I-Plasma Yakha i-Welding Corrosion Resistant Alloys

I-PlasmaYakha iWelding, njengenye yetekhnoloji yokomeleza umphezulu, ineengenelo zokujonga izinto ezahlukeneyo zomgubo wealloyi, umaleko oshinyeneyo wokujonga phezulu, idilution ephantsi, ukusebenza kakuhle kwemveliso, ukusetyenziswa okuphantsi kwemathiriyeli yealloyi, kunye nexabiso eliphantsi.Umphezulu wayo awugugi, awugugi, ukuphuculwa kokumelana nobushushu obuphezulu kuye kwatsala ingqalelo engakumbi.

Okwangoku, i-iron-based, i-nickel-based kunye ne-cobalt-based alloy powders isetyenziswa kakhulu kwiplasma.i-buildup welding.I-iron-based alloy powder inokumelana nokunxiba kakuhle kunye nexabiso eliphantsi, kodwa ukuxhathisa ubushushu kunye nokuxhathisa ukubola.I-nickel-based kunye ne-cobalt-based alloy powders inokumelana ne-corrosion kunye nokusebenza okuphezulu kobushushu, kodwa ixabiso liphezulu kakhulu.Ukusebenzisa i-plasma arc ukufaka i-iron-based self-fluxing alloy powder, i-nickel-based self-fluxing alloy powder kunye ne-nickel-based alloy kunye ne-wc composite powder kumphezulu we-16mn yentsimbi, ngokusebenzisa iimvavanyo zokunxiba kwimidiya eyahlukeneyo eyonakalisayo, iziphumo ezintathu. iintlobo zomaleko obuphezulu zaphononongwa iMicrostructure, ukubunjwa kwesigaba, ubulukhuni kunye nokumelana nokunxiba.

Impembelelo yemithombo yeendaba eyonakalisayo ekuxhathiseni ukunxiba kwe-alloy surfacing layer ikwahlukile.Ukumelana nokunxitywa komgangatho ophezu komhlaba kwindawo engathathi hlangothi enamanzi ingcono kunaleyo ye-acidic kunye ne-alkaline medium.Oku kungenxa yokuba isinxibo esinye sisebenza emanzini.Kwisisombululo se-HCl se-dilute kunye ne-dilute ye-NaOH isisombululo, i-micro-battery yenziwa phakathi kwe-compound kunye nesisombululo esiqinileyo, kwaye kukho ukusebenzisana phakathi kokugqoka kunye ne-electrochemical corrosion, ukwenzela ukuba i-surfacing layer in the dilute HCl solution.Kwaye ukuxhathisa ukunxiba kwi-dilute ye-NaOH isisombululo esiphakathi kuncitshisiwe ngenxa yempembelelo yokumelana nokubola.

Ukuthelekisa ukunyanzeliswa komgangatho wokugubungela kwi-HCl kunye nokuhlambulula i-NaOH medium, kufunyaniswa ukuba ukuxhathisa ukunxiba kwi-dilute ye-HCl medium kubi, kuba umaleko ongaphezulu unokwenza ifilimu yokudlula kwi-HCl kwaye udibanise i-NaOH medium, Nangona kunjalo, ifilimu ye-passivation kwi-HCl ye-dilute kulula ukuwohloka, kwaye ifilimu ye-passivation kwi-dilute ye-NaOH medium ayonakaliswa lula, ngoko ke ukunyanzeliswa komgangatho we-surfacing layer kwi-dilute ye-NaOH medium ingcono kune-dilute HCl acid..

Ubunzima bomaleko we-Ni60 obuphezulu bufana nobo be-Fe55.Ukumelana nokunxiba kwe-Ni60 engaphezulu kwisisombululo se-hydrochloric acid kunye ne-dilute ye-NaOH isisombululo singcono kune-Fe55, kodwa okuchaseneyo kuyinyaniso emanzini angathathi hlangothi.Kumaleko angaphezulu kwe-alloy efanayo, ukuxhathisa kokunxiba kwindawo engcolisayo yesisombululo se-HCl se-dilute kunye ne-dilute ye-NaOH isisombululo sisezantsi kunoko kumanzi angathathi hlangothi, kwaye ukuncipha kubonakala ngakumbi kumbindi womhlaba oneasidi.
