Explain metal cladding with labeled diagram.
Method : Metal cladding
Process : i) Base metal is sandwiched or cladded between the two sheets of coating metal.
ii) This sandwich is then passed through two heavy rollers maintained at high temp & pressure.
iii) Cladded metal is cathodic with respect to the base metal so that electrolytic protection is provided metals like Cu, Ni, Ag , Pb, Pt & alloys like stainless steel, Ni alloys, Cu & pb alloys & Pb alloys are used as cladding materials.
