(Silicon Nitride BallE hlahisoa keWintrustek)

Silicon nitridehangata e sebelisoa e le karolo ea bohlokoa ea ho sila li-rotor, media media, le li-turbine. Lihlahisoa tse entsoeng ka silicon nitride li na le boima bo lekanang lezirconiaha li bapisoa le lisebelisoa tse tloaelehileng, empa li boetse li na le boima bo phahameng le ho apara ho fokolang.

Setšoantšo sa Si3N4 bolo ea ho sila's matla mogote botsitso etsa hore ho loketse ho sebelisoa ka phahameng-thempereichara le cryogenic ho sila dithulaganyo. Ho hanyetsa mocheso o ikhethang oa bolo ho e lumella ho mamella liphetoho tse matla tsa mocheso ntle le ho lahleheloa ke ts'ebetso kapa sebopeho sa eona. E bobebe ho feta tšepe ka 60%, e hola ka mokhoa o fokolang, 'me e na le litšenyehelo tse tlase kaofela ha ho bapisoa le lisebelisoa tse ling tsa ho sila. Ka lebaka la boima ba eona bo boholo, e khona ho mamella litlhoko tsa mekhoa e mengata ea ho hloekisa phofo ea tšepe le ho senya. Ha ho hlokahala boima bo phahameng, tšilafalo e fokolang, le ho khopa ho fokolang, ona ke mokhoa o phethahetseng oa ho sila.

Thepa

• Matla a phahameng

• Ho hanyetsa ho hotle ho apara le ho senya

• Ho mamella mocheso o phahameng

• Tšireletso ea motlakase

• Lintho tse seng tsa makenete

Melemo ea mantlha ea silicon nitride ho feta libolo tsa tšepe:

1. Ka lebaka la boima ba eona bo nyane ka 59% ho feta bolo ea tšepe, e fokotsa haholo ho thetheha, matla a centrifugal, le moaparo oa mabelo ha bere e matha ka lebelo le holimo;

2. Kaha elasticity modulus e kholoanyane ka 44% ho feta ea tšepe, deformation e nyane haholo ho feta ea bolo ea tšepe;

3. HRC e 78, 'me ho thatafala ho feta ha tšepe;

4. Ho khohlana ho honyenyane, ho kenya motlakase, ho se sebetse ka makenete, le ho hanyetsa ho bola ha lik'hemik'hale ho feta tšepe;

5. The material's coefficient of thermal expansion is 1/4 of that of steel, making it resistant to abrupt temperature changes;

6. RA e ka fihla ho 4-6 nm, e leng ho etsang hore ho be bonolo ho fihla sebakeng se batlang se se na sekoli;

7. Ho hanyetsa mocheso o matla, ho 1050℃, bolo ea silicon nitride ceramic e boloka matla a eona a babatsehang le ho thatafala;

8. E khona ho sebetsa ntle le ho tlotsa oli 'me ha ho mafome.
