After the plasma surface treatment effect test how to identify:
Although we know that the surface properties of materials will change after plasma surface treatment, but the naked eye can not tell whether the material has been treated or not. So, is there a simple way to quickly tell whether the material has been treated or not? The following are some commonly used rapid identification methods.

CRF plasma surface treatment
The user of the plasma surface treatment device can tell at a glance whether the plasma treatment has been performed by displaying the label and observing the plasma indicator compound. It takes almost no time to complete the tests. Can be used in a variety of plasma equipment for a variety of processing purposes, including cleaning, activation, etching or coating. Over the course of weeks or months, these indicators will determine whether your product or semi-finished product has been identified before plasma treatment.


1. Identification label
The pasted label film is a film treated with special coating. It can be placed directly in the box as a reference or pasted on the components. When the dark indicator point disappears, the plasma treatment is completed successfully. Device testing may also use an indication label, in which case the label may be placed in a vacuum chamber.


2, ADP- plasma indicator
The plasma indicator is a label made of a special fabric. After successful plasma treatment, the fabric will dissolve. Attach this sticker to the component or model as needed. It can be used as a reference exposure for plasma jets, and the indicator has no effect on the actual plasma processing process or the device itself. Fabric can be damaged during processing.


3. Plasma indicator -- metal compound
A plasma indicator is a liquid metallic compound that decomposes in a plasma to give a shiny surface to objects treated by the plasma. Droplets applied to the component or reference sample, when treated by isoionization, turn to a shiny metallic coating, in sharp contrast to the original colorless droplets. The metal film produced in the plasma is visually outstanding because of its reflectivity compared with the various colors of the object.


4. Dain pen test
Dain pen can directly draw a line on the product, can show the difference between the treatment and the treatment, different Dain pen to measure the results are different, need to be used according to the actual situation.
