Nnyocha nke agụba injin aero nwere nnukwu ihe achọrọ maka nkwụsi ike, izi ezi na ntụkwasị obi nke ikpo okwu ahụ. Ma e jiri ya tụnyere ikpo okwu nyocha ọdịnala dịka ígwè a kpụrụ akpụ na alloy aluminom, ikpo okwu granite na-egosi uru ndị a na-apụghị ịgbanwe agbanwe na ọtụtụ ihe ngosi dị mkpa.
I. Nkwụsi Ike nke Okpomọkụ: "Ihe Nchedo Eke" Megide Mgbochi Okpomọkụ
Oke mgbasawanye okpomọkụ nke ikpo okwu ígwè a kpụrụ akpụ dị ihe dịka 10-12 × 10⁻⁶/℃, nke alloys aluminom dịkwa elu ruo 23 × 10⁻⁶/℃. N'okpuru okpomọkụ nke ọrụ nke ngwaọrụ nchọpụta ma ọ bụ mgbanwe na okpomọkụ gburugburu ebe obibi na-emepụta, mgbanwe nha na-adịkarị mfe ime, na-eduga na njehie nchọpụta. Oke mgbasawanye okpomọkụ nke ikpo okwu granite bụ naanị (4-8) × 10⁻⁶/℃. N'ime mgbanwe okpomọkụ nke ± 5℃, mgbanwe nha nke ikpo okwu granite nke mita 1 dị obere karịa 0.04μm, nke a pụrụ ileghara anya. Njirimara mgbasawanye okpomọkụ a dị oke ala na-enye elu ntụaka kwụsiri ike maka akụrụngwa ziri ezi dị ka laser interferometers na igwe nha nhazi atọ, na-ezere ntụgharị nha nke nhazi agụba nke mgbanwe okpomọkụ kpatara.

Ii. Arụmọrụ Mgbochi Mkpọchi: "Ihe Mgbochi Dị Irè" Maka Iwepụ Mgbochi Mkpọchi
N'ebe a na-arụ ọrụ n'ụgbọelu, mkpọtụ gburugburu ebe obibi nke ọrụ nke ngwaọrụ igwe na mmegharị nke ndị ọrụ na-akpata na-abụkarị. Ikpo okwu alloy aluminom enweghị ike siri ike, ikpo okwu ígwè a kpụrụ akpụ enweghịkwa arụmọrụ dị ala nke na-eme ka ọ sie ike igbochi mkpọtụ nke ọma. Ọdịdị kristal dị n'ime ikpo okwu granite na-enye ya njirimara dị mma nke na-ebelata mmiri, yana oke mmiri nke 0.05-0.1, nke bụ okpukpu ise nke ígwè a kpụrụ akpụ na okpukpu iri nke aluminum alloy. Mgbe a na-ebufe mkpọtụ mpụga na ikpo okwu ahụ, ọ nwere ike ibelata ike mkpọtụ site na ihe karịrị 90% n'ime sekọnd 0.3, na-eme ka ngwa nchọpụta ahụ nwee ike iwepụta data ziri ezi na gburugburu ebe a na-ama jijiji.
Iii. Nkwụsi ike na Nguzogide iyi: "Ebe siri ike siri ike" nke na-eme ka o doo anya na ọ ga-adịru ogologo oge.
Mgbe ejiri ya ruo oge ụfọdụ, ikpo okwu ígwè a kpụrụ akpụ na-enwe ike ịgbawa ike ọgwụgwụ, nke na-emetụta izi ezi ya. Ikpo okwu ígwè aluminom nwere obere ike na enweghị ike iyi ya nke ọma, nke na-eme ka o sie ike ịnagide ojiji ngwa nyocha siri ike ugboro ugboro. Njupụta nke ikpo okwu granite ruru 2.6-2.8g /cm³, ike nrụgide ya karịrị 200MPa, ike Mohs ya dịkwa 6-7. Mgbe a na-etinye ibu dị arọ na esemokwu ogologo oge site na ngwa nyocha agụba, ọ naghị adị mfe iyi ma ọ bụ gbanwee. Data sitere na ụlọ ọrụ ụgbọelu ụfọdụ na-egosi na mgbe ejiri ya ruo afọ asatọ, mgbanwe dị larịị nke ikpo okwu granite ka na-achịkwa n'ime ±0.1μm/m, ebe ikpo okwu ígwè a kpụrụ akpụ kwesịrị ịgbanwegharị mgbe naanị afọ atọ gasịrị.
Iv. Nkwụsi Ike Kemịkalụ: "Nkuku Isi Iguzosi Ike" Maka Imeghari Gburugburu Dị Mgbagwoju Anya
A na-ejikarị ihe ndị na-emepụta kemịkalụ dịka ihe nhicha na mmanụ na-eme ihe n'ebe a na-enyocha ụgbọelu. Ikpo okwu alloy aluminom na-adịkarị mfe ire ere, ikpo okwu ígwè a kpụrụ akpụ nwekwara ike imetụta izi ezi ya n'ihi oxidation na nchara. Granite nwere mineral dịka quartz na feldspar. O nwere ihe ndị na-eme ka kemịkalụ sie ike, pH na-anabata ya site na 1 ruo 14, ọ nwekwara ike iguzogide mbibi nke ihe kemịkalụ nkịtị. Enweghị mmiri ozuzo ígwè n'elu ya, na-eme ka gburugburu ebe a na-achọpụta ihe dị ọcha ma na-ezere mmejọ nha nke mmetọ kemịkalụ kpatara.
V. Ịhazi Nhazi: "Isi Dị Mma" maka nha ziri ezi
Site na teknụzụ dị oke nkenke dịka magnetorheological polishing na nhazi ion beam, ikpo okwu granite nwere ike nweta izi ezi nhazi nke ±0.1μm/m maka ịdị larịị na Ra≤0.02μm maka ịdị larịị, karịa nke ikpo okwu ígwè a kpụrụ akpụ (±1μm/m maka ịdị larịị) na ikpo okwu alloy aluminum (±2μm/m maka ịdị larịị). Elu a dị elu na-enye ntụaka nrụnye ziri ezi maka sensọ dị elu na nyocha nha, na-eme ka mmezu nke nha nhazi atọ nke agụba injin aero-injin na ọkwa 0.1μm.
N'ọnọdụ dị elu nke inyocha agụba injin aero, ikpo okwu granite, yana uru zuru oke ha na nkwụsi ike okpomọkụ, iguzogide ịma jijiji, nkwụsi ike, nkwụsi ike kemịkalụ na izi ezi nhazi, abụrụla nhọrọ kacha mma iji hụ na nyocha ziri ezi na ntụkwasị obi, na-etinye ntọala siri ike maka mmepe dị elu nke mmepụta ụgbọ elu.
