Abstract

The invention provides an electrochromism solution for a gridiron and an electrochromism method thereof. The solution comprises, by weight parts, 40-50 parts of chromic salt, 20-30 parts of cobalt sulfate, 10-20 parts of sodium sulphate, 15-25 parts of potassium sulfate, 15-30 parts of magnesium sulfate, 5-10 parts of sodium dodecyl sulfate, 5-10 parts of nano-sized aluminum nitride, 1-5 parts of sodium dodecylbenzene sulfonate, 1-5 parts of dibutyltin diacetate, 1-5 parts of complex agent, 1-5 parts of coordination agent, 1-5 parts of conducting salt, 1-5 parts of buffering agent, 1-5 parts of organic additives and 80-100 parts of deionized water. The chromic salt is adopted for the electrochromism solution, and the electrochromism solution is environmentally friendly and favorable for production workers' health, does not contain harmful metals such as lead, cadmium and mercury and is high in plating thickness, hardness and corrosion resistance.

Description

technical field [0001] The invention belongs to the technical field of metal surface treatment, and in particular relates to a chromium electroplating solution for a grill and a chromium electroplating method thereof. Background technique [0002] Chromium is a silver-white metal with a slight bluish tint, its relative atomic mass is 51.99, and its density is 6.98-7.21g / cm 3 , the melting point is 1875-1920 ° C, metal chromium is easily passivated in the air, and a very thin passivation film is formed on the surface, thus showing the properties of noble metals. [0003] The chromium plating layer has a high hardness, and its hardness can vary within a wide range of 400-1200HV according to the composition of the plating solution and the process conditions. The chrome-plated layer has good heat resistance. When heated below 500°C, its gloss and hardness will not change significantly. When the temperature is higher than 500°C, it will start to oxidize and change color, and the...
