Ma ka moʻolelo nui o ka hana ʻana o nā mea hana kiʻekiʻe o kēia wā, ke kākau hou ʻia nei ka wehewehe ʻana o ka pololei. Mai nā ʻōniʻoni turbine i loko o nā mīkini aerospace a hiki i nā bearings pololei i loko o nā kaʻa ikehu hou, a i lalo i nā kaapuni microscopic o nā wafers semiconductor, ke ulu nei nā huahana ʻoihana i nā ʻano kikoʻī o ka pololei, ka lōʻihi, a me ka paʻakikī. Ma kēia kaʻina hana, ʻo ka loulou nānā, e hana ana ma ke ʻano he "puka kiaʻi" o ka kaohi maikaʻi, he mea nui loa ia. Eia nō naʻe, ʻaʻole lawa nā mea hana ana metala kuʻuna i ka wā e kū ai i nā ʻāpana hana o ka paʻakikī kiʻekiʻe, ka brittleness kiʻekiʻe, a i ʻole ka ultra-precision. Me nā holomua i ka ʻepekema mea, ke lawe nei nā mea hana ana keramika holomua i ke kahua me ka momentum i manaʻo ʻole ʻia. Me ko lākou mau waiwai kino kūikawā, ʻaʻole lākou e hoʻoponopono wale i nā wahi ʻeha o ka nānā kuʻuna akā hoʻokiʻekiʻe pū i nā kūlana o ka pololei o ka nānā ʻana i nā ʻoihana i kahi ana hou.
Ka Lanakila o ka Paʻakikī a me ke Kū'ē ʻana i ka Wear: Ke Ho'ākāka Hou nei i ke Ola o ka Mea Hana
Ma ke kahua o ka hana ʻana i ka pololei, ʻo ka ʻaʻahu ʻana o nā mea hana kekahi o nā kumu nui e alakaʻi ai i ka hōʻiliʻili ʻana o nā hewa ana. ʻO nā mea hana kila kuʻuna, e like me nā poloka ana, nā ana plug, a me nā ana apo, he paʻakikī ma kahi o HRC60 ma hope o ka mālama ʻana i ka wela. Ke hoʻopili pinepine kēia mau mea hana i nā ʻāpana hana me ka paʻakikī kiʻekiʻe—e like me nā kia carburized, nā mea ʻoki carbide, a i ʻole nā mea bearings seramika ponoʻī—e pau koke nā ʻili ana o nā mea hana. ʻO kēia ʻaʻahu pinepine ma ka pae micron, ʻike ʻole ʻia e ka maka ʻōlohelohe, akā no nā ʻāpana kikoʻī me nā hoʻomanawanui i kāohi ʻia ma ka pae micron a i ʻole sub-micron, he make ia ʻokoʻa.
Ua hoʻololi loa nā mea keramika holomua, ʻoiai hoʻi nā keramika zirconia a me alumina, i kēia hiʻohiʻona. ʻOi aku ka paʻakikī o ka keramika zirconia maʻemaʻe ma mua o 1200HV, ʻoi aku ka maikaʻi ma mua o ke kila kila maʻamau. ʻO ke ʻano kēia, he kiʻekiʻe loa ke kūpaʻa o nā ana keramika i ka ʻaʻahu ʻana, me ke ola ʻaʻahu pinepine he 10 mau manawa a ʻoi aku paha ma mua o nā ana kila. I ka nānā ʻana o ka pūʻulu o nā ʻāpana hana paʻakikī kiʻekiʻe, hiki i nā ana keramika ke mālama i ke kūpaʻa o ko lākou mau ana geometric no nā wā lōʻihi, e hōʻemi nui ana i ke alapine o ka recalibration a me ka pilikia o nā hewa ana i hoʻokumu ʻia e ka ʻaʻahu ʻana o ka mea hana. ʻO kēia hiki ke "ana i ka paʻakikī me ka paʻakikī" e lilo ai nā ana keramika i koho kūpono no ka nānā ʻana i ka carbide cemented, ke kila quenched, a me nā ʻāpana keramika holomua, e hōʻoia ana i ka hana hou ʻana a me ka hilinaʻi o ka ʻikepili nānā i ka wā lōʻihi o ka hoʻohana pinepine ʻana.
