Hi friends
i have an issue of black shade on the surface ADC12 DIECAST PARTS after chromating Alodine 1200.
The diecasted parts also have black shade because of high silicon content .
The diecasted are machined and glass bead blasted before chromating.
We have been observing that black shades remain after chromating.
Can anyone post your views in this regard?
