Tsananguro: Ni307-7 ielectrode yakagadzirwa nenickel ine hydrogen sodium coating shoma. Shandisa DCEP (electrode yakananga yemagetsi)yakanaka). Inoshanda zvakanaka pakuwedera ine arc combustion yakagadzikana, haina kupfapfaidza, iri nyore kubvisa tsvina,uye weld yakanaka. Simbi yakachengetwa ine hunhu hwakagadzikana hwemakanika uye inodzivirira ngura zvakanaka mumhepo ine oxidizing inopisa zvakanyanya uye ine sarufa.

 

Mashandisirwo: Inoshandiswa mukugadzira michina yenyukireya, sulfuric acid, nitric acid uye hydrogen fluorine, senge nickel 690 alloy, ASTM B166, B167, b168, nezvimwewo, inogona zvakare kushandiswa pakushongedza nickel-chromium iron nesimbi isina ngura uye kugadzira zvidimbu zvinodzivirira ngura pamusoro pesimbi.
