B-85 Hardfacing Welding Electrode inyanzviTsvimbo Inobata MazisoYakagadzirirwa kuisa nzvimbo dzisingapfeki zvakanyanya pamidziyo inokwenywa zvakanyanya, kukweshana, uye kukuvara kuri pakati nepakati. Ichi chitanda chekuwedera che arc chinogadzira madziro ekudzivirira anochengetedza kunaka munzvimbo dzinopisa zvakanyanya uye dzinopisa. Yakanakira kuvakazve nekudzivirira michina yeindasitiri, iyi Hardfacing Rod inowedzera hupenyu hwebasa mumamiriro ezvinhu akaomarara ekushanda.
Iyo electrode'Nzira yakasiyana yekugadzirwa kwe chromium flux inoita kuti simbi yakachengetwa igadzire chimiro chakasimba uye chakasimba. Hunhu uhwu hwesimbi hunodzivirira zvikuru kubva pakuboorwa, kupwanywa, uye kukuvadzwa kunokonzerwa nemaminerari, matombo, uye matope anokwesha. Kufukidza uku kunodzivirira zvinobudirira zvinhu zvepasi kubva mukuora, kunyangwe kana zvikasangana nekupisa kunosvika 600°C (1112)°F) kana mhepo inoparadza inowanzo kuwanikwa mumigodhi, simende, uye kushandiswa kwezvinhu.
Chinokosha pakushanda kwayo hunhu hwakanaka hwemakanika hunopiwa neB-85Tsvimbo Inobata MazisoKana ikashandiswa muzvikamu zviviri sezvinokurudzirwa, weld deposit inosvika pakuoma kwe57–62 HRc (Rockwell C scale). Kuomarara uku kwakanyanya pamusoro kunodzivirira kurasikirwa kwezvinhu kubva mukutsvedza kwekukweshana uye kukuya zvine simba, kunyangwe nzvimbo yacho isingafanirwe kukuvadzwa zvakanyanya kana kupwanywa zvakanyanya nekuda kwekuoma kwayo kwepanyika padanho iri rekuomarara.
Tsvimbo iyi inobudirira muzvinhu zvakaita sema "crusher hammers", ma "augers", mazino e "trencher", ma "pulverizer rollers", uye ma "chute liner". Kugadzikana kwayo pakupisa kwakanyanya kunoita kuti ive yakakodzera zvikamu zve "furnace" uye zvikamu zve "kiln". Vashandisi vanofanirwa kucherechedza zvipingamupinyi zvayo pakushanda: kunyangwe ichidzivirira kukwenywa uye kudzvanywa zvine mwero, "overlay" haina kusimba pakushandiswa kunosanganisira "hammer" inorema, "point impacts" dzakanyanya, kana "stroke" dzakakombama. Kupisa kwakakodzera kwe "pre-heat" uye "controlled interpass" kwakakosha kudzivirira kutsemuka.
Kune maindasitiri ari kurwisa kushandiswa kwemidziyo inodhura, B-85Tsvimbo Inobata Mazisoinopa mhinduro yekudzivirira isingadhuri. Musanganiswa wayo wekuoma kwakanyanya (57–62 HRc), kugadzikana kwekupisa kwakanyanya/kuora, uye kuramba kukweshana kwakawedzerwa chromium kunoita kuti iyi Hardfacing Rod ive yakakosha pakuvakazve michina yakakosha. Kana ikashandiswa nemazvo mukati memiganhu yayo yekukanganisa, inoderedza zvakanyanya nguva yekushanda uye mari yekutsiva mumigodhi, simbi, uye zvikamu zvekugadzirisa zvinhu zvinorema.
