Platinized Titanium & Niobium Anode Dimensionally Stable Anode

Platinized Anodes are exclusively used in the Hard Chrome Plating application. Platinised Titanium anodes offer several benefits. There are Long life, dimensionally stable and easily fabricated into any shape, Homogeneous and long-lasting active surface, Energy savings with shaped anodes and small anode/cathode distances, reduced environmental burden and reduced maintenance.

Optimum Physical and Chemical Parameters of Platinized Anode:-

By combining platinum and titanium, dimensional stability is possible. Both metals offer optimal parameters for hard chrome plating. Platinum has a very low specific electrical resistance of just 0.107 Ω×mm2/m. Lead’s value is almost twice as high (0.208 Ω×mm2/m). Titanium’s corrosion resistance is outstanding, however, in the presence of halides, this is reduced. The breakdown voltage for titanium in electrolytes containing chloride, for example, is between 10 and 15 V, depending on the pH value. This is significantly higher with niobium (35 to 50 V) and tantalum (70 to 100 V).

What is Hard Chrome Plating?

Hard chromium plating is produced by electrode position from a solution containing chromic acid and a catalytic anion in proper proportion. This article presents the major uses of hard chromium plating, and focuses on the selection factors, plating solutions, solution and process control, equipment, surface preparation, and crack patterns and other characteristics of hard chromium plating. It offers recommendations for the design and use of plating racks, describes the problems encountered in hard chromium plating, and their corrective procedures.
