Letter To The Editor

摘要

I would like to elaborate on the March 2013 article "Hot-Dip Galvanizing Vs. Zinc Electroplating," (pages 99-100). This article described "the two different process application and quality control aspects of zinc for corrosion control." However, the article does not mention the use of thermal spraying (metalizing) as an application method for zinc coatings. Zinc thermal spray coatings have been utilized since the early 1900s and offer excellent corrosion protection. Thermal spray coatings are designed to provide corrosion protection for more than 20 years. Thermal spraying zinc involves the projection of small molten zinc particles onto a prepared surface where they adhere and form a continuous coating. Upon contact, the particles flatten onto the substrate, freeze and mechanically bond.
