Corrosion Protection Methods

By Prof. Kallol Mondal | IIT Kanpur

Learners enrolled: 936

ABOUT THE COURSE:
The course will focus on different corrosion protection methods, like cathodic and anodic protection, design change, change of environment, inhibitors, and coatings. In addition, it will discuss the effect of metallurgy, processing, microstructure and surface texture on the corrosion protection. This is very important for students and industry personnel. It will also help them to assess the degree of corrosion damage and accordingly select suitable protection route.

INTENDED AUDIENCE:
1. Bachelor and Master students
2. Industry people, where corrosion is a problem
3. PhD student working in corrosion

PREREQUISITES: Chemical Thermodynamics, Phase transformation and Electrochemistry

INDUSTRY SUPPORT: Oil companies, Chemical companies and Power sector, construction, Steel

Course certificate

The course is free to enroll and learn from. But if you want a certificate, you have to register and write the proctored exam conducted by us in person at any of the designated exam centres.

The exam is optional for a fee of Rs 1000/- (Rupees one thousand only).

Date and Time of Exams: April 29, 2023 Morning session 9am to 12 noon; Afternoon Session 2pm to 5pm.

Registration url: Announcements will be made when the registration form is open for registrations.

The online registration form has to be filled and the certification exam fee needs to be paid. More details will be made available when the exam registration form is published. If there are any changes, it will be mentioned then.

Please check the form for more details on the cities where the exams will be held, the conditions you agree to when you fill the form etc.

CRITERIA TO GET A CERTIFICATE

Average assignment score = 25% of average of best 6 assignments out of the total 8 assignments given in the course.
Exam score = 75% of the proctored certification exam score out of 100

Final score = Average assignment score + Exam score

YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100.

Certificate will have your name, photograph and the score in the final exam with the breakup.It will have the logos of NPTEL and IIT Kanpur. It will be e-verifiable at nptel.ac.in/noc.

Only the e-certificate will be made available. Hard copies will not be dispatched.

Once again, thanks for your interest in our online courses and certification. Happy learning.