ʻAʻohe ʻūlū a me ka Inertness Kemika: ʻO ke Kahu Kūpono i nā Lumi Maʻemaʻe
ʻO nā wahi nānā ʻoihana hou, ʻoi aku hoʻi i ka semiconductor, nā mea lapaʻau, a me ka hana ʻana i nā ʻāpana optical, he mau koi koʻikoʻi loa ia no ka maʻemaʻe. ʻO ka nāwaliwali nui o nā ana metala kuʻuna aia i ko lākou hana kemika—he maʻalahi lākou e popo. I mea e pale aku ai i ka popo, pono pinepine nā ana kila i kahi uhi o ka ʻaila anti-rust. Eia nō naʻe, ʻo ke alo o kahi ʻili ʻaila ʻaʻole wale ia e hoʻololi i nā ana maoli o ke ana, e hoʻolauna ana i nā hewa ana, akā ʻoi aku ka nui, hiki i ka noe ʻaila a me nā ʻāpana ke hoʻohaumia i ke kaiapuni lumi maʻemaʻe a hoʻohaumia hoʻi i nā ʻili optical kiʻekiʻe a i ʻole nā wafers e nānā ʻia ana.
Loaʻa i nā mea keramika holomua ke kūpaʻa kemika kūlohelohe a ʻokoʻa. He pale loa lākou i ka popo, kū i ka pala waikawa a me ka alkali, a ʻaʻole pono ka pale ʻili ʻaila e mālama i ka maʻemaʻe o ka ʻili i nā wā lōʻihi i ka lewa. ʻO kēia ʻano "hoʻohana maloʻo" e hoʻolilo i nā ana keramika i koho makemake ʻia no nā wahi lumi maʻemaʻe. I ka nānā ʻana o ka wafer semiconductor a i ʻole ka hana ʻana o nā lens optical precision, ʻaʻole hoʻokuʻu nā ana keramika i nā hui organik volatile a ʻaʻole hoʻi e huki i ka lepo o ke kaiapuni. Eia kekahi, ʻo nā mea keramika he mea ʻole-magnetic, ʻo ia hoʻi, ʻaʻole lākou e huki i nā waihona hao a i ʻole nā ʻāpana magnetic i hana ʻia i ka wā o ka hana ʻana, no laila e hoʻopau loa i ka pilikia o nā mea hana ana a me ke kahakaha ʻana o ka workpiece i hoʻokumu ʻia e ka hoʻopili ʻana o nā mea haole. Hāʻawi kēia ʻano hoʻopili maʻemaʻe i kahi papa palekana paʻa no ka kaohi maikaʻi i ka hana kiʻekiʻe.
Paʻa Wela: Ke Heleuma e Kūʻē i nā Holoʻokoʻa Mahana Ambient
ʻO ka mahana ka mea hoʻololi nui loa e hoʻopilikia ana i ke ana pololei. Wahi a ke kumumanaʻo o ka hoʻonui ʻana a me ka hoʻemi ʻana o ka wela, neʻe nā ana o nā ana metala me nā loli o ka mahana ambient. ʻOiai ke kāohi pinepine ʻia nei nā keʻena metrology ma kahi mahana maʻamau o 20°C, ʻaʻole hiki ke pale ʻia nā loli o ka mahana i nā wahi hana maoli. Loaʻa i ke kila kahi coefficient hoʻonui wela ma kahi o 11.5 × 10⁻⁶/K, ʻo ia hoʻi, ʻoiai nā loli mahana minuke hiki ke alakaʻi i nā hewa dimensional pae micron.
I ka hoʻohālikelike ʻana, hōʻike nā mea keramika holomua i ke kūpaʻa wela kiʻekiʻe. ʻOi aku ka haʻahaʻa o ke koina hoʻonui wela o ka keramika alumina ma mua o ke kila, ʻo ia hoʻi ma lalo o nā loli mahana like, ʻoi aku ka liʻiliʻi o ka loli dimensional o nā ana keramika, e hoʻokokoke ana i ka "zero expansion." ʻAe kēia ʻano i nā ana keramika e hana maikaʻi loa ma mua o nā ana kila ma nā wahi hana mahana ʻaʻole mau, e hāʻawi ana i nā hopena ana kokoke i ka waiwai maoli. Eia kekahi, he haʻahaʻa ka conductivity thermal o nā keramika, ʻo ia hoʻi i ka wā o ka lawelawe lima ʻana, ʻoi aku ka lohi o ka wikiwiki o ka hoʻoili ʻana o ka mehana lima i ke ana, e hōʻemi ana i ka deformation thermal koke i hoʻokumu ʻia e ka mahana lima. ʻO kēia "insensitivity" i ke kaiapuni wela e hoʻolilo i nā ana keramika i alahaka kūpono e hoʻopili ana i nā kūlana lab metrology me nā noi papahele hana, e hoʻonui nui ana i ka pololei a me ke kūlike o ka nānā ʻana ma kahi.
