Abstract

The invention relates to a thread machining method, in particular to a ceramic-based composite thread machining method. The technical problems that an existing ceramic-based composite material thread machining method is poor in thread quality, poor in thread machining quality stability, short in thread service life and the like are solved. The thread machining method comprises the following steps: 1) weighing rosin, alum and boron carbide powder according to a certain mass ratio; 2) adding the rosin and the alum into a container, heating until the rosin and the alum are completely melted, then adding the boron nitride powder, and heating until a viscous glue solution is formed; (3) the ceramic-based composite part is polished, cleaned and dried; (4) the to-be-machined thread part is coated with a glue solution; (5) thread machining is conducted after the glue solution is cured; (6) the ceramic-based composite part obtained after thread machining is completed is subjected to high-temperature treatment, and the glue solution is removed; and (7) silicon carbide coating deposition is conducted on the surface of the ceramic-based composite part, and the completely-machined ceramic-based composite part is obtained.

Description

technical field [0001] The invention relates to a thread processing method, in particular to a ceramic matrix composite material thread processing method, which is mainly used in the field of high-strength, oxidation-resistant and high-temperature-resistant fiber-reinforced composite material thread processing. Background technique [0002] Ceramic matrix composite is a multifunctional material that combines the performance advantages of metal materials, ceramic materials and carbon materials. Sensitivity and no catastrophic damage, etc., have a wide range of applications in aviation, aerospace, satellite aerospace, nuclear energy and photovoltaics. [0003] Due to the limitation of the weaving and molding technology of ceramic matrix composites, the preforms of ceramic matrix composites are mostly two-dimensional layup (carbon fiber / silicon carbide fiber), 2.5D weaving, three-dimensional acupuncture (carbon fiber), fine weaving puncture (carbon fiber) etc., it is difficult...
