ʻO ka silikoni nitride ka mea hina hina me ka paʻakikī haʻihaʻi kiʻekiʻe, maikaʻi loa ka pale ʻana i ka haʻalulu wela, a me nā waiwai hiki ʻole ke hiki ke hoʻoheheʻe ʻia.
Ke hoʻohana nei i kēia mau hiʻohiʻona, ua hoʻopili ʻia i nā ʻāpana ʻenekini hoʻopau i loko e like me nā ʻāpana mīkini kaʻa, nā nozzles blowpipe mīkini welding, etc.
Me kona pale ʻaʻahu kiʻekiʻe a me ka ikaika mechanical kiʻekiʻe, e hoʻonui mau ana kāna mau noi i ka lawe ʻana i nā ʻāpana roller, rotating shaft bearings a me nā ʻāpana hana semiconductor.
Nā waiwai o nā seramika nitride silika
1, loaʻa ka ikaika kiʻekiʻe i kahi pae wela nui;
2, kiʻekiʻe haʻi paʻakikī;
3, ikaika kulou maikai;
4, kū'ē i ka luhi mechanical a me ka kolo;
5, māmā - haʻahaʻa haʻahaʻa;
6, kiʻekiʻe paʻakikī a ʻaʻahu kūʻē;
7, maikaʻi loa thermal haʻalulu kū'ē;
8, hoʻonui wela haʻahaʻa;
9, insulator uila;
10, maikaʻi oxidation kū'ē;
11, maikaʻi kemika corrosion kū'ē.
He haʻahaʻa haʻahaʻa ka hoʻonui ʻana o ka wela a me ka conductivity thermal kiʻekiʻe, no laila, loaʻa iā lākou ke kūpaʻa haʻalulu wela. ʻAʻole e haki ka nitride silicon sintered wela ma hope o ka wela ʻana i 1000 ℃ a hoʻokomo i loko o ka wai anuanu. ʻAʻole kiʻekiʻe loa ka mahana, silicon nitride ka ikaika kiʻekiʻe a me ka hopena o ka hopena, akā ma luna o 1200 ℃ e hōʻino ʻia me ka ulu ʻana o ka manawa hoʻohana, i hoʻemi ʻia kona ikaika, ʻoi aku ka nui o ka pōʻino luhi ma luna o 1450 ℃, no laila ka hoʻohana ʻana. ʻAʻole ʻoi aku ka nui o ka mahana o Si3N4 ma mua o 1300 ℃.
No laila, ua hoʻohana nui ʻia ka silicon nitride i:
1. Ka poepoe wili a me ka huila;
2. Nā mea ʻenekini: valve, rocker arm pad, sealing surface;
3. Induction pumehana coil bracket;
4. Nā pahi turbine, nā pahi, nā bākeke;
5. ʻO ka wiliwili a me ka hoʻopaʻa ʻana i ka brazing;
6. Hui mea hoʻomehana;
7. Welding positioner;
8. ʻO nā lāʻau pololei a me nā lima lima ma nā wahi lole kiʻekiʻe;
9. Puu me ka paipu Thermocouple;
10. Nā lako hana semiconductor.
