Must be because I'm using a white bath but look at this, you can actually see the rust travelling to the rod. This by the way is what’s happened in the time it's taken to eat my dinner check all the icky stuff gathering at the bottom ohh that looks nasty

I've inhanced the contrast so you can make out the tiny bubbles which started streaming from it the instant I switched the charger on, I like this Rescued attachment cleaning.jpg

Where did you say that housing development you walk your dog past is, could do with a bath to clean some bits in

What I meant was, what type of soda? Washing, baking, brand etc and to what concentrate did you mix it?

Thanks,
Steve


Mr Whippy - 18/3/08 at 08:30 AM

Its just washing soda, I forget the make. Concentration was err that will do... I think it was suppose to be 1 table spoon per gallon but I just poured it in all over the part. I wish I had time this morning to take a pic at just how dreadful the water looks now left it running today so expect a very clean part when I get home

I found some more bits of flat bar, 4 in total and that really speeded things up. I'm quite impressed with this, so easy and effective, now I can rescue all the steel wheels I have for trailers lying about

I might build this into the new garage and put some real thought into getting it running perfect, like a 24v supply and maybe a mesh grid on the bottom instead of the bars.

Remember lads.... DONT use anything with Stainless Steel or Chrome in it for the sacrificial plate.

Whilst it might last a bit longer, the chemical reaction gives off Hexavalent Chromium

Please see:

Just a timely reminder for those who have not read the whole story, or been on here long enough to have heard about it.

Remember It pays to be safer rather than sorrier.

.........and while I DO use stainless and have conveniently ignored the hexavalent chromates, I ought to point out again that there is another, very small and almost certainly insignificant, failing of the process.


On explaining it to a metallurgist in our heat treatment department at my last company, he was amazed, but then pointed out the issue of hydrogen embrittlement.

This is where hydrogen produced at the surface being treated, is actually absorbed (and ADsorbed) by the surface of the steel, and if then highly stressed, can cause cracking.

The good news is:

1) any embrittlement is unlikely to cause issue at the stress levels encountered on our diy stuff

and

2) it can be got rid of by a stint in an oven, and decreases with time after treatment as the hydrogen gradually exits the steel crystal structure.

all in all, don't worry, but DON'T for goodness sake treat a leaf spring or something as it WILL snap!!

try the springs on your battery charger clamps if they get in the solution for any length of time and you'll see what I mean!!!!
