Abstract
【解決手段】研磨材料が、基材10を接着剤11で被覆し、その基材に硬質粒子12を接触させ、その後接着剤で保持されない全ての粒子を除去する。残留する粒子は、粒子が一時的に保持されている間に焼結可能ないし融合可能な材料で囲まれる。基材は、所望のパターンを得るために粒子が或る領域に固着するように或るパターンで付与され、あるいは均一にカバーされ、かつマスクされるような接着剤を有している。粒子が基材上に保持されている間、粒子を配向するために物理的力が均一に付与され、次いで、粉末が付与されるか、あるいは基材がプリフォームに付与される。熱および/または圧力の引続く処理で研磨材料を完成する。
【選択図】図1
Description
そして、硬質粒子が基材上に置かれて固着した後、マトリックス材が硬質粒子および/または基材に適用される。このように、マトリックス材は複合研磨材料となり各粒子は所望のパターンでマトリックス材によって保持されることを特徴とするものである。
