Chapter 20, Problem 48A

Interpretation Introduction

Interpretation:

How a galvanization iron is to be protected.

Concept introduction:

Galvanization is the process in which a coat of zinc is applied to thicker base metal surface which are prone to corrosion such as iron.

Answer to Problem 48A

Galvanization is the process in which a coat of zinc is applied to thicker base metal surface which are prone to corrosion such as iron. Hot dipping is the most common method of galvanization. It involves a final stage of dipping of steel into a bath of molten zinc at high temperature such as $\text{460}$ degree Celsius. The zinc bonds with the steel and forming the zinc steel alloy coating, which forms zinc oxide on the surface. This zinc oxide layer helps protect the steel increase its life spam.
