Thanks for this informative video. What will be impact of initial delay time wrt to end results?
@metallovers82265 жыл бұрын
you have to wait until open circuit potential reaches a steady state before PD tests in order to produce reproducible results.
@mohanparamasivam39515 жыл бұрын
Thanks for your reply. But my actual doubt is : Say we are keeping 5 mins initial delay and 1hr initial delay, will the results be accurate in both cases. If Yes / No - Why it is So?

based on the number of repeated tests that one performs, average, standard deviation, range etc. of measured data can be calculated.

Thank you for the video, this will definitely help me with my project , may i please ask, if you have 4 samples to test, after each test, do i have to redo the cleaning, i will be using the same electrolyte sample and different metal samples. Also , the counter electrode, does it need to be changed?
@metallovers82265 жыл бұрын
The test itself may change pH of the electrolyte, it is better to repeat the cleaning and use new electrolyte every time.

Load is not representative of a load on a real screw. A good way to cause loading might be to screw it into something that will result in many lbs of force on the screw rather than just a tiny weight. I would suggest a machine screw, and put it through say a plastic tube with nut on the end and tighten it up. Make sure the solution can easily get into the tube. I would also suggest stirring.

So how much is the at-home kit?
@metallovers82266 жыл бұрын
This process requires a glovebox which typically costs over 20K. If performed at home, one may use ionic liquid that is not sensitive to air and water, that way glovebox is not required. The costs of high quality ionic liquid electrolyte can be a few hundred $ per 100 ml.

The electrochemical part is the same, but the sample prep and container will be quite different.

The screw in a group got only 1/5 of the reacting element compared to the unloaded screw. Next time consider loading the screw with a nonreactive load, like rubber.
