Stripping PVD Coatings with H2O2 + NaOH

We use a hydrogen peroxide and sodium hydroxide solution to strip PVD coatings.

I would like to know what the chemical reaction is for this process (I'm looking for the balance equation).

I would also like to know what types of control might be used to test and insure proper make up of the solutions and to test when these solutions are spent.

Thanks,
