Of the reactive metals, only commercially pure zirconium This paper will explore the results of testing intended to determine the best surface conditioning methods for the use of zirconium in hydrochloric acid environments. Scales are deposits caused by the deposition of calcium carbonate on the inner surface of the water treatment equipment pipes or tanks. (Remember opposites attract and likes repel and in chemical reactions oxygen tends to have a negative charge and thus seeks to combine with positively charged particles whether metallic or otherwise) CounterAct slows this reaction This inversion of the double layer serves to greatly reduce the rate of oxygen transport to the metal surface and thus also greatly reduce the rate of corrosion as evidenced by our history of rigorous laboratory and field tests. The chemical characteristics, such as alkalinity, hardness and pH of the water flowing through a pipe will influence corrosive reaction. Corrosion (Short Note) Definition Corrosion is the deterioration of a metal, as a result of its reactions with the environment or any chemical agent. Corrosion is the destruction of metals and alloys by the chemical reaction with the environment. It is an oxidation process that occurs at the surface of the metal. Several environmental factors affect the corrosion rates and the composition of the corrosion products, such as metal type, chemical composition of the bulk water, electrochemistry, and microorganisms (Borenstein 1994). The rust layers formed on most conventional structural steels detach from the metal surface after a critical time, and the corrosion cycle commences again. Corrosion and scale are both intricate and complex processes that are influenced by several factors – water characteristics, metals used and any stray electrical current – to name a few. Although few metals can survive chemical environments with high concentrations of chloride ions; reactive metals such as tantalum, niobium, zirconium, and titanium can offer superior corrosion resistance.

The greatest strength of EonCoat compared to all polymers is corrosion protection.
