Hi All,
does anyone have a broken, or unwanted, 4AGZE piston that i could have??
i'm really interested to do some analysis on one to dispel some myths about them, and also get some insight as to what they are really made of.
plan is to:
cut it in half, see what the cross section thicknesses are,
polish and macro etch to see grain size (if it truly is forged, you will see the grains 'flow' around the piston)
dig some trenches with an FIB (focussed ion beam miller) to see the structure and thickness of the ceramic coating,
do some chemical analysis, see what is in the alloy and what ceramic they use for the coating (could do XRD for this too)
do some microhardness testing to see what the hardness is and variation throughout the piston.
just your basic investigation 
so, any takers?? the process would be destructive, so you would only get it back in pieces... but the information could be of benefit to all.
Cya, Stewart
