Ibyuma bidafite ibyuma :
Ibyuma bidafite ibyuma ni ubwoko bwibikoresho, bifite hafi yindorerwamo yindorerwamo, gukoraho cyane nubukonje, nibyibikoresho byinshi byo gushushanya avant-garde, bifite imbaraga zo kurwanya ruswa, kubumba, guhuza no gukomera nibindi biranga urukurikirane, bikoreshwa mubikorwa bikomeye , inganda zoroheje, inganda zo murugo no gushushanya inyubako nizindi nganda.
Ibyuma bidashobora kwangirika byitwa ibyuma bitagira umwanda, bigizwe nicyuma kitagira umwanda hamwe nicyuma cyihanganira aside ibice bibiri, muri make, birashobora kurwanya kwangirika kwikirere kwicyuma cyitwa ibyuma bitagira umwanda, kandi birashobora kurwanya ruswa yangirika yibyuma byitwa aside irwanya aside. Muri rusange. nukuvuga, chromium yibiri muri Cr irenze 12% yicyuma ifite ibiranga ibyuma bidafite ingese。
Ibyuma bidafite ibyuma classification
Hariho uburyo bwinshi bwo gutondekanya ibyuma bitagira umwanda, muribyo bikunze kugaragara ni ubu bukurikira.
Imiterere y'ibyuma:
Irashobora kugabanywamo ibyuma bya austenitis, ibyuma bya ferrite, ibyuma bya martensitike, ibyuma bitagira ibyuma, duplex idafite ibyuma, imvura ikomera ibyuma bitagira umwanda.
Ibigize imiti:
Ahanini birashobora kugabanywamo ibyuma bya chromium bidafite ingese (nka ferrite ikurikirana, sisitemu ya martensite) hamwe na chromium nikel ibyuma bitagira umwanda (nka sisitemu ya austenite, urukurikirane rudasanzwe, imvura ikomera) sisitemu ebyiri.
Ukurikije ubwoko bwo kurwanya ruswa:
Irashobora kugabanywamo imbaraga zo kwangirika kwangirika kwangirika kwicyuma, guhuza ibyuma bitangirika kwangirika, kwangirika kwangirika kwangirika kwicyuma, nibindi.
Bishyizwe mubikorwa bikora:
Irashobora kugabanwa kubusa gukata ibyuma bitagira umuyonga, ibyuma bidafite magnetiki ibyuma, ubushyuhe buke butagira ibyuma, imbaraga nyinshi zidafite ibyuma.
Hariho ubwoko 100 bwibyuma bitagira umwanda byashyizwe mubipimo bitandukanye kwisi, kandi hamwe niterambere rya siyanse nikoranabuhanga hamwe niterambere ryinganda n’ubuhinzi, amanota mashya y’icyuma na yo ariyongera.Ku cyiciro kizwi cy’icyuma kitagira umwanda , chromium ihwanye na [Cr] na nikel ihwanye na [Ni] irashobora kubarwa ukurikije ibiyigize, kandi microstructure hamwe nimiterere yibyuma birashobora kugereranywa ukoresheje imbonerahamwe ya microstructure ya Schaeffler-Delong idafite ibyuma.
Ibyiciro bya Matrix :
1.
2. Ibyuma bya Austenitike bitagira umuyonga.Birimo chromium irenga 18%, nikel hafi 8% hamwe na molybdenum, titanium, azote nibindi bintu.Imikorere myiza yuzuye, kurwanya ruswa kubitangazamakuru bitandukanye.
3. Austenite-ferrite duplex ibyuma bitagira umuyonga.Bifite ibyiza bya austenite na ferrite ibyuma bitagira umwanda, kandi bifite superplasticity.
Martensitike idafite ibyuma.Imbaraga ndende, ariko plastike mbi no gusudira.
Imeza yicyuma isanzwe igereranya imbonerahamwe hamwe nimbonerahamwe
