Cobalt 6
I-electrodes ye-ECoCr-A ibonakaliswe ngesakhiwo se-hypoeutectic, equkethe inethiwekhi malunga ne-13% ye-eutectic chromium carbides esasazwa kwi-cobalt-chromium-tungsten isisombululo esiqinileyo se-matrix.Isiphumo sisixhobo esinendibaniselwano yokuchasana ngokubanzi kuxinzelelo oluphantsi lwe-abrasive wear, kunye nobunzima obuyimfuneko bokumelana nenqanaba elithile lempembelelo.I-cobalt alloys nayo ilungile ngokwendalo ukuxhathisa ukunxitywa kwentsimbi ukuya kwintsimbi, ngakumbi kwiimeko ezinomthwalo ophezulu othanda ukugabha.Umxholo we-alloy we-matrix unika ukuxhathisa okugqwesileyo kwi-corrosion, i-oxidation, kunye nokugcinwa kobushushu obuphakamileyo bobunzima obushushu ukuya kuthi ga kwi-1200 ° F (650 ° C).Ezi alloys azikho phantsi kwenguqu ye-allotropic kwaye ngoko azilahlekelwa yimpahla yazo ukuba isiseko sesinyithi siphathwa ngokushushu.
I-Colbalt #6 inconywa kwiimeko apho ukunxiba kukhatshwa ngamaqondo obushushu aphakamileyo kwaye apho kubandakanyeka ukubola, okanye zombini.Ezinye izicelo eziqhelekileyo ziivalvu zemoto kunye ne-fluid flow valves, izikhokelo zeesarha zamakhonkco, iipuntshi ezishushu, iibhleyidi zokucheba, kunye nezikrufu ze-extruder.

Cobalt 12
I-electrodes ye-ECoCr-B kunye neentonga zifana ngokubunjwa kweediphozithi ezenziwe ngokusebenzisa i-ECoCr-A (Cobalt 6) i-electrodes kunye neentonga, ngaphandle kwepesenti ephezulu (malunga ne-16%) ye-carbides.I-alloy ikwanobulukhuni obuphezulu kancinci kwaye i-abrasive engcono kunye nokumelana nokunxiba kwentsimbi ukuya kwintsimbi.Impembelelo kunye nokumelana nomhlwa kuthotywa kancinci.Iidiphozithi zinokutshintshwa ngezixhobo ze-carbide.
I-electrodes ye-ECoCr-B (i-Cobalt 12) isetyenziswe ngokungafaniyo kunye ne-electrodes ye-ECoCr-A (Cobalt 6).Ukhetho luya kuxhomekeka kwisicelo esithile.
I-AWS A5.13 ECOCR-C:
Cobalt 1
I-ECoCr-C inepesenti ephezulu (malunga ne-19%) ye-carbides kuneediphozithi ezenziwe ngokusebenzisa i-ECoCr-A (Cobalt 6) okanye i-ECoCr-B (Cobalt 12).Enyanisweni, ukubunjwa, kukuba i-primary hypereutectic carbides ifumaneka kwi-microstructure.Olu phawu lunika i-alloy ephezulu yokumelana nokunxiba ehamba kunye nokunciphisa impembelelo kunye nokuxhathisa ukubola.Ubunzima obuphezulu bukwathetha ukuba ukuthambekela okukhulu kunokuncitshiswa ngokujongwa ngokusondeleyo kwi-preheating, ubushushu be-interpass, kunye neendlela zokufudumeza emva.
Ngelixa i-cobalt-chromium idiphozithi ithambisa ngandlel' ithile kumaqondo obushushu aphakamileyo, ngokuqhelekileyo ithathwa njengengakhuselekanga ekucaphukeni.Ii-electrodes ze-ECoCr-C zisetyenziselwa ukwakha izinto ezifana nezixube, ii-rotors okanye naphi na apho i-abrasion ebuhlungu kunye nefuthe eliphantsi lidibana khona.
I-AWS A5.13 ECOCR-E:
Cobalt 21
Ii-electrode ze-ECoCr-E zinamandla amahle kakhulu kunye ne-ductility kumaqondo obushushu ukuya kwi-1600 ° F (871 ° C).Iidiphozithi zixhathisa ukothuka kwe-thermal, i-oxidizing, kunye nokunciphisa i-atmospheres.Ukusetyenziswa kwangoko kwezi ntlobo zealloys kwafunyanwa kumacandelo enjini yejethi efana neeblade zei turbine kunye neevanes.
Idiphozithi sisisombululo esiluqilima i-alloy echanekileyo kunye nenqanaba eliphantsi lobunzima-ipesenti ye-carbide kwi-microstructure.Ngenxa yoko, i-alloy inzima kakhulu kwaye iya kusebenza nzima.Iidiphozithi zinokumelana okubalaseleyo kokuzibamba kwegalling kwaye ziyaxhathisa kakhulu kukhukuliseko lwe-cavitation.
I-electrodes ye-ECoCr-E isetyenziswa apho ukuchasana nokutshatyalaliswa kwe-thermal kubalulekile.Usetyenziso oluqhelekileyo;zifana nezo zediphozithi ezenziwe ngokusebenzisa i-ECoCr-A (Cobalt 6) i-electrodes;iiroli zesikhokelo, i-extrusion eshushu kunye ne-forging dies, iibhleyidi zokucheba ezishushu, amasuntswana ozwano, ukutrima kwevalvu.
