摘要： A bonded abrasive article is provided which includes abrasive grains made of cubic boron nitride within a bond matrix including a silicate. The bonded abrasive further includes a reaction product at the interface between the abrasive grains and bond matrix comprising a transition metal nitride. Further, the invention relates to a manufacturing method comprising providing a glass powder comprising a transition metal oxide compound; combining the glass powder with abrasive grains comprising cubic boron nitride; forming the glass powder and abrasive grains to form a green article; and sintering the green article at a transformation temperature to form abrasive grains in a vitreous bond matrix, the transformation temperature changing the transition metal oxide compound to a transition metal nitride compound at the interface of the abrasive grams and the vitreous bond matrix.

摘要： A vitrified superabrasive product includes a superabrasive component and a vitrified bond component in which the superabrasive component is dispersed. The vitrified bond includes an oxide of a lanthanoid. Additionally, the vitrified bond component defines pores that can be essentially all less than 800 μm in diameter. Seventy percent of the pores are in a range of between about 40 μm and about 500 μm and have an average aspect ratio less than about 2. The porosity is in a range of between about 50% and about 90% of the total volume of the superabrasive product.
