Ibiranga gusudira ibyuma bya austititique: Guhangayikishwa na plastike no guhangayikishwa mugihe cyo gusudira ni kinini, ariko ibice bikonje cyane biragaragara. Nta karere kamanutse hamwe ningano ziguruka muri Weld, niko imbaraga za kanseri yubururu ari hejuru.
Ibibazo nyamukuru byisumbuye ibyuma bidafite ibyuma: Guhindura amashusho menshi; Bitewe numupaka wacyo nibiranga hamwe nubwenge bumwe bwakarengane (s, p), biroroshye kubyara ibice bishyushye.
Ibibazo bitanu byisumbuye byo gusudira hamwe ningamba zo kuvura zinganda zidasanzwe
01 Imiterere ya cromium ya Chromium igabanya ubushobozi bwurubuga rwo kurwanya ruswa ivanze.
Kugabanuka kw'ibicuruzwa bivanze: Ukurikije imitekerereze ya Chromium, kwanduza kaburimbo ya Chromium no kwibasirwa no gushyuha bishyuha kugeza ku bushyuhe bw'ubushyuhe bwa 450-850 ℃, bikaba bikaba bihamije imipaka ya chromium, bidahagije kugira ngo zinanire imbeba.
.
a. Mugabanye ibikubiye mucyuma fatizo hamwe na Welse, hanyuma wongere ibintu bihamye TI, NB nibindi bintu bijya imbere kugirango ushyire imbere gahunda ya MC kugirango yirinde gushinga CR23C6.
b. Kora urubwize imiterere ibiri yicyiciro cya Austenite na Ferrite nto. Iyo hari umubare munini wa Ferrite muri Weld, ibinyampeke birashobora kunonosorwa, ahantu h'ingano birashobora kwiyongera, kandi imvura ya cromium yimodoka ya chromium kuri buri gice cyumupaka w'ingano gishobora kugabanuka.
Chromium irashonga cyane muri Ferrite. CR23C6 ikorwa neza muri Ferrite idatera imipaka ya ausatentange ihingwa muri chromium; Ferrite ikwirakwira hagati ya austenite irashobora gukumira ruswa kumupaka wibinyampeke imbere ya diffusion.
c. Kugenzura igihe cyo guturamo ubushyuhe bwurugero. Hindura uruziga rusukura, gabanya igihe cyo gutura 600 ~ 1000 ℃ bishoboka, hitamo ubushyuhe bworoshye bwo gutangaza, hanyuma ukoreshe ibishushanyo mbonera byongera ubukonje, hanyuma ukoreshe ibishushanyo mbonera byongera ubukonje, hanyuma ukoreshe ibishushanyo mbonera byongera ubukonje, hanyuma ukoreshe uruhara ruto rwo gusunika cyangwa ngo ukoreshe uruhara rworoshye kandi rwo kwirinda gushyushya kenshi, kandi Ubuso bwa contact hamwe na ruswa mugihe cyo gusudira nyinshi bigomba gusudira igihe gishoboka.
d. Nyuma yo gusudira, gukora umuti wakemurwa cyangwa gukomera (850 ~ 900 ℃) no gukonjesha ikirere kugirango usohoke kandi wihutishe diffusion ya chromium).
(2) imyanda imeze nk'icyuma cyo gusudira. Kubera iyo mpamvu, ingamba zikurikira zo gukumira zishobora gufatwa:
Bitewe nubushobozi bukomeye bwo guhagarika karubone, bizatandukanya imipaka y'ibinyampeke kugirango ikore leta yagereranijwe mugihe cyo gukonjesha, mugihe Ti na NB biguma muri kristu yo gukanda. Iyo urusaku rwongeye gushyuha mubushyuhe bwo gukangurira ubushyuhe, karubone yagereranijwe izacibwa muburyo bwa CR23C6 hagati ya kristu.
a. Gabanya ibikubiyemo bya karubone. Kubyuma bitagira ingano birimo ibintu bihamye, ibirimo bya karubone ntibigomba kurenga 0.06%.
b. Koresha inzira nziza. Hitamo ubushyuhe buto bwo gusudira kugirango ugabanye igihe cyo guturamo akarere kegereye ubushyuhe bwinshi, kandi witondere kwirinda ingaruka za 'Gukangurira Ubushyuhe Hagati ' mugihe cyo gusudira.
Iyo gusudira kabiri, gusudira mu rwego rwo hagati byangiza bikaba bisuye nyuma (Iyi niyo mpamvu yo gusudira imbere imiyoboro nini-irasumba hejuru yisumbuye). Niba bidashobora gushyirwa mubikorwa, uburyo buhebuje kandi bugaragaza uburyo buhebuje bugomba guhinduka, kandi tukagerageza kwirinda ahantu heza hahuye na ruswa yongeye gukangurirwa no gushyuha.
c. Kuvura ahavugwa. Kora igisubizo cyangwa kuvura neza nyuma yo gusudira.
02 guhangayika guswera
Ingamba zikurikira zirashobora gukoreshwa mu gukumira ibintu byabayeho kumera:
a. Hitamo neza ibikoresho kandi uhindure ushyira mu gaciro. Icyuma-nickel-nikel austitic ibyuma, nickel ya chicon Umunyabwoba n'umuryango.
b. Kuraho cyangwa kugabanya imihangayiko isigaye. Irashobora gukoreshwa mugutanga isuku-yo kuvura imiti igabanya ubushyuhe, nkiyi Ikirere cyo Kurinda kumurongo-umurongo wimurika ryubushyuhe butera itanura yemeza ihame ryo kwishyurwa. Itanura ryiza rya Ikoranabuhanga rya Hangao (Seko Machinery) ntabwo risaba guteganya, bisaba gusa amasegonda 15 gusa kugirango ugere vuba ubushyuhe bwiza. Muri icyo gihe, ifite ubukana buhebuje, bushobora kubuza neza umwuka usubira inyuma mugihe cyo guhanura. Umuyoboro ushushanyije usutswe ufite imiterere yicyuma kandi imihangayiko ivanze iba nto. Mubyongeyeho, uburyo bwa manikari nko gusya, kurasa no kwirata no kuzungura birashobora kandi kugabanya imihangayiko isigaye.
c. Igishushanyo gifatika. Kwirinda imihangayiko minini.
