Lecture 8 : Surface Properties of Materials
 



Surface Mechanical Property: Wear due to Corrosion

Wear due to Corrosion is quantified the same way as the mechanical wear.
The list provided below gives a qualitative idea to the Designer to choose a metallic alloy under prevalent environmental conditions.

Aerated Water:

High resistance – Lead Alloy, Steel Alloy, Titanium Alloy, Nickel Alloy, Copper Alloy

Medium resistance – Aluminium Alloy

Low resistance: Carbon steels

Strong Acids:


High resistance – Lead Alloy, Titanium alloy, Stainless Steel
Medium – Aluminium Alloy

Strong Alkali:


High resistance – Nickel Alloys, Steels, Titanium Aloy
Medium – Copper Alloys, Zinc Alloys
UV: all alloys
