Title:
ダイヤモンド含有研磨用製品の製法
Document Type and Number:
Japanese Patent JP2004505786
Kind Code:
A
Abstract:
A method of producing an abrasive product comprises providing a mixture of a mass of discrete carbide particles and a mass of diamond particles, the diamond particles being present in the mixture in an amount such that the diamond content of the abrasive product is 25% or less by weight, and subjecting the mixture to elevated temperature and pressure conditions at which the diamond is crystallographically stable and at which substantially no graphite is formed, in the presence of a bonding metal or alloy capable of bonding the mixture into a coherent, sintered product, to produce the abrasive product. The bonding metal or alloy is preferably a combination of a transition metal or a transition metal alloy and up to 40% by volume of the bonding metal or alloy of a second metal which is a stronger carbide former than the transition metal or the transition metal alloy, or an alloy of the second metal.
