The vacuum coating ion ion coating process has become one of the main PVD coating methods. The process operation is completed through multi -arc ion vacuum coating machines. The equipment has two types: vertical and horizontal type. To confirm the qualifications of the product. Dongguan Huicheng Vacuum Technology Co., Ltd. has experienced more than ten years of experience in the production of vacuum coating machine. Here we will introduce several commonly used ion coating testing methods.

The easiest way is to check the appearance of the appearance. If there is a obvious color difference between the standard color board, you can also use the color difference analyzer to test the color. The B value (yellow, blue) compares these data with standard color data, and within the range is qualified products.
        The friction test can be tested through the eight methods of the eight methods of vegetable friction, steel wire friction, mechanical friction, quenching test, salt fog test, ultra -low temperature test, ultrasound test, and landing test. Caulifu friction with 2.5kg ± 0.5kg rubbing back and forth 20 times on the finished product, one -way time is 1 second, there will be no signs of rubbing, whitening, and falling off on the surface of the qualified product; The friction of 0.01kg is rubbed back and forth 5 times on the finished product. The one -way time is 1 second. The scratch range of the qualified product is 3 to 5mm or more; 800 rpm and rubbing for 3 minutes, the qualified product surface allows 3 minor rubbing marks of less than 5mm; the quenching test is tested at the test temperature of copper: 250 ° C, zinc: 150 ° C, 30 minutes. Signs of bubble, peeling, peeling, and discoloration; salt fog testing at 5%concentration, pH3.2 salt soaked for 24 hours without corrosion, foaming, discoloration, and peeling as qualified products; ultra-low temperature tests are low temperature at -40 ° C at low temperature at -40 ° C low temperature The qualified product is falling off.
        The above is a commonly used ion coating test method. Using these methods can test the bad products that appear during the working process of multi -arc ion vacuum coating machines.
