If you want to know what proportion of hard chrome plating additives to be added, you must first understand the composition ratio and scope of application of various hard chrome plating additives, experienced plating masters can judge the proportion of various additives, but the hard chrome process itself is a knowledge. If you lack experience in this area, you can also choose a good potion supplier to help you solve.
Using Bigely hard chrome plating additives Cr-2 as an example, the following steps are to be observed when formulating the plating solution:
1. Clean the plating tank, then have the worker add two-thirds of the volume of water, followed by heating the plating solution to 45℃.
2. Add chromic anhydride at the ratio of 250g/L and mix well.
3. Add chemically pure sulfuric acid at the ratio of 2.5g/L. Note that the sulfuric acid content in chromic anhydride should be deducted here. Mix well.
4. Add 20ml/L of hard chrome additive CR-2, add water to the required volume and mix well.
5. Place a lead-tin containing anode (tin content of 7-10%), with a pseudo-cathode with an area five times the area of the anode, and electrolyze for 4 hours (Dk controlled at 15A/dm2)
6. Heat up the plating solution to 55℃ and start plating.
