How to measure the plating metals of single layer

Example: The measurement of the zinc plating with white passivation on the steel substrate , it’s thickness is 10μm.

1. Use the rubber to wipe away the passivation films on the surface of zinc plating of the article to be measured.
2. Depress the testing head vertically on the surface of the article to be measured, applied adequate pressure until without any leakage.
3. Electrolytic solution A8 is selected from table 2 for the combination of zinc plating on steel substrate. The cell must be filled with 2 ml of the electrolytic solution by using a dropper. The cell will not be filled full. (The solution level is about 3 mm from the opening of the cell)
4. Insert pipette to the bottom of the electrolysis cell, repeat suck several times in order to remove the air bubble from cell, enables the electrolytic solution to contact completely with the zinc plating, before placing the stirrer to given position.
5. Depress the Zn button.
6. Insert the signal plug into the hole of the screw of the electrode, attach the red signal clip to the plated object and be sure that a proper connection has been done.
7. press the measurement button, the stirrer begin rotating, while the buzzer alarms, the measurement will be stopped automatically, the thickness 10 μm has been displayed on the indicator, press the stop button.
8. Press the print button to get the list of the measurement results. (if you don’t need the list you can skip this step)
9. Raise the stirrer, clean up the used electrolytic solution by using the pipette, rise the testing head, remove the article.
10. Clean up the internal surface of the cell and gasket by rinse water and wiping. Be sure that there is not any oxidation products on them before they are replaced back.

How to measure the hard chromium plating

Example: The measurement of the hard chromium plating on steel substrate , the thickness of the hard chromium plating is 35μm.

1. Use the rubber wipe away the passivation films on the surface of chromium plating of the article to be measured.
2. Depress the testing head vertically on the surface of the article to be measured, applied an adequate pressure until without any leakage.
3. Electrolytic solution A2 is selected from table2, the cell must be filled with 2 ml of the electrolytic solution by using a dropper. The cell will not be filled full. (The solution level is about 3 mm from the opening of the cell)
4. Insert the pipette into the bottom of the electrolysis cell. Repeat suck several times, in order to remove the air bubble from the cell, enables the electrolytic solution to contact completely with the chromium plating.

Note: When measuring the chromium plating placing the stirrer is not a requirement.

5. Depress the plating of Cr select button and the Cr measurement button. (the plating of Cr select button: --- measure the decorate chromium --- measure the hard chromium)
6. Insert the signal plug into the hole of the screw of the electrode, attach the red signal clip to the plated object and be sure that a proper connection has been done.
7. press the measurement button, the stirrer begin rotating, when the thickness of 15μm shows on the indicator press the stop button then press the print button(if not the tester could not work normally), renew the electrolytic solution, again press the measurement button. Renewal of the electrolytic solution should be made at frequency of even 15μm until buzzing. Record the thickness of the hard chromium plating.
8. Clean up the used electrolytic solution by using the pipette. Rise the testing head. Remove the article.
9. Clean up the internal surface of the cell and gasket by rinse water and wiping. Be sure that there is not any oxidation pro ducts on them before they are replaced back.

How to measure the multi-layer plating

Example: The measurement of the thickness of the multi-layer deposits consisting of copper,nickel and chromium plating on the steel substrate . The thickness of the component layers is 0.4μm of chromium, 14μm of nickel, 10μm of copper.

1. Use the rubber wipe away the passivation films on the surface of plating on the article to be measured

TG-100D and TG-100E
① TG-100D and TG-100E are traditional economical instruments. TG-100G uses computer resources to form a virtual instrument through corresponding software, which is more powerful.
② TG-100E is an improved type of TG-100D, equipped with a miniature printer, which can automatically print plating species, thickness and test time.
③ The surface of the NdFeB product is microporous. During the electrodeposition process, nickel deposits penetrate into the pores of the matrix to form a layer of inconspicuous interface, so there is no potential mutation characteristic of conventional interfaces. Conventional thickness measuring instruments Unable to determine the measurement end point correctly. Using the TG-100G electrolytic thickness gauge, the simultaneous measurement of thickness and potential can effectively solve the problem of measuring the coating of neodymium iron boron permanent magnets.
④ Multi-layer nickel coating measurement uses TG-100G electrolytic thickness gauge, which can analyze the thickness and potential difference of each layer of nickel through the curve.

The difference between TG-100D and TG-100E is: TG-100D has no printing function, no clock display, other properties are the same.