ʻO ka pale ʻana a me ka māmā: Ke hoʻonui nei i nā palena o ka nānā ʻana
Ma waho aʻe o ka metrology dimensional, lawe mai nā ana keramika holomua i ka hana hou i ka hana uila a me ka ʻike hana. I ka nānā ʻana i nā ʻāpana uila, nā kikowaena pila, a i ʻole nā lako uila kiʻekiʻe, hoʻoweliweli nā ana metala i ka conductivity uila. ʻO ka hoʻopili ulia pōpilikia me kahi alakaʻi ola ʻaʻole hiki ke hōʻino wale i ka ana akā hiki ke hana i kahi kaapuni pōkole, e hōʻino ana i nā ʻāpana hana pipiʻi. He mau mea hoʻokaʻawale uila maikaʻi loa nā keramika; ʻo ka hoʻohana ʻana i nā ana keramika no ka nānā ʻana hiki ke uhaki kino i ke kaapuni conductive, e hāʻawi ana i ka palekana kūloko no ka nānā ʻana i nā huahana uila pololei.
I ka manawa like, ʻoi aku ka haʻahaʻa o ka nui o nā mea keramika ma mua o ke kila (ʻo ka zirconia ma kahi o 6.0g/cm³, ʻoiai ʻo ke kila he 7.8g/cm³). I ka hana ʻana i nā mea nānā nui, nā calipers, a i ʻole nā mea paʻa nānā automated, hiki i ka hoʻohana ʻana i nā mea keramika ke hōʻemi nui i ke kaumaha o ka mea hana. ʻAʻole wale kēia e hōʻemi i ka ikaika o ka hana no nā mea hoʻohana, e hōʻemi ana i nā hewa i hoʻoulu ʻia e ka luhi mai ka hoʻohana lōʻihi, akā e pōmaikaʻi pū kekahi i ka wikiwiki o ka neʻe ʻana a me ka pololei o ka pane ʻana o nā lima robotic automated. Ma nā laina nānā automated wikiwiki kiʻekiʻe, hiki i nā probes keramika māmā ke hōʻemi i ka hopena inertial, pale i nā mea ʻike pololei, a hoʻolōʻihi i ke ola o nā lako.
Hopena: Ka Lele ʻana mai ke Kōkua a i ke Kumu
I ka hōʻuluʻulu manaʻo, ʻaʻole wale nā mea hana ana keramika holomua he pani mea akā he kipi ʻenehana e pili ana i ka pololei o ka nānā ʻana. Hoʻokūkū lākou i ka ʻaʻahu me ka paʻakikī kiʻekiʻe loa, ka palaho me ka inertness kemika, nā ʻokoʻa mahana me nā coefficients hoʻonui haʻahaʻa, a me ka pilikia me ka insulation uila. I kēia manawa koʻikoʻi kahi e neʻe nei ka hana ʻana i ka hoʻomohala kiʻekiʻe a akamai, ʻo ka hoʻolauna ʻana i nā mea hana ana keramika holomua ʻaʻole ia he koho taktika e hoʻomaikaʻi i ka pololei o ka nānā ʻana a hoʻemi i nā kumukūʻai mālama, akā he neʻe hoʻolālā e hōʻoia i ka maikaʻi o ka huahana a hoʻonui i ka hoʻokūkū koʻikoʻi o ka ʻoihana. Me ka hoʻomau ʻana o ka ʻenehana hana keramika a me ka hoʻonui ʻana i ke kumukūʻai, loaʻa iā mākou ke kumu e manaʻoʻiʻo ai e pāʻani nā ana keramika i kahi kuleana koʻikoʻi i ka wā e hiki mai ana o ka metrology ʻoihana, e pale ana i ka pololei o "Hana ʻia ma Kina."
