Abstract: In order to improve the machining performance of the new type porous metal bond wheel, a new attempt were carried out for fabricating porous metal bond matrix with adjustable and high porosity as well as large pore size by use of pore-forming agent ammonium bicarbonate (NH4HCO3) and a vacuum loose powder sintering process. The porosity, bending strength and microstructure of the as-sintered porous metal bond matrix have been studied. The results show that the pore-forming agent NH4HCO3 with a certain amount ca… Show more
