Cobalt 6
ECoCr-A maelectrodes anoratidzirwa neiyo hypoeutectic chimiro, ine network inosvika gumi netatu muzana eutectic chromium carbides yakagoverwa mucobalt-chromium-tungsten yakasimba mhinduro matrix.Mhedzisiro yacho chinhu chine musanganiswa wekupokana kwese kune yakaderera kushushikana abrasive kupfeka, neiyo inodiwa kuomarara kuramba imwe nhanho yekukanganisa.Cobalt alloys zvakare yakanakira kurwisa simbi-kusvika-simbi kupfeka, kunyanya munzvimbo dzakaremerwa dzinowanzoita galling.Iyo yakakwira-alloy yemukati yematrix inopawo kupikisa kwakanakisa kucorrosion, oxidation, uye yakakwira tembiricha yekuchengeta kwekuoma kunopisa kusvika pakukwira kwe1200 ° F (650 ° C).Aya ma alloys haasi pasi pekushandurwa kweallotropic uye saka haarasikirwe neayo zvivakwa kana base simbi inozobatwa kupisa.
Colbalt #6 inokurudzirwa kune zviitiko apo kupfeka kunoperekedzwa netembiricha yakakwira uye uko corrosion inobatanidzwa, kana zvese zviri zviviri.Mamwe maapplications emotokari uye emvura inoyerera mavharuvhu, cheni saw madhairekitori, zvinopisa zvibhakera, shear blades, uye extruder screws.

Cobalt 12
ECoCr-B maelectrodes netsvimbo zvakafanana mukuumbwa kune madhipoziti akaitwa pachishandiswa ECoCr-A (Cobalt 6) maelectrodes nemarodhi, kunze kwechikamu chepamusoro zvishoma (chinenge 16%) checarbides.Iyo alloy zvakare ine yakakwira zvishoma kuoma uye zvirinani abrasive uye simbi-kusvika-simbi kupfeka kuramba.Impact uye corrosion resistance inodzikiswa zvishoma.Deposits inogona kugadzirwa ne carbide maturusi.
ECoCr-B (Cobalt 12) electrodes inoshandiswa zvakasiyana neECoCr-A (Cobalt 6) electrodes.Sarudzo inotsamira pane chaiyo application.
AWS A5.13 ECOCR-C:
Cobalt 1
ECoCr-C ine chikamu chepamusoro (chinenge 19%) checarbides pane madhipoziti akaitwa pachishandiswa ECoCr-A (Cobalt 6) kana ECoCr-B (Cobalt 12).Muchokwadi, kuumbwa, kwakadai zvekuti yekutanga hypereutectic carbides inowanikwa mune microstructure.Chimiro ichi chinopa iyo alloy yakakwirira kupfeka kuramba inoperekedzwa nekudzikisira mukukanganisa uye kushora kuramba.Kuomarara kwepamusoro kunorevawo kuti tsika yakakura inogona kudzikiswa nekunyatso tarisisa preheating, tembiricha yepakati, uye nzira dzekupisa.
Nepo iyo cobalt-chromium deposits inopfava pane yakakwira tembiricha, ivo vanowanzoonekwa senge vasina kutsamwa.ECoCr-C maelectrodes anoshandiswa kugadzira-up zvinhu senge masanganisi, rotor kana chero kupi kwakashata abrasion uye kushomeka kunowanikwa.

Cobalt 21
ECoCr-E maelectrodes ane simba rakanaka kwazvo uye ductility mutembiricha inosvika 1600°F (871°C).Deposits inoshingirira kuvhunduka kwekupisa, oxidizing, uye kuderedza mamiriro ekunze.Kushandiswa kwekutanga kweaya marudzi emaaloyi kwakawanikwa mujet injini zvinhu zvakaita seturbine blades uye vanes.
Iyo dhipoziti ndeye yakasimba mhinduro yakatwasanudzwa alloy ine yakaderera uremu-muzana carbide chikamu mune microstructure.Nekudaro, iyo alloy yakaoma kwazvo uye inoshanda yakaoma.Madhipoziti ane akanakisa ega-mated galling kuramba uye zvakare anoshingirira zvakanyanya kune cavitation erosion.
ECoCr-E maelectrodes anoshandiswa uko kupikisa kutyisa kwekupisa kwakakosha.Typical applications;zvakafanana neaya emadhipoziti akaitwa uchishandisa ECoCr-A (Cobalt 6) electrodes;giredhi rolls, inopisa extrusion uye forging inofa, inopisa shear blades, tong bits, valve trim.
