While the trivalent chromium plating process is more difficult to control, and the necessary chemicals more expensive than that used for hexavalent chromium, the advantages of this method make it cost-competitive with other methods of finishing. The trivalent process requires less energy than the hexavalent process and can withstand current interruptions, making it more robust. Trivalent ...

This paper aims to describe an approximated method for estimating the costs of electroplating processes, by trying to consider only the most important parameters involved, and simplify their choice. The goal is to set a simple but reliable method which can be used to get an overall idea of costs involved in these processes. Electroplating costs are based on 3 main factors: 1. Material 2. Labor ...

This process is known as passivation, and passivated chromium is even stable against acids. There are basically three isotopes of chromium, which are known as 52Cr, 53Cr, and 54Cr, of which 52 Cr is the most abundant isotope. Chromium reacts with most acids, but does not react with water. At room temperature, it reacts with oxygen to form ...

For large, simple surfaces, HVOF can often be applied more cheaply than chrome plating, but for complex geometries, HVOF processing is considerably more expensive than hard chrome. However, given the fact the HVOF coatings perform better and last longer than chrome, savings often accrue in the long term. In any case, the greater up front cost in applying HVOF has deterred many potential users.
