Strip electrolus nickel

It can blend with a cyanide of sodium, can blend with the nickel exfoliation on iron, and sulfuric acid, and can carry out nickel exfoliation on copper and brass. A peel rate is quick and many amounts of metal dissolutions are economical. Moreover, liquid is stable and it is hard to disassemble it, and also since a toxic substance is not included, liquid waste treatment is easy. Moreover, it is hard to carry out stable decomposition of the dipping, and also since a toxic substance is not contained, liquid waste treatment is easy. The stability of liquid is good and a peel rate does not hurt its foundation quickly, toxic substances, such as cyanogen, are not included.

Residual macrostresses in electroless nickel EN coatings affect critical deposit properties such as hardness and adhesion. Straight thin aluminum, beryllium, and steel strips were plated in hot nickel hypophosphite baths varying in chemistry, pH, and usage. When the nickel-phosphorus Ni-P coating was stripped from one side the metal strip assumed either a concave tensile or a convex compressive arch because of internal stress in the EN coating. The degree of curvature was measured and the residual stress calculated.

I am trying to remove electroless Nickel coating and Copper strike from steel without corroding the steel surface. So far my results are very inconsistent: parts cleaned in the same acid vat never look the same. What am I missing in this process?
