Mixed Metal Oxide Activated Titanium Anode For Impressed Current Cathodic Protection
² The mixed metal oxides are formed on the substrate through a process of thermal- decomposition, creating an oxide coating of the platinum group metals. The oxide coatings have many the superior performances, such as
ü Lightweight
ü MMO coatings demonstrate very high chemical stability even in environments with very low PH values.
ü The coating is not affected by the generation of chlorine.
² The wear rate of the anode is extremely low and uniform and between 1 and 6 milligrams/ampere-year.
² The anode dimensions remain nearly constant during the design life .
² Operated at high current density, 2000A/m2.
² The superior electrically-conductive performance: 10-7Ω·m
Substrate
Ti ,Ta ,Nb ,Zr ,Ti/Cu, Nb/Cu etc.can be used as substrates. But Of all substrates Ti and its clad is generally used. The titanium substrates are commercially pure titanium
