I know in this video I want to show you how to plate aluminium onto aluminium
and we use here this is a piece test piece of aluminium you use NPU course to
clean it first of all wrap it in like like you use MPU and
rinse it under water like you see here and then put it straight into the sink
Kate right in this case we put it in for 2 minutes to get a sink paint on there
you can't sink on there every 30 seconds or so shake it a little bit moving a
little bit around in the beaker 20-30 seconds here for a little bit when the 2
minutes are over take it out and then you have three beakers for rinsing which
we put on purpose that tell you can't afford any contamination you can use the
first two beakers normal tap water but the last must be dr nice board so it's
very very important so you take it all you can see the colour on when you
change to sink colour rinse it rinse it very well and then the third one this
one is the analyzed water set the rectifier in this case to 0.3 of an amp
so ignore the voltage anyway that makes sure everything is on so now the next
stage it's very important that you put the item in very quickly yeah make sure
it's going and going it quickly rectifier everything is on this is
copper strike solution so you can see the tips Tara there you don't need to
heat it up is room temperature is fine if it's 20 23 degrees Celsius that's
fine so you leave it in there for about five
minutes yeah in this case for about five minutes at room
temperature you can see it must there must be movement so you need a
sterile or hot plates Tara if you can heat it up 25 degrees is fine right yeah
rinse it very well it's important it's rinse very well now we can take your
time a little bit no it's not that important that you need to do it quickly
anyway you put this now in the electro forming copper which is also which is an
acid copper for about 15 minutes then how you set the rectifier you find it on
a spa blending website how to set everything did you know and yeah leave
it in there for 15 minutes in this case it will plate about 10 microns on there
which is enough you can plop right more but 10 microns is fine how do I know
it's 10 microns in 15 minutes roughly well we put it on an x-ray machine we
have mics right here XRF machine and we can measure the thickness anywhere so
when it's done after 15 minutes in this case take it
out yeah after 15 minutes take it all now he can rinse it if you want under
top order or you can go through the beakers again it doesn't matter so no
it's done you can now polish it if you want with a buffing wheel you can now
then you can brush plate if you want come nickel on nail and gold if you want
- brush plating oh yeah and tongue plate whatever you want now this stage is done
now we go to the final test which is very important for us the plate of
aluminium is extremely difficult well it is easy but difficult because
the adhesion is is always a problem now we test the adhesion a simple way very
simple I put tape on the good sticky tape not cheap on rip it off you
can see nothing is coming off so duct tape
yes tape you can see no couple on there no nothing that's it so any questions
please contact me here are the details or leave a comment thumbs up subscribe
if you haven't already put the bail on thanks for watching I've got all my
details on them and see you next time for more videos like this goodbye
