Desribe An Electrochemical Test Procedure

[mark555550]

Describe an electrochemical test procedure that could be used to assess an organic coating. [You will need to look back at earlier learning packages and possibly do some extra research to answer this question fully]. Explain how the test is conducted, the parameters used and what you are actually measuring. How does this relate to your understanding of the corrosion protection and degradation mechanisms of organic coatings used on metal substrates?

So you want us to do your homework for you.

And not so much as a please or thank you.

You are destined to be one of life's failures.

The answer is 18 microns of zinc, 10 volts / 1800 amps for 20 minutes.

Yup you have to look at your learning packages especially the ones that deal with teaching oneself


think about polarography

You dunk your coated thingey in an electrolye and put a pd across it and measure the current w r t time

[sunny-dave]

"You dunk your coated thingey" ... I'm not even sure that's legal in this country PP ...

[tonyav]

That would depend on whether it's a coated thingy of many colours or not, Dave.

[Peter Pedant]

so long as it is organically coated then you can suck it and see !

actually i think you vary the voltage and see what the current is
as some ions need a sort of oomph before they start being deposited

honestly the fella needs to read his books ....

[woofgang]

also a please and thank you wouldn't come amiss.

LOL.
