Zirconia Ceramics:
Zirconia is a new important structural material used in the aerospace industry. Its specific gravity, strength and service temperature are between aluminum and steel, but it is stronger than aluminum and steel and has excellent seawater corrosion resistance and ultra-low temperature performance. In 1950, the United States used it for the first time on F-84 fighter-bombers as non-load-bearing components such as rear fuselage heat shields, wind deflectors, and tail covers. Since the 1960s, the use of titanium alloy moved from the rear fuselage to the middle fuselage, partially replacing structural steel to make important load-bearing components such as bulkheads, beams, and flap slides. The amount of titanium alloy used in military aircraft has increased rapidly, reaching 20% to 25% of the weight of the aircraft structure. Since the 1970s, civilian aircraft began to use titanium alloys in large quantities. For example, Boeing 747 passenger aircraft used more than 3,640 kilograms of titanium. Aircraft with a Mach number greater than 2.5 use titanium to replace steel to reduce structural weight. For another example, the US SR-71 high-altitude and high-speed reconnaissance aircraft (flying Mach number 3, flying height 26212 meters), titanium accounts for 93% of the weight of the aircraft structure, so-called "all-titanium" aircraft. When the thrust-to-weight ratio of the aero engine increases from 4-6 to 8-10, and the compressor outlet temperature increases from 200-300°C to 500-600°C, the original low-pressure compressor discs and blades made of aluminum must Zirconium oxide is used instead, or titanium alloy is used instead of stainless steel to make high-pressure compressor discs and blades to reduce structural weight.
