When the concentration electrolysis test pvd machine remains unchanged, the coating machine changes the current density, the temperature of the electrolyte, and the smooth (hard) chromium can obtain three different lattice layers, namely, gray face, bright and milky white chromium layer

1) The gray chrome layer is obtained at low temperature, and the chrome layer of the coater is obtained at high current density. From a high degree (HV=uoo), the method of toughness, a mesh pattern, strong color, dark crystal. Use measuring tools and chrome plating.
2) The bright chromium layer is the chromium layer obtained at the medium temperature, and the coating machine has low current density. High hardness (HV=800), good toughness, wear resistance, low internal stress, dense grid lines, fine grains, and bright surface. It is applicable to repair of worn parts.
3) The milky white chromium layer is the chromium layer obtained at a higher temperature. The plastic coating machine (HV=400 - 500) with low current density and low hardness of the coating machine has good plasticity, no net wrinkles, fine grains, and white appearance. It is suitable for increasing the size of parts under impact load and plating decorative chromium.
Porous chrome plating machine and dotted chrome layer and chrome layer groove can be used by electrochemical and mechanical methods. The performance of porous chrome plating to adsorb lubricating oil. Therefore, it has better wear resistance.
When the chrome-plated parts on the cathode of the predetermined line are chrome-plated, this will lead to the anode. The chrome plating machine will electrolyze the personality's acid solution (electrolytic discharge). Through DC, the surface of the chrome layer will be coated with a thin and uniform layer!
