In recent years, countries around the world are transforming from traditional ceramics to new types of ceramics. The trends and advantages of zirconia structural ceramics processing are worth our in-depth understanding.
Zirconia ceramics The toughness of zirconia ceramics is 4 times that of alumina ceramics, while zirconia can fall freely from a height of 1 meter, only some gaps will be broken, and zirconia ceramics have a high surface finish.
The market competition for the scientific research, development, design and application of structural ceramics is fierce and varies accordingly. In order to maintain the level of the aviation power industry in the 21st century, the aero-engine enterprises in the world of structural ceramic processing will look for new ways to improve the performance of military and civil diesel engines and maintain their market competitiveness. It is mirror glass, and the friction between it and the net is small, which can further improve the service life of the net, greatly reduce the net consumption, reduce the amount of current in the paper net, and reduce the power consumption.
Why must zirconia ceramics be machined with structural ceramics? Because the working temperature of the diesel engine is already very high. Another temperature rise can only be based on a detailed cooling and air supply design scheme or an increase in the number of air conditioners, but the actual effect of this method follows the law of decline and can only be based on the increase in the operating temperature of the raw materials. The fuel consumption can be increased and the torque can be obtained. The use of the saved high-pressure gas for refrigeration to the circulation system can also improve the torque and efficiency.
At present, the raw material of barrel rifling, the mainstream product of structural ceramic processing, is high-toughness carbon steel. This raw material has good ductility and ductility, and can withstand a variety of thermal expansion, cold shrinkage and laser cutting barrel rifling production processing. However, the main drawback is that the lack of hardness results in poor wear resistance. Whether it is a precision forged or cryogenically drawn barrel rifling, after rotation and movement, the rifling will be ground a little lower, and the entire barrel will eventually be scrapped.
