Cobalt 6
ECoCr-A electrode irangwa na hypoeutectic structure, igizwe numuyoboro wa karubide ya chromium igera kuri 13% ikwirakwizwa muri cobalt-chromium-tungsten ikomeye yumuti.Igisubizo nigikoresho hamwe nuruvange rwo kurwanya muri rusange guhangayikishwa no kwambara nabi, hamwe nubukene bukenewe bwo kurwanya ingaruka runaka.Amavuta ya Cobalt nayo ni meza muburyo bwo kurwanya ibyuma-byuma, cyane cyane mubihe biremereye bikunda guhitanwa.Ibintu byinshi bivanze na matrix bitanga kandi imbaraga zo kurwanya ruswa, okiside, hamwe nubushyuhe bwo hejuru bwo kugumana ubushyuhe bugera kuri 1200 ° F (650 ° C).Iyi mavuta ntishobora guhinduka kuri allotropique bityo ntutakaze imitungo yabo niba icyuma fatizo gikurikiranwa nubushyuhe.
Colbalt # 6 irasabwa kubibazo aho kwambara biherekejwe nubushyuhe bwo hejuru kandi aho ruswa irimo, cyangwa byombi.Porogaramu zimwe zisanzwe ni amamodoka n'amazi atembera neza, urunigi rwerekanwe, ibishyushye bishyushye, ibyuma byogosha, hamwe na screw ya extruder.

Cobalt 12
ECoCr-B electrode ninkoni bisa muburyo bwo kubitsa bikozwe hakoreshejwe ECoCr-A (Cobalt 6) electrode ninkoni, usibye ijanisha rito gato (hafi 16%) ya karbide.Amavuta kandi afite ubukana buri hejuru gato kandi birwanya kwangiza no kwangiza ibyuma.Ingaruka no kurwanya ruswa bigabanukaho gato.Kubitsa birashobora gukoreshwa nibikoresho bya karbide.
ECoCr-B (Cobalt 12) electrode ikoreshwa muburyo bumwe na ECoCr-A (Cobalt 6) electrode.Guhitamo bizaterwa na porogaramu yihariye.
AWS A5.13 ECOCR-C:
Cobalt 1
ECoCr-C ifite ijanisha ryinshi (hafi 19%) ya karbide kuruta kubitsa hakoreshejwe ECoCr-A (Cobalt 6) cyangwa ECoCr-B (Cobalt 12).Mubyukuri, ibigize, nuburyo hypereutectic carbide iboneka muri microstructure.Ibi biranga biha imbaraga zo kwihanganira kwambara biherekejwe no kugabanuka kwingaruka no kurwanya ruswa.Ubukomere buri hejuru busobanura kandi ko imyumvire myinshi ishobora kugabanuka mugukurikiranira hafi ubushyuhe, ubushyuhe bwa interpass, hamwe nubuhanga bwa postheating.
Mugihe ububiko bwa cobalt-chromium bworoheje muburyo bwubushyuhe bwo hejuru, mubisanzwe bifatwa nkubudahangarwa bwubushyuhe.ECoCr-C electrode ikoreshwa mukubaka ibintu nka mixer, rotor cyangwa ahantu hose gukomeretsa bikabije n'ingaruka nke bihura nabyo.
AWS A5.13 ECOCR-E:
Cobalt 21
ECoCr-E electrode ifite imbaraga ninziza cyane mubushyuhe bugera kuri 1600 ° F (871 ° C).Kubitsa birwanya ihungabana ryumuriro, okiside, no kugabanya ikirere.Gukoresha hakiri kare ubu bwoko bwa alloys wasangaga mubice bya moteri yindege nka turbine blade na vanes.
Kubitsa nigisubizo gikomeye kigororotse kivanze hamwe nuburemere buke-ijanisha rya karbide mugice cya microstructure.Kubwibyo, ibinyomoro birakomeye kandi bizakora cyane.Kubitsa bifite imbaraga zo kwikuramo ubwinshi kandi birwanya cyane isuri.
ECoCr-E electrode ikoreshwa aho kurwanya ihungabana ryumuriro ari ngombwa.Porogaramu isanzwe;bisa nububiko bwakozwe hakoreshejwe ECoCr-A (Cobalt 6) electrode;kuyobora imizingo, gusohora gushyushye no guhimba bipfa, inkweto zishyushye, tang bits, valve trim.
