Inyungu y'ivyuma bikomeye vy'ivyuma vyera.

Ivyuma bikomeye vy’ivyuma ni icuma cera c’ivyuma birimwo nickel na chromium, akenshi vyitwa Ni-Hard mw’isi. Dushingiye ku vyo chromium birimwo, bishobora guca mu mice ibiri: w (Cr) 2% na w (Cr) 9%.

Mu gikoresho gikomeye cera c’i 2% w (Cr), carbide ni (Fe, Cr) C, gifise uburemere bwa 1100 ~ 1150 HV, hejuru y’uburemere bwa carbide Fe, C (900 ~ 1000 HV). Mu gicurarangisho c’umweru gikomeye ca nickel c’ibice 9% w (Cr, carbide nyinshi ni (Cr, Fe) C3 n’uburemere bwinshi. Ibiharuro 8-6 vyerekana ko hariho n’ukwongerwako Cr ku guhingura carbide.

Ivyo bikoresho vy’ivyuma bikomeye cane mu gitereko c’ivyuma gikomeye ni ugutuma icuma gitera neza, ivyo bikaba bifasha kuronka icuma c’ivyuma. Igitigiri c’ibirimwo nickel bivana n’uburemere bw’uruhome rw’ivyo gutera, kandi nickel ari mu ruhome rw’uruhome rurerure bikwiye gufata umupaka munini.

(1) Igikoko. Ivyuma vyinshi vy’ivyuma vy’umuyagankuba birafise uburemere bwinshi, ubushobozi bwiza bwo kwambara n’itandukaniro ry’imbere, mu gihe carbone iri hasi ari vice versa. Bivanye n’ibikorwa bitandukanye 2) silikoni. Ivyo silikoni iri muri Ni{5}} Hard 1 na Ni - Hard 2; chromium nini ya Ni-Hard 4 iva kuri 1,8%~2.0%. Umuti mwinshi utera imbere mu guhingura (Fe, Cr), C; ubwoko bwa carbide, kandi bugatuma ubushuhe bw’amabere butera imbere M, ivyo bikaba bituma umuntu ashobora kuronka matrix y’amabuye y’agaciro yitwa martesite, ariko ni uguzimya kw’ivyuma vy’amabuye y’agaciro.

(1) Igihimba c’umubiri c’ivyuma bikomeye vy’umukara vy’umukara vy’agaciro vy’agaciro kanini mu Bushinwa (raba Imbonerahamwe 8-2). Ishirahamwe ry’igerageza ry’ibikoresho vyo muri Amerika (ASTM) ryashizwe muri Leta Zunze Ubumwe za Amerika kandi rigabanywamwo ibice bine A, B, C na D (raba Umugereka E2). Mu Bwongereza, Ubudage na bwo nyene bwemeye ingingo ngenderwako y’igihugu. Ishirahamwe Mpuzamakungu ry’Ishirahamwe ry’Ibihugu vy’Abarabu rivuga kandi ivy’imiti y’ivyuma vy’ivyuma vyera bikomeye (raba Imbonerahamwe 8-16).

(3) IKIGANIRO. Chromium itera imbere mu guhingura carbide, kandi igatuma chromium ihurizwa hamwe neza muri Ni -Hard 4 ifise carbone na silikoni, kugira ngo igice kinini c’umubiri w’umuntu (Fe, Cr) C3, gutuma ubushobozi bwo kwambara n’ubukomezi bukomera

(4) Nickel. Nickel ahanini ipfutse mu gikoresho c’ivyuma, ivyo bikaba bishobora gutuma umuntu agira ubushobozi bwo gukora neza no gutuma haba uguhingura matrix canke heutus matrix. Ubushobozi bwa Mi- Umusi wa 4 burarengeye cane ubw’i Ni{-Hard 1, bushobora gutuma umuntu akora n’igice icumi ku 200mm. Nickel itera imbere mu gupima, ni co gituma ubwanaka bw’akanwa k’ubururu bukomeye bw’akanwa gakomeye gafise ikintu kinaka c’ibara ry’agahama kugira ngo ntihagire uguhingura graphite. Nickel irahagarara iyo austenite, kandi ibirimwo nickel vyinshi bituma umuntu agira austenite y’abasigaye.

(5) Inyigisho. Manganese ishobora guhagarika austenite, rero ivyo birimwo manganese ni bike.

(6) Molybdenum. Molybdenum irashobora gutuma umuntu ashobora kubaza neza kandi ashobora gukoreshwa ku bihimba vy’umubiri bikomeye iyo bikenewe.

Ishirahamwe ryacu ritanga ubushuhe {{0}=imyambaro idashobora guhinduka - imiyoboro itariho, ishobora guhindura impuzu zo kwambara -iriho bivanye n’ivyo umukiriya akeneye.
