Ti exceeds 10.0%, a large number of Si or TiO₂ peaks appear in the agglomerated abrasive samples, and its bending strength decreases sharply. Compared with the agglomerated abrasive sample added with Ti, the agglomerated abrasive sample added with Si has a larger particle size and a more uniform particle size distribution. 1～2 μm abrasives can be aggregated into 5～10 μm abrasives with the addition of Al-B-Si binder with Si.
