电镀过程中的相关设备和基本术语（Related equipment and basic terminology in electroplating process）

电镀过程中的相关设备和基本术语（Related equipment and basic terminology in electroplating process） Related equipment and basic terminology in electroplating process 1. dispersing capacity: under certain conditions, the plating solution can make the coating on the plating surface more evenly distributed. Also known as plating capacity. 2. covering power: the ability of a bath to deposit metals in grooves or deep holes under certain conditions. Also called deep plating ability. 3. leveling capacity: plating solution to make the outline of the coating more smooth than the bottom. Micro dispersion capability. 4. current density: the intensity of current passed on an electrode per unit area, usually expressed as A/dm2. 5. current efficiency: the quality of the actual precipitation (or dissolution) of a substance in electrolysis, and the ratio of the mass to which the theoretical calculation should be precipitated (or dissolved). 6. cathode coating: electrode potential of the generation of value than the big metal matrix metal coating. 7. anode coating: electrode potential value of algebraic metal coating than the base metal small. 8. anode slime: the dissolution of the anode after the action of the current. 9. deposition rate: metal thickness is deposited on the surface of parts in unit time. 10. initial current distribution: the distribution of current on the electrode surface when the electrode polarization is not present. 11. activation: the passivation of metal surface. 12. passivation: in a certain environment, the metal surface dissolved normally, the reaction is seriously hindered, and within a wide range of electrode potential, the dissolution rate of metal is reduced to a very low role. 13. hydrogen embrittlement: brittleness caused by the absorption of hydrogen atoms by metals or alloys due to erosion, degreasing, or electroplating. 14. a material that deposits metal or forms a coating on it. 15. auxiliary cathode: in order to eliminate the burr and charred parts plated on pow
