Ni ikihe kigoye

Hardfacing ni ugushyiramo umubyimba mwinshi wibikoresho bikomeye, bidashobora kwihanganira kwambara hejuru yambarwa cyangwa ibintu bishya bigomba kwambaramu gusudira, gutera amashyuza, cyangwa inzira isa. Gutera amashyuza, gutera-fuse hamwe no gusudira muri rusange bikoreshwa mugukoresha urwego rukomeye. Ibikoresho bisanzwe bikoreshwa birimo cobalt ishingiye kuri alloys (nka tungsten karbide), nikel ishingiye kuri nikel,chromium karbideibishishwa, n'ibindi. Hardfacing rimwe na rimwe ikurikirwa no gushyirwaho kashe kugirango tunonosore igice cyangwa wongereho ibara cyangwa amakuru yerekana igice. Amafirime cyangwa firime birashobora gukoreshwa muburyo bwo kureba cyangwa ubundi burinzi

Gutera amashyuza bikundwa kubisabwa bisaba kugoreka ubushyuhe buke bwibintu no kugenzura neza. Ibikoresho bisanzwe bigoye kubikwa no gutera amashyuza harimo cermets nka WC-Co hamwe nubutaka bushingiye kuri alumina. Iyi myenda ikoreshwa mubugari bwa 0.3mm.

Imyenda ya spray-fuse nayo yiswe kwifata hejuru yikintu, ibanza gukoreshwa hejuru yikintu ukoresheje uburyo bwo gutera flame hanyuma igahuzwa hanyuma ukoresheje itara rya oxyacetylene cyangwa coil ya induction ya RF. Ipitingi yahujwe ihanagura hejuru yubutaka kugirango ikore igifuniko gihujwe nicyuma kandi kidafite ubukana. Hariho ubwoko butandukanye buvanze bukoreshwa hamwe na spray-fuse, icyingenzi gishingiye kuri sisitemu ya Ni-Cr-B-Si-C. Ukurikije ibihimbano bishonga murwego rwa 980 kugeza 1200 ° C. 

Weld ikomeye ireba ikoreshwa mukubika umubyimba mwinshi (1 kugeza 10mm) ibice byuzuye byibikoresho bidashobora kwambara hamwe nimbaraga zikomeye. Uburyo butandukanye bwo gusudira burashobora gukoreshwa, harimo gaze ya inert (MIG), tungsten inertgaze (TIG), plasma yimuwe arc (PTA), arc yarengewe (SAW), nicyuma cyamaboko arc (MMA). Ubwinshi bwagutse bwibikoresho bishobora gukoreshwa. Harimo ibishishwa bishingiye kuri cobalt (tungsten karbide nibindi), martensitike nicyuma cyihuta cyane, nikel alloys na WC-Co ciment ya karbide. Nyuma yo kubitsa muburyo ubwo aribwo bwose bwo gusudira hejuru, akenshi birakenewe kurangiza ubuso bwibice.

Hardfacing irashobora kubikwa muburyo butandukanye bwo gusudira:

·Icyuma gikingiwe arc gusudira

·Gusudira ibyuma bya arc gusudira, harimo byombi bikingira gaze hamwe no gusudira arc

·Oxyfuel gusudira

·Kurohamaarc welding

·Gusudira amashanyarazi

·Plasma yimuwe arc gusudira, nanone bita powder plasma welding

·Gutera ubushyuhe

·Ubukonje bwa polymer

·Kwambika Laser

·Ikomeye
