Description

You will be introduced to the fundamentals of the Pilling-Bedworth ratio and oxidation mechanisms where the corrosion rate of the active-passive metal decreases largely due to galvanic coupling with a noble metal. This course will teach you about the anodic protection of active-passive metal, which is economically beneficial due to lesser current flow in the circuit at the same degree of protection. The relative corrosion response of a metal in an electrolyte, as well as its corrosion resistance, will also be covered.

This free course then explains the gaseous oxidation of metals in the presence of oxygen, as well as how metals react with gaseous oxygen to form metal oxide. You will learn about the different factors for a metal oxide to be protective, as well as calculating the Pilling-Bedworth ratio for different metals. Analyze aspects of oxidation like the thermodynamics of oxide formation and kinetic analysis of oxide growth, as well as learning to plot Ellingham diagrams. Isothermal and non-isothermal experiments are also part of the material.

Furthermore, you will get familiar with how an oxidation process occurs in metal-deficient diffusion of interstitial cation. You will learn about the difference between the oxygen mechanism in two N-type situations such as metal ion interstitial cation and oxygen-vacant sites. This free online course will be of great use to budding metallurgists and anyone with an specific interest in oxidation mechanisms. So, register for this course now and start your next learning journey today.
