据英国《材料前沿》杂志1991年9月号报道,一种新型的全陶瓷涡轮转子已成功地在日本经受了高温强度试验。由三菱汽车公司、三菱重工业公司和NGK绝缘子公司共同研制的这种全陶瓷转子可以在新一代汽车燃气涡轮机计划的工作条件下运转。 氮化硅工艺的最新进展已能使这种全陶瓷转子承受1400℃以上的涡轮进气口温度,而以前的转子的温度极限是1300℃,而且机(?)强度也增加了。因此,转子能以更高的速度运行更长的时间。
According to the September 1991 issue of the “Materials Frontier” magazine in the United Kingdom, a new all-ceramic turbine rotor has been successfully subjected to high temperature strength tests in Japan. The all-ceramic rotor, developed jointly by Mitsubishi Motors Corporation, Mitsubishi Heavy Industries and NGK Insulators, operates under the planned operating conditions of a new generation of automotive gas turbines. Recent developments in the silicon nitride process have enabled the all-ceramic rotor to withstand turbo inlet temperatures above 1400 ° C, compared to the previous rotor temperature limit of 1300 ° C and increased machine (?) Strength. Therefore, the rotor can run at a higher speed for a longer period of time.
