Rectifier For Anodizing Aluminium 8000A 20V

Rectifier For Anodizing Aluminium 8000A 20V

Anodizing is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts.This recctifier is used for the process.

Product Details

Description:The anodized aluminium layer is grown by passing a direct current through an electrolytic solution, with the aluminium object serving as the anode (the positive electrode). The current releases hydrogen at the cathode (the negative electrode) and oxygen at the surface of the aluminium anode, creating a build-up of aluminium oxide. Alternating current and pulsed current is also possible but rarely used. The voltage required by various solutions may range from 1 to 300 V DC, although most fall in the range of 15 to 21 V. Higher voltages are typically required for thicker coatings formed in sulfuric and organic acid. The anodizing current varies with the area of aluminium being anodized and typically ranges from 30 to 300 A/m2.
