Abstract
The present invention relates to a high-performance wear resistant ceramic nozzle and a making method thereof. The ceramic nozzle is made from the raw materials of 73% to 94.5% of silicon carbide and/or boron carbide, 5% to 25% of Al-Y series additive and 0.5% to 3% of CeO2 or La<2>O<3>. In the making method, the silicon carbide or boron carbide powder, Al-Y series additive, CeO2 or La2O3 powder are uniformly mixed and pressed into nozzle-shaped blanks; the blanks are put in a vacuum sintering furnace, the vacuum sintering furnace is vacuumized, and then argon is led into the vacuum sintering furnace; the temperature is raised for sintering. Since the components form silicon-aluminum-boron-yttrium composite phases with good toughness and wear resistance during mixing and sintering, the hardness, wear resistance and heat resistance performance of the nozzle are greatly increased, and the defects of the existing ceramic nozzles are overcome. The present invention has the advantages of reasonable design and great popularization value.
Description
Technical field:
The present invention relates to a kind of Wear-proof Porcelain Spray Nozzle And Manufacturing Approach.
Background technology:
Nozzles such as ceramic sand jet, oil nozzle adopt stupalith manufacturings such as silicon carbide, norbide or aluminum oxide more at present.Manufacturing technology adopts pressure sintering or pressureless sintering method.The subject matter that the nozzle of manufacturing exists is that wear resisting property is poor, work-ing life is low, also exist the poor toughness of nozzle simultaneously, easily the resistance to heat shocks of fragmentation and nozzle can satisfy defectives such as service requirements, for example oil nozzle open fire or when flame-out since Quench or sharp hot nozzle break easily.
Summary of the invention:
For solve ceramic nozzle hardness low, wear no resistance, the problem that work-ing life is low solves ceramic nozzle poor toughness, breakable problem simultaneously, and the manufacture method of a kind of ceramic nozzle and this nozzle is provided.The present invention realizes by following proposal: a kind of wear-resistant ceramic nozzle, and it is made by following raw material, and the mass percent of each material composition is as follows: silicon carbide and norbide 73%～94.5%, Al-Y are additive 5%～25%, CeO
2Or La
