SiC whisker toughened Si3N4 ceramic pneumatic motor blade, preparation method and pneumatic motor
The invention discloses a SiC whisker toughened Si3N4 ceramic pneumatic motor blade, a preparation method and a pneumatic motor, and relates to the technical field of ceramic materials. The ceramic blade is prepared from the following raw materials: Si3N4 ceramic base powder, SiC whiskers, Y2O3, Al2O3 and epoxy resin. The pneumatic motor blade is made of the Si3N4 ceramic material instead of an existing metal material, the density is low, the total weight of a motor product can be fully reduced, and the pneumatic motor blade has the advantage of being lighter in load; according to the ceramic pneumatic motor blade disclosed by the invention, SiC whiskers are also added to carry out toughening modification on the material, so that the ceramic blade has the characteristics of higher bending resistance, more compact texture and higher wear resistance; the defects of low blade strength and poor toughness in the existing pneumatic motor are effectively improved, and the service life of the blade is prolonged. According to the preparation method provided by the invention, a selective laser sintering (SLS) technology is adopted to prepare the Si3N4 ceramic blade biscuit, and a ceramic component with a complex appearance is rapidly formed.
本发明公开了一种SiC晶须增韧Si3N4陶瓷气动马达叶片、制备方法及气动马达，涉及陶瓷材料技术领域。陶瓷叶片的原材料由以下组分组成：Si3N4陶瓷基粉，SiC晶须，Y2O3，A12O3，以及环氧树脂。本发明采用Si3N4陶瓷材料替代现有金属材料制成气动马达叶片，密度较低，可以充分减少马达产品总重量，具有更轻载的特点；本发明的陶瓷气动马达叶片还加入了SiC晶须对材料进行增韧改性，使得陶瓷叶片具有更耐抗弯、质地更致密、更耐磨的特性；有效改善现有气动马达中的叶片强度低、韧性差的不足，提高叶片使用寿命。本发明提供的制备方法，采用激光选区烧结(SLS)技术制备Si3N4陶瓷叶片素坯，快速成型出具有复杂外形的陶瓷构件。
