Product Description

air pressure thermal shock resistant Si3N4 bar stick

Reputation depends on quality, quality comes from Hard!


Silicon Nitride Ceramic:

Liquid phase sintering is to add A1203 and Y 203 to the silicon carbide powder. After molding, it is sintered at 1800 °C to 2000 y. In the sintering process, A1z team and Y203 form eutectic compound YAG (aluminum garnet Y3Ali [ )) melting point 1760 ° C), the appearance of liquid phase promotes the sintering of Sic and reduces the sintering temperature. Abrasive water jet drilling ceramic technology research compared with cutting processing, drilling processing does not need to consider the influence of nozzle feed rate, processing There are two main problems in the process of relatively simple drilling processing: one is the control of the roughness of the hole wall and the size of the hole; the other is that due to the divergence of the abrasive water jet, the hole formed by the machining will have a certain degree of inclination. Wan Qingfeng Through experiments, it can be concluded that the larger jet pressure, smaller nozzle traverse speed and proper abrasive flow can effectively increase the drilling depth and improve the quality of the hole wall. However, due to the jet divergence, the hole wall presents a certain taper and points. For the smooth drilling area and the deformation wear area, when the hole being machined is a blind hole, the bottom part will be blocked by the [water pad", and the bag-like structure will be formed. The mathematical method is used to establish the prediction model of drilling depth and surface roughness of the hole wall. The research status and progress of the abrasive water jet processing ceramics respectively. The abrasive holes can be used to ream the existing holes. However, there is no relevant research literature in China. Subsequent research can be applied to the research of reaming processing technology to further broaden the application of abrasive water jet drilling.

properties:

High hardness, high strength, wear resistance, corrosion resistance, high temperature(1200°), good thermal diffusivity, good thermal shock resistance(avoid the temperature changing rapidly), good insulativity, low density. The comprehensive properties are best in most of structure ceramic.
