Chitsulo chonyamula zinthu cholimba ndi gulu lapadera la aloyi lomwe limapangidwira kuphatikiza mphamvu zonyamula katundu komanso zosatha za zitsulo zachikhalidwe zonyamula zinthu komanso kukana kwambiri okosijeni ndi zinthu zowononga. Pamene mafakitale akukankhira zida m'malo ovuta.—mphamvu za m'nyanja, kukonza chakudya, zamankhwala, mankhwala, ndi mphamvu zongowonjezwdwanso—Ma bearing a chromium okhala ndi mpweya wambiri (monga SAE 52100) sali okwanira. Zitsulo zoteteza dzimbiri zimawonjezera nthawi yogwira ntchito, zimachepetsa nthawi yogwira ntchito komanso kukonza, ndipo zimathandiza kuti ntchito ikhale yodalirika pamene pali chinyezi, mchere, ma acid kapena zinthu zotsukira. Chidule cha malondachi chikufotokoza mitundu yayikulu ya zitsulo zoteteza dzimbiri, kupita patsogolo kwaposachedwa, ndi zabwino zomwe zimapangitsa kuti zikhale chisankho chabwino kwambiri pakugwiritsa ntchito zinthu zovuta.
Mitundu ya zitsulo zoteteza dzimbiri zimagawidwa m'magulu angapo, iliyonse yokonzedwa bwino kuti ikhale yolimba, yolimba komanso yolimba. Zitsulo zosapanga dzimbiri za Martensitic (monga AISI 440C ndi zina zofanana ndi X46Cr13) zimagwiritsidwa ntchito kwambiri pamene pakufunika kuuma kwambiri ndi kukana dzimbiri; zimatha kutenthedwa kuti zitheke kutopa kwambiri. Zitsulo zosapanga dzimbiri zomwe zimalimbitsa mvula (17-4PH, 15-5PH) zimapereka mphamvu zambiri, kulimba komanso kukana dzimbiri pambuyo pouma, zoyenera kugwiritsa ntchito ndege ndi ma bearing a mafakitale. Zitsulo zosapanga dzimbiri za Austenitic (monga 316L, 304) zimapereka kukana dzimbiri bwino kwambiri ndipo zimagwiritsidwa ntchito pamene dzimbiri limagwira ntchito bwino kwambiri, ngakhale kuti nthawi zambiri zimakhala ndi kuuma kochepa komwe kungatheke. Ma alloy omwe akutuluka omwe ali ndi nayitrogeni wambiri komanso apadera (Cronidur 30 ndi zitsulo zina zolimbitsa nayitrogeni) amapereka kutopa bwino komanso kukana dzimbiri. Zitsulo zosapanga dzimbiri za powder metallurgy (PM) zimapereka ukhondo wabwino kwambiri, kuwongolera kapangidwe kake komanso kufanana kwa ntchito zofunika kwambiri.
Kukula kwa zitsulo zoteteza dzimbiri kwawonjezeka chifukwa cha kapangidwe ka alloy, kusungunuka ndi kukonza zinthu zatsopano, komanso ukadaulo waukadaulo wa pamwamba.Kusungunuka kwa vacuum induction melting (VIM) kwamakono, kusungunuka kwa electroslag (ESR) ndi ufa kumachepetsa kuphatikizika ndi kuwonjezera ukhondo, zomwe zimapangitsa kuti moyo wa kutopa ukhale wabwino. Kuphatikizika kwa nayitrogeni wambiri komanso chromium, molybdenum ndi nickel zikhale bwino zimathandiza kuti mafilimu amphamvu asamagwire ntchito komanso kuti pakhale kukana bwino kutayikira kwa maenje. Kuchiza ndi kutentha ndi kukonza cryogenic kumakonza ma microstructure a martensitic kuti akhale olimba komanso okhazikika. Kumbali ya pamwamba, kusungunuka kwa plasma kotsika kutentha, zokutira za PVD/DLC, ndi ma ceramic kapena ma polymer liners owonda amatha kuwonjezera kukana kutayikira popanda kuwononga chitetezo cha dzimbiri. Kapangidwe ka alloy yowerengera ndi kuyesedwa kwachangu kwa kutopa ndi kutopa kwa ntchito zatsopano.
Ubwino ndi makhalidwe a ntchito za zitsulo zoteteza dzimbiri zimasanduka phindu lenileni pa zipangizo ndi machitidwe. Zipangizozi zimachepetsa chiopsezo cha kuphulika kwa haidrojeni ndi kugwera m'malo amchere kapena okhala ndi mankhwala amphamvu, pomwe zimasunga mphamvu yolumikizana ndi kukana kuwonongeka komwe kumafunikira pazinthu zozungulira ndi kuthamanga. Kusakonza pang'ono komanso mafuta ochepa kapena kusintha nthawi zambiri kumachepetsa ndalama zomwe zimagwiritsidwa ntchito pa moyo wonse.—Chofunika kwambiri pa malo osungiramo zinthu, kukonza chakudya, ndi malo ochitira zamankhwala. Magiredi ambiri amagwirizana ndi miyezo yaukhondo (monga FDA/USP) akamalizidwa bwino, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito mwaukhondo. Kuphatikiza apo, kupezeka kwa zinthu zotenthetsera, zomaliza bwino komanso zida za PM zomwe zimakhala ndi mawonekedwe ofanana ndi neti zimathandiza opanga kukonza mabearing kuti azilemera, phokoso, komanso magwiridwe antchito bwino pamene akufupikitsa nthawi yopangira zinthu.
Mwachidule, zitsulo zonyamula zitsulo zosagwira dzimbiri zimaphatikiza luso la zitsulo ndi kukonza kwamakono kuti zipereke maberiya odalirika komanso okhalitsa omwe amagwira ntchito pomwe zitsulo zachikhalidwe sizikugwira ntchito. Ubwino wawo waukulu—kukana dzimbiri, kuuma kosalekeza komanso mphamvu yotopa, kuchepetsa kukonza, komanso kugwiritsidwa ntchito m'malo olamulidwa bwino komanso ovuta—Apange kukhala chisankho chosangalatsa kwa mainjiniya ndi akatswiri ogula omwe akufuna kudalirika komanso kuchepetsa mtengo wonse wa umwini. Sankhani njira zathu zothetsera dzimbiri zomwe sizingawonongeke kuti musankhe zinthu mwaluso, kupanga zinthu molondola, komanso kusintha momwe zinthu zilili.
