There are two basic types of chrome plating: hard chrome plating and thin dense chrome plating. Hard chrome plating leaves a layer of chrome from 0.0008 to 0.0050 in. (from 0.020 to 0.127 mm) thick on the surface of the metal.
The electroplating process consists of two main steps: (i) the mass transport of chromium ions through the electrolyte to the surface of the electrode, and (ii) the reduction of chromium ions at the cathode through chemical reactions. c The fundamental equations needed to model the system are: 2.1 Conservation Balances n
Hexavalent chromium plating baths are the most widely used baths to deposit chromium on metal. Hexavalent chromium baths are composed of chromic acid, sulfuric acid, and water. The chromic acid is the source of the hexavalent chromium that reacts and deposits on the metal and is emitted to the atmosphere.
This is a brief review of accepted analytical methods for chromium plating solutions. The relative standard deviation (RSD) of certain methodologies is presented.
Producing high quality chrome plated parts takes diligent attention to detail. Many of the rejects generated with both hexavalent and trivalent chrome processes can be attributed to contamination introduced into the plating tank. We will show you well proven methods to lower reject and rework rates significantly by utilizing filtration

3.1 Influence of bathparameters on the deposition conditions. the plating range of bright and hard chromium deposits depends on the current density and temperature. outside this plating range the chromium deposit is grey, dull and brittle or milky dull and soft.
