Li anodi huma jintużaw għal hard chrome plating

The traditional anode used for hard chrome plating consists of lead alloys. The solution attacks pure lead anodes, causing excessive amounts of lead-chromate sludge to form.

Lead-tin is a typical alloy. Anodes made of lead antimony are used when the weight and length of the anode pose a problem. Anodes made of tin-lead are more durable and have a better conductivity, filwaqt li anodes made of antimony-lead are stiffer. Antimony-lead anodes will last as long and produce a lot of corrosion products. Tin-lead anodes are recommended for high-fluoride baths.  When bl-użu tank anodi in fluworidu għoli banjijiet huma għandhom mhux be hollow or ribbed, but minflok solid u smooth.

Iron anodi huma xi kultant użati in place of lead alloy anodes, especially when greater rigidity and strength is required. Iron and chromium accumulate in the bath if they are used continuously. It is best to use lead-coated iron anodes whenever possible. For special applications, such as plating very small openings with platinum wire, they can be used. However, the bath will also form chromium.  Anodes għal chrome plating should not contain copper, nickel or stainless steel.

In riċenti snin, l-użu ta' nijobju u titanju anodi, li huma indurati, żdied in hard chrome plating banjijiet li do ma fihomx fluworidu. Huma ħadu sostitwixxew il is-soltu ċomb u ċomb illigat anodi. This anode is magħmul of u jista jiżdied throughput by reducing plating time. Anode geometries remain constant for optimal plating results. It has a long operating life and very low maintenance.

Anodes u katodi huma tipikament iqsar in most plating sitwazzjonijiet. This reduces the amount of excess current flowing to the work on the bottom rack. Each anode's bottom should be 6" or more above the bottom surface of the plating tank. If the part has sharp, narrow recesses such as grooves then reducing the distance between the anode and the part can help increase the thickness of deposit on il qiegħ ta' dawn skanalaturi. Some partijiet, tali bħala dawk ma kapijiet u skanalaturi li għandhom sharp corners, ma jistgħux jkun koperti b'mod uniformi sakemm huma huma miksija jużaw jikkonformaw anodi jew auxiliary anos.
