美国Charles River Associates公司最近在一篇题为“对新型陶瓷材料的技术性能和经济性能的评定”的报告中总结说:新型陶瓷(即性能改进的陶瓷)材料使切速增加,与传统的硬质合金刀具相比,陶瓷刀具不仅耐磨,且寿命也较高。在目前所使用的陶瓷刀具中,铝基陶瓷占95%。断裂韧性不足是铝基陶瓷一直不能得以广泛应用的主要障碍,但使用不正确和操作不当乃是其中的关键因素。
In a recent report entitled “Evaluation of the technical and economic performance of new ceramic materials,” Charles River Associates of the United States concluded that the new ceramic (ie, performance-enhancing ceramic) material increases the speed of the cut, Compared to quality alloy tools, ceramic tools not only wear-resistant, and life is also higher. In the current use of ceramic cutting tools, aluminum-based ceramics accounted for 95%. Insufficient fracture toughness is a major obstacle to the widespread use of Al-based ceramics. However, incorrect use and improper operation are the key factors.
