据国外综合报导,七十年代初,为发展耐高温的涡轮发动机材料,曾研制了一组新的陶瓷Sialon(是Silicon-Aluminium-Oxygen-Nitrogen的缩写)。由于这种材料具有良好的机械性能和耐高温性能,因此多年来,英、日、美等国都在研究用这种材料作切削刀具。最近,英国Lucas工业公司已成功地改进了Sialon材料的机械和耐热性能。据称,这种含有少量的
According to a comprehensive report from abroad, a new set of ceramic Sialon (an abbreviation of Silicon-Aluminum-Oxygen-Nitrogen) has been developed for the development of high-temperature turbine engine materials in the early seventies. Because of this material has good mechanical properties and high temperature performance, so for many years, Britain, Japan, the United States and other countries are studying the use of such materials as a cutting tool. Recently, Lucas Industries UK has successfully improved the mechanical and heat resistance properties of Sialon materials. Allegedly, this contains a small amount
