Kufotokozera:
Co 21, cobalt yopangidwa ndi ndodo yopanda kanthu yomwe imapanga mpweya wochepa, austenitic alloy, yokhala ndi zinthu zabwino kwambiri zowumitsa ntchito, kulimba kwa kutentha kwambiri komanso kusagwira ntchito.Co 21deposits imakhala yokhazikika pakakwera njinga zotentha, zomwe zimawapangitsa kukhala chisankho chabwino pazinthu zotentha zakufa.imagwiritsidwa ntchito pamagulu ndi mipando yowongolera nthunzi ndi madzimadzi.Itha kugwiritsidwa ntchito pazitsulo zonse zowotcherera, kuphatikizapo zitsulo zosapanga dzimbiri.Ndilofanana ndi: Stellite 21, Polystel 21.
APPLICATIONS:
Mavavu a Steam.Hot Shears.Kupanga Imfa.Mapulagi Oboola.Chemical ndi Petrochemical Valves.

Ma electrodes a ECoCr-A amadziwika ndi mawonekedwe a hypoeutectic, opangidwa ndi netiweki pafupifupi 13% eutectic chromium carbides yogawidwa mu cobalt-chromium-tungsten solid solution matrix.Chotsatira chake ndi chinthu chokhala ndi kuphatikiza kosagwirizana konse ndi kutsika kwapang'onopang'ono kwa abrasive kuvala, ndi kulimba koyenera kukana kukhudzidwa kwina.Ma aloyi a cobalt nawonso ndiabwino kukana kuvala kwachitsulo ndi chitsulo, makamaka m'malo olemetsa kwambiri omwe amakonda kuphulika.Zomwe zili mu aloyi wapamwamba kwambiri za matrix zimathandizanso kukana kwa dzimbiri, okosijeni, komanso kusunga kutentha kwa kutentha kwambiri mpaka 1200 ° F (650 ° C).Ma alloys awa sakhala ndi kusintha kwa allotropic motero samataya katundu wawo ngati zitsulo zoyambira zimatenthedwa.
Colbalt #6 imalimbikitsidwa pazochitika zomwe kuvala kumatsagana ndi kutentha kwakukulu komanso komwe kumayambitsa dzimbiri, kapena zonse ziwiri.Ntchito zina zomwe zimagwiritsidwa ntchito ndi magalimoto ndi ma valve otaya madzi, ma chain saw guides, nkhonya zotentha, zometa ubweya, ndi zomangira zakunja.

Maelekitirodi ndi ndodo za ECoCr-B ndizofanana m'mapangidwe a madipoziti opangidwa pogwiritsa ntchito maelekitirodi ndi ndodo za ECoCr-A (Cobalt 6), kupatulapo gawo lokwera pang'ono (pafupifupi 16%) la ma carbides.Aloyiyo imakhalanso ndi kulimba kwapamwamba pang'ono komanso kutsekemera bwino komanso kukana kuvala kwazitsulo ndi zitsulo.Mphamvu ndi kukana dzimbiri zimatsitsidwa pang'ono.Ma depositi amatha kupangidwa ndi zida za carbide.
Ma electrode a ECoCr-B (Cobalt 12) amagwiritsidwa ntchito mosinthana ndi ma elekitirodi a ECoCr-A (Cobalt 6).Kusankha kudzadalira ntchito yeniyeni.

ECoCr-C ili ndi maperesenti apamwamba (pafupifupi 19%) a carbides kuposa madipoziti opangidwa pogwiritsa ntchito ECoCr-A (Cobalt 6) kapena ECoCr-B (Cobalt 12).M'malo mwake, kapangidwe kake, ndikuti ma hypereutectic carbides oyambira amapezeka mu microstructure.Chikhalidwe ichi chimapatsa aloyi apamwamba kukana kuvala limodzi ndi kuchepetsa kukhudzidwa ndi kukana dzimbiri.Kuuma kwapamwamba kumatanthauzanso kuti chizoloŵezi chachikulu chikhoza kuchepetsedwa poyang'anitsitsa kutentha kwa preheat, kutentha kwa interpass, ndi njira zowonongeka.
Ngakhale ma depositi a cobalt-chromium amafewetsa pang'onopang'ono kutentha, nthawi zambiri amaonedwa kuti alibe mphamvu.Ma elekitirodi a ECoCr-C amagwiritsidwa ntchito popanga zinthu monga zosakaniza, zozungulira kapena kulikonse komwe kupwetekedwa mtima komanso kutsika kochepa kumakumana.

Ma elekitirodi a ECoCr-E ali ndi mphamvu zabwino kwambiri komanso ductility pakutentha mpaka 1600°F (871°C).Madipoziti amalimbana ndi kugwedezeka kwamafuta, oxidizing, ndi kuchepetsa mlengalenga.Kugwiritsa ntchito koyambirira kwa mitundu iyi ya aloyi kunapezeka m'zigawo za injini ya jet monga masamba a turbine ndi vanes.
Kusungitsa ndi njira yolimba yowongoka ya aloyi yokhala ndi gawo lotsika kwambiri la carbide mu microstructure.Chifukwa chake, alloy ndi yolimba kwambiri ndipo imagwira ntchito molimbika.Madipoziti ali ndi kukana kwabwino kodziyimira pawokha komanso amalimbana kwambiri ndi kukokoloka kwa cavitation.
Ma electrode a ECoCr-E amagwiritsidwa ntchito pomwe kukana kugwedezeka kwamafuta ndikofunikira.Ntchito zofananira;ofanana ndi ma depositi opangidwa pogwiritsa ntchito ma elekitirodi a ECoCr-A (Cobalt 6);masikono owongolera, ma extrusion otentha ndi ma ferging amafa, zometa zometa zotentha, ziboliboli, kudula ma valve.
