Platinised titanium manufactured by a special process in which the titanium substrate is modified prior to plating. This process confers almost total freedom from interface degradation and premature loss by undermining.
The titanium surface is modified to improve adhesion of platinum and to significantly improve uniformity of coating thickness. A further benefit is reduction in coating porosity imparting greater acid resistance to the anode.
The manufacturing route includes application by thermal decomposition of noble metals followed by electroplating to produce a dense wear-resistant layer of platinum. A variety of shapes and forms are available including bar, rod, sheet and mesh. Individually fabricated anodes are available to suit customers’ special requirements.
Platinised titanium is used extensively in cathodic protection particularly for sea water intake structures and heat exchangers where its resistance to abrasion is superior to most other anode coatings.
The advantages using platinised titanium are
+ High levels of adhesion of the precious metal coating
+ Improved resistance to acid attack
+ Resistance to interface degradation by deposits
+ Significantly longer life
Practical consumption rates for cathodic protection applications over a wide range of current densities are uniform and proportional to the current passed. However, individual conditions of operation can significantly influence wear rate. Under normal oceanic conditions, excluding low temperatures, wear rates correspond to 1 and 2 micrograms of platinum per ampere hour.
