Inkcazo: I-W707 yi-electrode yentsimbi enobushushu obuphantsi ene-hydrogen sodium coating ephantsi. Sebenzisa i-DCEP (i-electrode yangoku ngqo) kwaye ingadityaniswa kuzo zonke iindawo. Isinyithi esifakwe kwi-depositi sisenokuqina okuhle kwi--70°C.

Isicelo: Isetyenziselwa ukuwelda intsimbi enobushushu obuphantsi efana ne-2.5Ni.
