Zinc Alloy Electrodeposition for Corrosion Protection

t is known that the protective value of zinc is partially a result of its ability to form a protective film when plated on a base metal, such as steel. The zinc is sacrificial and corrodes I preferentially to protectthe steel. Although pure zinc coating provides some degree of protection for the substrate, in a severe corrosion environment, zinc is consumed rapidly. For this reason, it is usual...

Zinc-Alloy-Plating for Corrosion Protection

Zinc represents the most effective and economic corrosion protection especially for steel base materials. Improved corrosion resistance can be achieved by alloying zinc with small amounts (around 1 Yo) of transition metal elements like Co, Ni and Fe. Zn-Fe and Zn-Co alloys containing up to 1.5 Yo of the transition metal were plated using an alkaline and acidic electrolyte respectively. Zn-Ni al...

A review of galvanic anode cathodic protection design procedure

Electrochemistry is a physical science. As a general definition physical sciences apply mathematical equations, making some assumptions in order to predict/explain phenomena/mechanism occurring in the natural environment. The mechanism of cathodic protection in seawater has been covered exhaustively elsewhere and the intent of this paper is to focus on the procedure of the galvanic (sacrificial...
