Silicon nitride bụ seramiiki isi awọ nke nwere mgbaji siri ike dị elu, nkwụsi ike ujo dị mma, yana ihe na-enweghị atụ na ọla gbazere.
N'iji njirimara ndị a, a na-etinye ya n'ime akụkụ engine combustion dị n'ime ya dị ka akụkụ engine ụgbọ ala, igwe ịgbado ọkụ na-afụ ụfụ, wdg, karịsịa akụkụ ndị dị mkpa iji mee ihe na gburugburu ebe dị njọ dị ka ikpo ọkụ.
Site na nguzogide ya dị elu na ike ọrụ dị elu, ngwa ya na-ebu akụkụ ndị na-akpụ akpụ, na-atụgharị aro bearings na semiconductor mmepụta akụrụngwa akụrụngwa na-agbasawanye mgbe niile.
Njirimara nke seramiki silicon nitride
1, nwere ike dị elu na oke okpomọkụ;
2, nnukwu mgbaji siri ike;
3, ike na-ehulata nke ọma;
4, iguzogide n'ibu ike ọgwụgwụ na creep;
5, ìhè - obere njupụta;
6, ike siri ike na iyi nguzogide;
7, nke ọma thermal ujo eguzogide;
8, obere mgbasawanye thermal;
9, ihe mkpuchi eletrik;
10, ezigbo mgbochi oxidation;
11, mma chemical corrosion eguzogide.
Silicon nitride ceramics nwere ọnụọgụ mgbasawanye ọkụ dị ala yana ịdị elu thermal conductivity, yabụ na ha nwere ezigbo nguzogide ujo. silicon nitride nke na-ekpo ọkụ na-ekpo ọkụ agaghị agbaji ma kpoo ọkụ ruo 1000 ℃ ma tinye ya na mmiri oyi. Na ọ bụghị oke elu a okpomọkụ, silicon nitride nwere nnukwu ike na mmetụta na-eguzogide, ma n'elu 1200 ℃ ga-emebi na uto nke ojiji oge, nke mere na ike ya na-ebelata, ọzọ adịkarịghị ike ọgwụgwụ mmebi n'elu 1450 ℃, otú ojiji. nke Si3N4 okpomọkụ n'ozuzu adịghị gafere 1300 ℃.
Ya mere, silicon nitride ejirila ọtụtụ ebe na:
1. Bọọlụ na-atụgharị na agba agba;
2. Akụrụngwa engine: valvụ, ogwe aka rocker, akara akara;
3. Induction kpo oku eriri igwe;
4. Turbine agụba, agụba, bọket;
5. Ịgbado ọkụ na brazing;
6. Mgbakọ ihe ọkụ;
7. Welding positioner;
8. Oghere dị mma na aka uwe na gburugburu akwa akwa;
9. Thermocouple n'ọbọ na tube;
10. Semiconductor usoro akụrụngwa.
