Description

Offered device is unique and based on registering potential difference between electrode of pickup and surface of metal to be tested. It is known that electrons emit from the surface of metal and create low temperature plasma above said surface. Defects on metal surface impact on electron emission. Due to this fact it is possible to define defects and stress level on the surface of metal parts. Air into space between pickup electrode and tested metal is ionized to measure potential difference. Signal from pickup is processed in computer and operator can see on the screen of display visualized color picture of stress zones disposition. There are 10 color zones, the most dangerous is red zone. Operator can also define quantitative values of stresses in three dimensions. Device is supplied with special software and the data base. It is portable and easy in use.

Benefits

Offered device provides:

• defining of critical deformation in stress concentration zones;
• monitoring of metal structure defects and forecast the duration of failure proof service life of machine and equipment;
• short time intervals between measurements;
• small error of measured components of a vector of relative deformations;
• long service life;
• reliability and simplicity of the use;
• visualization in colors stress condition of different zones of metal surface;
• identifying the type of metal;
• defining of tension state in composite coatings, evaluation of adhesive coating strength, optimization of coating technology process;
• quantitative evaluation of fat removing and cleanliness level of the component parts surface preparation for coating, bonding together, coloring and other technological operations;
• ability of measuring of speed of oxide films rising on metal surfaces.
