How can a plasma treatment be proven?

The  indicator labels and the plasma indicator-metal connection offer users of plasma systems the possibility to see at a glance whether a plasma treatment has taken place. 

The  indicator labels  and the  plasma indicator-metal connection  offer users of plasma systems the possibility to see at a glance whether a  plasma treatment has  taken place. The tests are carried out practically  without time . They can be used in  every  plasma system for  every  treatment whether  cleaning, activation, etching  or  coating  . Even after weeks and months, the indicators mark the plasma treatment already carried out on your product or semi-finished product. 

Indicator labels

The adhesive label is a  specially  coated film that can be placed directly in the  chamber as a reference  or  glued to the  component . As soon as the dark indicator point has disappeared, the plasma treatment is  successfully  completed. The indicator labels can also be used for a  system  test. A label is placed in the empty vacuum chamber and the plasma ignited.   

ADP plasma indicator

The plasma indicators are adhesive labels with a special fabric. If the plasma process was successful, the tissue dissolves.
The adhesive label is attached to a component or a dummy as desired. This is exposed to the plasma jet as a reference, and the indicator has no effect on the actual plasma process or on the component itself. The tissue is destroyed during treatment.

Plasma indicator metal connection

The plasma indicator is a  liquid  metal compound that decomposes in the plasma so that the surface of the plasma-treated object has a  shiny metallic  surface. A  drop  applied to the  component  itself or a reference sample  turns into a shiny metallic layer during plasma  treatment, which forms a clear contrast on most surfaces and to the originally colorless drop. The golden, shiny metal film created in the plasma stands out optically  from any color of the object due to its reflectivity .
