Ke kūpaʻa oxidation o nā ʻāpana keramika pololei a me kona ʻano noi
ʻO nā ʻāpana keramika kikoʻī he mau mea hana kiʻekiʻe pono ʻole i ka ʻoihana hou, a ʻo ko lākou mau waiwai kino a me ke kemika kū hoʻokahi i lawe mai i nā loli kipi i nā ʻano he nui. I waena o lākou, ʻo ke kūpaʻa ʻana i ka oxidation kekahi o nā hiʻohiʻona koʻikoʻi o nā ʻāpana keramika kikoʻī, he mea nui loa ia i nā ʻano ʻino loa.
Ke kūpaʻa ʻokikene o nā ʻāpana keramika pololei
ʻO nā mea keramika kikoʻī, e like me ka alumina, silicon nitride, silicon carbide, a me nā mea ʻē aʻe, ua ʻike ʻia no ko lākou mau waiwai antioxidant maikaʻi loa. Hiki i kēia mau mea ke mālama i nā waiwai kemika paʻa ma lalo o ke ana wela kiʻekiʻe a me ke kaiapuni oxidation kiʻekiʻe, a ʻaʻole maʻalahi ke pane me ka oxygen, no laila e pale aku ai i ka oxidation, ka pala a me ka hōʻino ʻana o ka hana o ka mea. ʻO kēia kūpaʻa oxidation maikaʻi loa ma muli nui o ke ʻano kristal paʻa a me ka ikaika o nā pilina kemika i loko o ka mea keramika, ka mea e hiki ai ke mālama i ka paʻa a me ka hilinaʻi lōʻihi i nā kaiapuni ʻino.
Kaiapuni noi koʻikoʻi
1. Lewa
Ma ke kahua aerospace, he mea nui loa ke kūpaʻa ʻana o ka oxidation o nā ʻāpana keramika kikoʻī. Pono nā ʻenekini mokulele a me nā mokulele e kū i nā mahana kiʻekiʻe loa a me nā kinoea oxidizing i ka wā lele wikiwiki. Hiki i nā ʻāpana e like me nā keʻena kuni, nā nozzles a me nā turbines i hana ʻia me nā mea keramika kikoʻī ke mālama i ka hana paʻa i nā mahana kiʻekiʻe, pale pono i ka oxidation a me ka corrosion, a hōʻoia i ka hana maʻamau o ka ʻenekini a me ka mokulele.
2. ʻĀpana ikehu
Ma ke kahua o ka ikehu, he kuleana koʻikoʻi nō hoʻi ke kūpaʻa ʻana o ka oxidation o nā ʻāpana keramika pololei. No ka laʻana, i nā lako wela kiʻekiʻe e like me nā turbine kinoea a me nā paila lanahu, hiki i nā ʻāpana e like me nā papa insulation thermal a me nā kānana i hana ʻia me nā mea keramika ke pale aku i ka ʻino ʻana o ka uahi wela kiʻekiʻe, pale i ke ʻano o loko o nā lako a hoʻomaikaʻi i ka pono o ka ikehu. Eia kekahi, ma ke kahua o ka ikehu nukelea, hoʻohana nui ʻia nā mea keramika pololei i ka insulation thermal a me ka papa pale o nā reactors nukelea e hōʻoia i ka hoʻohana palekana ʻana i ka ikehu nukelea.
3. ʻOihana kemika
I loko o ka ʻoihana kemika, pono e hoʻokō ʻia nā hopena kemika he nui a me nā kaʻina hana i nā wahi wela kiʻekiʻe, kaomi kiʻekiʻe a me nā wahi ʻino ikaika. ʻO nā ʻāpana keramika kikoʻī, me ko lākou kūpaʻa maikaʻi loa i ka oxidation a me ke kūpaʻa i ka corrosion, he mau mea pono ʻole ia i kēia mau wahi. No ka laʻana, i nā lako kemika me ka ʻino nui o ka waikawa a me ka alkali, hiki i nā ʻāpana e like me nā paipu, nā valves a me nā pamu i hana ʻia me nā mea keramika ke pale pono i ka corrosion a me ka leakage, e hōʻoiaʻiʻo ana i ka palekana a me ke kūpaʻa o ka hana kemika.
hopena
I ka hōʻuluʻulu manaʻo, ʻo ke kūpaʻa ʻana o ka oxidation o nā ʻāpana keramika kikoʻī kekahi o kona mau waiwai maikaʻi loa, kahi e pāʻani ai i kahi kuleana koʻikoʻi i nā ʻoihana aerospace, ikehu a me nā kemika. Me ka holomua mau o ka ʻepekema a me ka ʻenehana a me ka hoʻonui mau ʻana o nā noi, e hoʻomau ka hopohopo a me ka hoʻomaikaʻi ʻana i nā waiwai antioxidant o nā ʻāpana keramika kikoʻī, e lawe mai ana i ka hana hou a me ka holomua i nā kahua hou aʻe. I ka wā e hiki mai ana, me ka hoʻomohala mau ʻana o ka ʻepekema mea a me ka ʻenehana hoʻomākaukau, loaʻa iā mākou ke kumu e manaʻoʻiʻo ai e hōʻike nā ʻāpana keramika kikoʻī i ko lākou ʻano hoʻohiwahiwa a me ka waiwai kū hoʻokahi ma nā kahua hou aʻe.
