  Times, using the open circuit potential measurement. Impedance measurements with the chart shows, shown in Figure 3. In Figure 3, the impedance of the specimen 3 the highest,uggs nederland, followed by sample 6,uggs outlet, sample 4 and 5 was slightly lower than the impedance of the specimen 6, and the two curves almost coincide, the impedance of the specimen a condition for the six electrical parameters the next lowest. Obviously,franklin marshall, after micro-arc oxidation treatment were higher than the impedance of the sample anodized and untreated sample impedance. From the above analysis shows that conditions on the electrical parameters of the ceramic layer is not determined by a single factor, but by the frequency, number of pulses and duty cycle and other factors determined, therefore, only through the interaction of various factors with the ceramic layer in order to make up a good performance. 4 Conclusion (1) obtained in the high-frequency ceramic layer than the low frequency density significantly increased. (2) at high frequencies, the greater the duty cycle,abercrombie españa, the ceramic layer surface roughness C: Cancer 3 different electrical parameters of the sample under the conditions of micro-arc oxidation electrochemical impedance spectra 1 to 6. Micro-arc oxidation samples, corresponding to the electrical parameter setting method in the 1-6 treatment,billiga uggs, 15 ~ 18m; 7. Anodized sample, 15btm; 8. Degree of untreated samples, the more rough; duty cycle smaller, the smaller the surface roughness of the ceramic layer, the more smooth. (3) magnesium alloy micro-arc oxidation ceramic coatings by electrochemical impedance frequency, pulse number, duty cycle and other factors. References i '[1] Zhu Zufang.
