“…Metal-bonded diamond grinding wheels have been introduced to processing of hard materials such as glass, ceramics, sapphire, semiconductor materials or other non-metal materials several decades ago because of their high bond strength, rigidity and good shape retention. These unique properties can improve the surface quality of the workpieces and increase rates of material removal [1,2]. The metal-bonded diamond wheels consist of randomly oriented diamond particles embedded in a metal matrix.…”

In this paper, semi-solid metal (SSM) processing was first applied to fabricate Al-based matrix and diamond composites. A kind of Al-Cu alloy with an adequate solidification range was chosen. Samples of Al-Cu alloys were fabricated by rheocasting with different processing parameters. Specimens of Al-based matrix and diamond composites were fabricated by rheocasting and hot press sintering technology respectively. Microstructures, transverse rupture strength (TRS), hardness and wear resistance were studied. Experimental results revealed that the TRS of the Al-based matrix and diamond composites fabricated by rheocasting increased by 157% and 115% respectively compared to the ones fabricated by hot press sintering technology. The fracture surfaces of the rheocasting specimens exhibited ductile cup and cone behavior as well as strong bonding between the matrix and diamond grits.

In this paper, two metal-bonded diamond wheels with different porosity were fabricated. The porosity of diamond wheel without additives of pore inducers is 7% and the wheel with pore inducers is 38%. Grinding experiments with these two grinding wheels on marbles were carried out under different grinding conditions. Experimental results revealed that highly porous grinding wheel has smaller grinding forces and better self-sharpening ability than the compact grinding wheel under the same grinding conditions.
