Ibyuma

Ibisobanuro by'ibyuma bitagira umwanda

Mu kirere cyangwa imiti ishobora kwangirika irashobora kwangirika kwangirika kwicyuma kinini, ibyuma bitagira umuyonga nubuso bwiza kandi birwanya ruswa, ntibigomba gushyirwaho isahani hamwe nubundi buryo bwo kuvura, kandi bigakinisha imiterere yihariye yibyuma, bikoreshwa muri ibintu byinshi byubwoko bwibyuma, mubisanzwe byitwa ibyuma bidafite ingese.Mw'izina ry'imikorere ya chromium 13, 18- chromium - nikel ibyuma nibindi byuma binini cyane.
Duhereye ku byuma bya metallografiya, kubera ko ibyuma bitagira umwanda birimo chromium hamwe nubuso bwo gukora firime ya chromium yoroheje cyane, firime yatandukanijwe na ogisijeni mubyuma byibasiye ruswa.Kugirango ugumane ruswa irwanya ibyuma bitagira umwanda, ibyuma bigomba kuba bifite chromium irenga 12%.

Amateka yiterambere ryibyuma

Impamvu ibikoresho byuma nicyuma bikoreshwa cyane ni ukubera kwibumbira mu bucukuzi bw'amabuye y'agaciro, ububiko bunini, ubucukuzi bw'amabuye y'agaciro ndetse no gushonga, hamwe n'ubukonje bukabije n'ubushyuhe bukabije bw'icyuma kirangiye.Ibicuruzwa byarangiye bifite imiterere yubukanishi (imbaraga, plastike hamwe ningaruka zo guhangana) hamwe nuburyo bwo gutunganya (gukata, gusudira, guhindura imbeho, nibindi).Ariko ugereranije nibikoresho bya acide silicic, ibikoresho bya sintetike ya polymer hamwe nibyuma bimwe na bimwe bidafite ferrous, imbogamizi nini ni: mukirere cyangwa aside, alkali, umunyu nibindi bitangazamakuru, byoroshye guta ibiro kubera ruswa, ndetse no kurimbuka burundu.

Ubwoko bwibyuma

Ibyuma bitagira umwanda birashobora gushyirwa mubikorwa ukoresheje, imiterere yimiti nuburyo bwa metallografiya.
Ibyuma bya austenitis bigizwe na 18% chromium -8% nikel, kandi ingano ya buri kintu iratandukanye, kugirango itezimbere ubwoko butandukanye bwibyuma.
Gutondekanya kubigize imiti: seriesCr ikurikirana: urukurikirane rwa ferrite, urukurikirane rwa sisitemu ya Martensite seriesCr-Ni: Urutonde rwa sisitemu ya Austenite, urukurikirane rudasanzwe, urukurikirane rwimvura.
Itondekanya ryimiterere yicyuma: (1) ibyuma bya austenitike,
