绪言今天,陶瓷在现代工业技术中担负着一个重要角色。近十年来,陶瓷刀具在提高机械加工生产率方面所起的作用,日益引人注目。正因为这一点,氧化物陶瓷切削刀具的销售量增加了,1976年销售额约300万美元,1981年增加到1500万美元左右。有吸引力的新的陶瓷材料及其应用是符合现代化要求的。有些不熟悉今天的现代陶瓷切削刀具的人,认为老式陶瓷工具
Introduction Today, ceramics play an important role in modern industrial technology. In the past decade, the role of ceramic tools in improving machining productivity has drawn increasing attention. Because of this, sales of oxide ceramic cutting tools have increased, with sales of about 3 million U.S. dollars in 1976 and about 15 million U.S. dollars in 1981. Attractive new ceramic materials and their applications are in line with modern requirements. Some people who are not familiar with today’s modern ceramic cutting tools think of vintage ceramic tools
