Hlau - Cov txheej txheem Ceramin
Tus tub ntxhais yog kom ua tiav kev sib txuas ntawm cov hlau thiab cov kab sib txuas nrog "batchamas ntawm" batching → sintering → Sintering ", txhim kho kev txhuam tawm ruaj khov thiab hnav tsis kam.
Cov khoom siv nyoos cov khoom lag luam:
Pawg: Cov hmoov sib xyaw ntawm Ni, Al, thiab CR (CR (CR (CR (CR (CR (AS 18), ua rau 40-55% ntawm tag nrho cov qauv.
Tej hub Theem: Sau ntawm ti₂ (30-35%), al₂o₃ (20-25%), zu-crystal system hmoov nrog qhov sib npaug ntawm 6.25-6.27), suav rau 35-40% ntawm tag nrho.
Phau ntawv: Suav nrog cov feem ntau ua feem los pab hauv kev ua si.
Nws:
Cov hmoov hlau, cov hmoov nplej sib xyaw, thiab cov phau ntawv sib xyaw ua ke nyob rau hauv cov kev sib piv los kom ntseeg tau tias cov khoom sib faib sib xyaw.
Compression Moulding:
Cov khoom siv sib xyaw tau muab tso rau hauv cov pwm thiab nias hauv qab lub siab ntawm 245-255 MPa los ua ib lub disc {2} zoo li lub cev ntsuab.
Sintering kev kho mob:
Lub cev ntsuab hloov mus rau ib qho sintering rauv, uas muaj kev tuav siab ntawm 1.4-1.6 MPA tswj hwm. Qhov ntsuas kub tau tsa mus rau 780-850℃thiab tuav rau 2.5-3.0 teev.
Kub -} Nias xovxwm sinsing fuses fuses cov qauv hlau thiab tej hub sib xyaw ua ke, thermal conductivity, thiab lub zog kho tshuab.
