Potentiodynamic Polarization Curve Analysis using EC-Lab Software: with system file and excel file
Переглядів 14 тис.6 років тому
In this tutorial, we have demonstrated how to plot and analyse the Tafel curve using EC-Lab software. Two cases have been discussed: when you have the corrosion data in EC-Lab system file (mpt format), and when you have the corrosion data in an excel file. Calculation of E-corr, I-corr, and corrosion rate has been shown. Instructor: N Surya Prakash Like | Comment | Share | Subscribe EC-Lab Soft...

please how to calculate the corrosion inhibition value from these data
Thanks for your video from Beirut, Lebanon!
Thank you sir. Plz share some more videos on Topas
Thank you so much for this informative video. I would like to ask Is the threshold be calculated separately for each sample? So, the values set at the threshold do not need to be the same in every example, right? Thank you so much.
You ae right. The threshold need not be the same in every sample.
Can you please make a video for distribution relaxation times
I have one doubt , xrd report i have word fomet , the formet not supported in xpert highscore how to fix
.raw or .xrdml format is needed.
In Z view software you select the data file. Please do let me know how you make the data file. I have data in logf, Real and Imaginary in -ve value how do prepare the file, rest things I understood. Thank you
The data file is available from the EIS experiment when we run it in the potentiostat.
Nice video and good explanation. Keep it up
Thanks a lot
Hello there. I need to know why you took the other CPE value as 0.9
It was a trial value.
Thank you for your video. Is it possible to tell how can I get a par file for my Instrument and also to know which kind of lamp am I using? PS: My XRD is also the d8 advance.
It will be available with your XRD operator.
Sir when I uplod the xrd data then it shows file format not supported
file format must be .xrmdl
The file be word format same problem to me
@@anshu6008how to change fomat
@@anshu6008i have word format
.raw or .xrdml format is needed.
how to measure thickness?
Great explanation, sir I need your assistance it's really important. I am currently on my thesis for biological cell, how can we conclude our cell as a circuit as there are lot of different circuits in the literature. I am very confused please help. Thanks.
There are standard behaviours for different circuit elements (i.e., resistor, capacitor, inductor, constant phase element (CPE), etc). We need to see the behaviour of our nyquist impedance plot. from there, we have to deduce a circuit. We need to justify our circuit selection based on the actual electrochemical phenomena taking place in our system. There can be multiple circuit combination which will yield the same plot, but we need to justify what circuit elements we take n our circuit. If a nyquist plot is a perfect semicircle, iwe can conclude that the equivalent circuit has a capacitor and resistor in paralel, and we conclude that the nyquist plot is purely capacitive in nature. However, if our nyquist plot is not a perfect semicircle and is slightly flat, we can say that it is not a purely capacitive circuit, and we will take a CPE instead of a capacitor in our equivaent circuit.

Where I can get potentiodynamic polarization test facility
I got my testing done in a facility at our institute IIT Kharagpur. The facility is available in institutes like IITs and NITs and some other institutes and labs that work on corrosion.
very helpfull, thanks too much
Sir, could you help me, how can I measure 0.0625 sq. mm area on an image by using 0.25 mm scale bar. Thank you
Thank you very much
could you explain how to draw it manually the equivalent circuit? thank you
Sir, how can I measure the 1square mm area of an image surface? Please advice..
It says no candidate fount
Thank you so much sir 💐 for making this so simple for me... You are a great teacher.... ❤
hi is there any way I could contact you guys
Thank you Dr. Kundi
Thank you sooo muchh Sir Ji🙏🙏🙏... Very Good lecture. It's highly helpful to my research work Sir. Once again thank you very much.
Welcome 😀
Impressive! Thank you for the video. Could you please let us know how we can do sequential Rietveld refinement in TOPAS?
Welcome. I dont have idea about sequential rietveld refinement.
Exellent !!!!
Good work Broo
Thanks mate!!
what if we don't know anything about the material, how should we deal with that analyze menu
you should have to know atleast elements.
thanks a lot Sir
Detailed video. Very informative and to the point👍.
Which software was used?
Z-view
sir, i have 2 questions. 1. why you convert image to 8 bit? 2.after measuring length of the particle, i want to write text in the image. i used A symbol and i write length unit. once i write i cant edit. can you help me about this
Thanks for the good work. It's my first time trying these analysis, videos just like yours helps a lot!
Thanks for the tutorial. It is a life and time saver. Kudos 🎉
Thank you. it is useful. how to take experimental and matched x and y values for plotting ?
Save the xpert highscore file in ASCII format. From there you can get they x and y values.
Thank you
You're welcome
Where to done labelling?
I am sorry I couldn't follow your lecture at all. Revise what you doing
Hello. Can you pls give the download link? My university systems have 2006 version which does not link to any database and therefore I am unable to perform the pattern search
Is there any free software for fitting?
I am not aware of any free software.
Thanks for the video
Awesome, thank you so much.

Thanks. What is the area value showing in output when we measure the distance between two particles. Highly appreciated for your help.
how to create data file, i have EIS data in excel file.
Copy the data from excel and paste it in a notepad file. Now save the notepad file in "tab delimited" format.
Thank you very much! Super helpful!
