The water is ,scaling, because as pH increases, total alkalinity concentration increases. This is due to an increase in the carbonate ion, which bonds with calcium ions present in solution to form calcium carbonate (reference the carbonic ,acid, equilibrium, in which hydrogen ions bond with carbonate ions to form bicarbonate and hydrogen ions bond with bicarbonate to form carbonic ,acid,).

Anodizing - Wikipedia

Anodizing, is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts.. The process is called ,anodizing, because the part to be treated forms the anode electrode of an electrolytic cell.,Anodizing, increases resistance to corrosion and wear, and provides better adhesion for paint primers and glues than bare metal does.
