Nitinol waya: chinhu chitsva cheindasitiri yemazuva ano uye mushonga
2024-06-19 10:00:00
Mundima yemazuva ano iri kukurumidza kusimukira yesainzi uye tekinoroji, NiTi waya, semhando yehungwaru alloy zvinhu ine yakasarudzika zvivakwa, zvishoma nezvishoma inogamuchira kutariswa kwakafara. Nitinol waya inoshandiswa zvakanyanya mukurapa, kubhururuka, mota uye mamwe minda nekuda kweiyo yakanakisa chimiro memory alloy (SMA) zvivakwa uye superelasticity.
Pfungwa huru
●Shape memory effect:Chimwe chezvinhu zvinokatyamadza zveNitinol waya chimiro chayo chekurangarira maitiro. Zvinoreva kuti mushure mekuita imwe dhigirii yemagetsi deformation, nekuipisa kune chaiyo tembiricha, iyo alloy inogona kudzokera kune yayo yekutanga preset chimiro pasina kusiya deformation zvachose. Izvi zvinokonzerwa nekushandurwa kwechikamu chekuchinja pakati pemartensite uye austenite zvimiro zveNitinol alloys pane tembiricha dzakasiyana.
●Superelasticity:Kuwedzera kune chimiro chendangariro mhedzisiro, Nitinol waya dzinoratidzawo yakanakisa superelasticity. Iyo alloy inochengeta elasticity kunyangwe iri pasi pemamiriro akakura ekuchinja uye inogona kukurumidza uye nemazvo kudzokera kuchimiro chayo chepakutanga, ichiita kuti inyanyo batsira mumashandisirwo anoda kazhinji deformation uye yakakwirira elastic zvinodiwa.
● Mamiriro ekristaro anochinja:Izvi zvimiro zveNitinol zvinonyanya kutsamira pane yakaoma crystal chimiro. Pakudziya kwakadzika, iyo alloy iri muchikamu chemartensitic uye ine yakakwirira formability. Kana tembiricha yakwira pamusoro penzvimbo yakakosha, inoshanduka kuita chikamu che austenitic, nokudaro ichidzokera kuchimiro chayo chepakutanga.
Nyaya dzinoda kutarisirwa
●Kudzora tembiricha:Chimiro chekuyeuka mhedzisiro uye superelasticity yealloy zvinoenderana nekushanduka kwekushisa. Naizvozvo, ambient tembiricha inoda kunyatsodzorwa panguva yekushandiswa kuve nechokwadi chekuti alloy inogona kuita basa rayo nemazvo pasi pemamiriro ekushisa anodiwa.
●Hupenyu hwekuneta:Kunyangwe iyo Nitinol waya inoratidza yakanakisa elastic kudzoreredza kugona, inogona kukanganisa hupenyu hwayo hwekuneta nekuda kwekugara kwenguva refu deformation uye yakanyanya-kushushikana mamiriro. Nokudaro, kusimba uye kugadzikana kwenguva refu kwechigadziro kunoda kutariswa mukugadzira uye kushandiswa.
●Processing tekinoroji:Kugadziriswa kweNitinol kwakaoma. Kucheka, welding uye kugadzira maitiro kunoda yakakosha michina uye maitiro. Aya matanho anobatsira kudzivirira kukuvadza iyo alloy's microstructure uye zvivakwa.
Derivative product
●Midziyo yekurapa:Mundima yekurapa, Nitinol waya inoshandiswa zvakanyanya mucardiovascular stents, mazino orthotics, sutures yekuvhiya nemimwe michina. Yavo superelasticity uye chimiro chendangariro mhedzisiro inobvumira izvi zvishandiso kuti zvigadzirise zvirinani kune yemukati nharaunda uye inopa inogara kwenguva refu yekurapa mhedzisiro.
●Aerospace:Muchikamu chemuchadenga, waya yeNitinol inoshandiswa sechinhu chepamusoro-simba, zvinhu zvisingaremi, senge elastic support zvimiro uye aerospace mudziyo zvibatanidza. Aya maapplication anoda kuti zvinhu zvichengetedze kuita kwakagadzikana pasi pemamiriro ekunze akanyanya.
●Consumer electronics:Sezvo tekinoroji ichifambira mberi, waya dzeNitinol dziri kutanga kushandiswa muzvigadzirwa zvemagetsi zvevatengi, senge zvinobhenda zvikirini muma smartphones uye zvinochinjika zvinongedzo mumidziyo inopfeka. Aya maapplication anowedzera kusimba uye mushandisi ruzivo rwechigadzirwa.
●Kugadzirwa kwemaindasitiri:Nitinol waya inoshandiswa zvakanyanya mukugadzira maindasitiri sechikamu cheakangwara zvinhu, senge masensor, actuators uye otomatiki michina. Yayo chimiro chendangariro mhedzisiro inobvumira izvi zvishandiso kuti zvirambe zvine hunyanzvi uye zvakarurama pasi pemamiriro ekushanda akasiyana.
Pakazara, sechinhu chepamberi chekushanda, Nitinol waya haina kungoshandura mamiriro etekinoroji eindasitiri yemazuva ano neminda yekurapa asi yakaunza hunyanzvi uye mikana yekusimudzira maindasitiri akasiyana. Nekunzwisisa kwakadzama kwekuita kwayo uye mashandisirwo, zvinotarisirwa kuti ichave nekuwedzera uye inosvika kure tarisiro yekushandisa mune ramangwana.
