Mu nganda zikomeye nko mu nganda zikora indege n'ubushakashatsi ku bikoresho bigezweho, ndetse na mikoroni imwe y'ibipimo ishobora kwangiza umutekano, imikorere, cyangwa icyemezo. Uko ibidukikije birushaho kwiyongera - haba mu turemangingo tw'ibizamini bya moteri y'indege cyangwa mu byumba bisukura ibyuma kuri dogere selisiyusi 500 - imbogamizi z'ibikoresho bisanzwe byo gupima ibyuma zigaragara neza. Shyiramo ibikoresho bya ceramic bitunganye: byakozwe kugira ngo bihamye aho ibyuma bihindagurika.
Ikibazo cy'ubushyuhe: Impamvu ibyuma bigwa nabi
Ibipimo bisanzwe by'icyuma, harimo n'ubwoko bwa alloy ikomeye cyangwa ubwoko bwa chrome-plated, bigaragaza coefficient of thermal expansion (CTE) ya hafi 11–12 ppm/°C. Mu gihe ubushyuhe buhindagurika bwa ± 10°C gusa—ibintu bikunze kugaragara ku igorofa ry'amaduka hafi y'amatanura cyangwa muri laboratwari zihindagurika mu mihindagurikire y'ikirere—ibi bishobora gutuma uburebure burenga µm 1 kuri mm 100, bigahungabanya mu buryo butaziguye uburyo ubushyuhe buhagaze mu gikoresho cyo gupima.
Byongeye kandi, kumara igihe kirekire uhura n'ubushyuhe bwinshi byihutisha ogisijeni, mu gihe ubushyuhe butera umunaniro mu miterere y'ibintu, bigatera guhindagurika burundu. Ku bagenzuzi b'ibice by'indege bagenzura ubushobozi bw'ibyuma bya turbine cyangwa imiterere y'icyumba cyo gutwika, uku kudahuzagurika ntikwemerwa.
Ibikoresho bya Ceramic by'ubuhanga: Byakozwe mu rwego rwo kwirinda imihindagurikire y'ikirere
Ibikoresho bya zhhimg by’ubuziranenge bw’ubutare, bishingiye ku butare bwa alumina bufite isuku nyinshi (95% na 99% bya Al₂O₃ formulations), bitanga CTE iri hagati ya 6–8 ppm/°C—hafi 40% iri munsi y’icyuma. Ikirenzeho, imyitwarire yabyo yo kwaguka ni iy’umurongo ugororotse kandi ishobora guhinduka, bigatuma ingano zisubiramo mu bihe by’ubushyuhe bisubirwamo.
Ariko guhagarara neza kw'ubushyuhe ni intangiriro gusa:
- Kutagira ingese: Bitandukanye n'icyuma, alumina ceramic ntishobora kwangizwa n'ubushuhe, aside, alkali, na oxidation—ndetse no mu bushyuhe bwinshi.
- Ntikoresha ingufu za rukuruzi cyangwa amashanyarazi: Ni nziza cyane muri laboratwari zigenzura imiterere y'amashanyarazi cyangwa uduce duto tw'amashanyarazi.
- Ubukomere kugeza kuri 15.2 GPa: Irinda kwangirika bitewe no gukoraho kenshi, ikomeza ubuziranenge bwo gupima mu gihe cy'imyaka myinshi ikoreshwa.
- Gutuza mu buryo bw'igihe kirekire: Nta ngaruka zo gusaza cyangwa kuruhuka mu mibabaro, ni ingenzi cyane ku bipimo ngenderwaho mu mashami yo gupima.
Kwemeza Isi Nyayo: Kuva muri Laboratwari kugeza kuri Launchpad
Umucuruzi ukomeye mu by’indege wo mu cyiciro cya mbere (Tier 1) aherutse gusimbuza ibyuma bipima ubushyuhe n’ibikoresho bya zhhimg bya alumina 99% bya ceramic kugira ngo bigenzurwe ibice bya turbine bya nickel-alloy. Bakorera ahantu hagenzurwa kandi hahindagurika cyane ho ± 8°C, bavuze ko bagabanutseho 62% mu kwangwa kudashobora kwihanganira bitewe n’ihindagurika ry’ubushyuhe bw’ubushyuhe—bivamo ko umusaruro wihuta cyane ndetse n’ibice bike bihenze cyane by’ibisigazwa.
Mu buryo nk'ubwo, laboratwari zikoresha ibikoresho bishyuha cyane ubu zikoresha ibipimo bya ceramic ring gauges na plug gauges kugira ngo zemeze nyuma y'ubushyuhe bw'imashini zikora matrix (CMCs), aho ibikoresho by'icyuma byahinduraga cyangwa bikanduza ingero.
Impamvu Guhitamo Ibintu ari icyemezo cyo gupima
Guhitamo igikoresho cyo gupimisha si ukumenya neza gusa—ni ukumenya neza igihe umuntu atangiye gushyuha. Mu bihe bikomeye cyangwa bihindagurika, igikoresho cyo gupimisha gipima neza gitanga inyungu zifatika mu kwizera amakuru, kubahiriza amategeko, n'ikiguzi cyose cy'umutungo.
Muri zhhimg, dutunganya buri gipimo cya alumina ceramic kugira ngo gihuze n'ibipimo bya ISO 3650 na JJG 146, hamwe n'ibyiciro byihariye biboneka ku bikoresho bishyushye cyane cyangwa bisukuye cyane.
Ku bijyanye na zhhimg
zhhimg ni umuyobozi ku isi mu bice bigezweho by’ubuziranenge mu nganda zisaba imbaraga nyinshi. Ibikoresho byacu bya ceramic bitanga ubuziranenge—byakozwe muri ceramic ya alumina ya 95% na 99%—bitanga ubushyuhe burambye, kurwanya ingese, no kuramba mu bikoresho by’indege, ingufu, n’ubushakashatsi bwa siyansi.

Hamagara zhhimg uyu munsi kugira ngo usabe raporo yo kugereranya imikorere y'ubushyuhe cyangwa seti y'icyitegererezo cy'ibibazo byawe byo gupima ubushyuhe bwinshi.
