不同陶瓷材料的运用-找广东夏阳精细陶瓷科技有限公司咨询
来源:原创 | 作者:XYC | 发布时间: 2020-12-25 | 867 次浏览 | 分享到:
氧化锆不仅具有高硬度,高耐磨性,也是精细陶瓷中韧性非常好的材料,因此它常用
于结构件,耐磨件。它还具有与钢材接近的热膨胀系数,因此也是常用于连接陶瓷和
钢的材料.

(Si3N4)

它的微观结构由互锁成微棒的细长晶体组成,其互相结合成微棒。优异的耐磨

性能,优异的断裂韧性以及非常高的热稳定性,使得氮化硅陶瓷用于轻、高速

和高精度的轴承,以及重型陶瓷成形工具和汽车部件承受高应力的滚珠和滚动

元件,并且在焊接工艺中利用良好的耐热冲击性和耐高温性。

he microstructure consists of elongated crystals that interlock into micro-rods. Silicon

nitride ceramics has excellent wear resistance, outstanding fracture toughness and good

thermal stability. Its these features that make it suitable for applications as following:

Light bearings; high-speed bearings, high precision bearings , tools for heavy-type

ceramic forming, automotive components subject to high stress.And the good thermal

shock resistance and high temperature resistance is exploited in welding processes.

应用领域:

◆机械行业(电机轴承、电主轴)          

◆冶金行业(焊接辊、阻水圈)                    

◆汽车部件(涡轮转子、凸轮挺杆)      

◆工业耐磨件(金属成型、剪切刀具,喷砂喷嘴)

◆航天、航空      ◆半导体

Application areas :

碳化硅(SiC)

碳化硅几乎像钻石一样。 它不仅是最轻的,也是最硬的陶瓷材料,具有优异

的导热性,低热膨胀性,非常耐酸和碱,并且在急冷急热的环境下不易崩裂。

Silicon carbide behaves almost like a diamond.
It is not only the lightest, but also the hardest

ceramic material and has excellent thermal conductivity,
low thermal expansion high

resistant to acids and lyes and
its not crack easily in the enviroment of sudden cold or hot.

应用领域:







◆石油(阀门、喷嘴)   
◆化工(密封件)

◆机械行业(轴承、滚珠)            

◆航天(燃汽涡轮机叶片,涡轮增压器转子)
