In 1905, from a large number of experimental results, people summarized an overpotential that was manifested by the electrochemical polarization of hydrogen. (usually expressed in absolute values) and the empirical formula for current density, ie:   l ai | α + blgi Where: α, b are constant, V. It can be seen from the formula C 8 - 16 ) that l a | is linear with lgi, such as See Figure 8-10. When H+ is reduced on various metal electrodes, the overpotential difference is large. For example, the overpotential for the reduction of H+ at the lead electrode is almost 2. 5 times that of the electrode. This illustration fully illustrates the effect of electrode materials on electrochemical polarization. For electrodes reacted with gaseous substances  Said that this effect is quite outstanding. The effect of the electrode material on the hydrogen overpotential is mainly represented by the constant G of (8-16). When the hydrogen is precipitated on different metals, the α value changes greatly. The αJ values ​​of various electrode materials are listed in Table 8 - 1    The composition of the solution is different, and the electrochemical polarization of the H+ reduction reaction is also different. In strong alkali solution, the concentration of H+ ion is very small. Discharge is difficult. At this time, the reaction on the electrode is not H+ but water molecules, ie: H20 + e = OH - + H11 H suction + H, and H2 The electrochemical polarization of H + when reduced on certain metals (such as uranium) is very small. At this time, the concentration polarization of the electrode is often quite large and cannot be ignored. Moreover, in the presence of concentration polarization, the relationship between overpotential and current density can not be applied in equation (8-16). 5. Electrocrystallization of Metals The process of reduction of metal ions or their complex ions to the metal at the cathode is called metal electrodeposition. Because the metal coating deposited on the cathode during electroplating is actually a metal crystal, that is, a metal reduction reaction occurs on the cathode, and the deposited metal is crystallized.  Form growth and growth, this is called electrocrystallization of metals. Electro-crystallization is somewhat different from the general nexus because it is a chemical reaction that involves electrons. Diamond Hole Saw Set. As already mentioned, at the equilibrium potential, the rate of Ni2 + reduction reaction is equal to the rate of metal oxidation protection reaction, so the metal town variety cannot be formed: only under the conditions of cathode polarization,  Can produce metal dry seeds. The overpotential in the electrical junction product is equivalent to the effect of the supersaturation of the solution in the general crystallization process, and the higher the overpotential, the easier the formation of the metal species, and thus the formation of crystals of small particles in the plating. In general, when the metal grain is small and  When the orientation is tight, the resulting coating quality is better. Therefore, in the electroplating industry, it is often tried to increase the overpotential of the cathode reduction reaction so as to increase the speed of the variety formation, thereby obtaining smooth and dense metal crystals. Increasing the current density and adding an organic surface active material to the plating solution can generally increase the overpotential at which the metal precipitates on the cathode. If the temperature rises, the overpotential can be reduced and larger grains may be formed. However, the adverse effect of increasing the temperature can be achieved by increasing the current density.  To make up for it, high temperatures are sometimes used in electroplating production.       When many simple metal ions are reduced at the cathode, the electrochemical polarization is very small, mainly concentrated polarization. For example, the electrocrystallization of Ag, Cu, Cd, Zn, etc. is the same, and when the iron element is electrocrystallized from a simple metal ion solution, the electrochemical polarization is quite large. The vast majority  The metal complex ions, such as Cu (CN), Zn (CN), etc., are also electrochemically polarized at the cathode to form a metal product.
