Laser express-analyser of composition of metals and alloys

Description

Express-analyzer is created for carrying out the emission analysis of alloys of gold on the basis of low-energy laser (0.5 mJ). Duration of the analysis does not exceed 2.5 s that allowed combining analysis of the composition with the process of marking. Utilization of the created express-analyzer allows conducting formula check up of all processed products, and turning back to the laboratory methods of analysis at occurrence of doubts as for quality of the product only.

The designed express-analyzer can be integrated into already existing laser systems of dimensional material processing (laser marking, cutting, etc.) that greatly reduces cost of equipment for carrying out analysis.

On the basis of express-analyzer it is possible to associate the technological processes of the laser treatment of the product (cutting, engraving, etc.) with simultaneous analysis of the material formula.

Innovative Aspect and Main Advantages

The principle differences of the designed express-analyzer from standard spectrum analyzers consist in the following:

  • emission analysis of alloys is conducted by means of low-energy (up to 0.5 mJ) laser;
  • process of the spectrum analysis is combined with the process of engraving (cutting, welding);
  • the laser express-analyzer operates with already existing laser systems;
  • time spent on the analysis is minimal;
  • cost of express-analyzer is vastly low in comparison with similar spectrum analyzers.

There are no analogues in Ukraine. The rows of foreign companies release instruments of the similar sort. Their main disadvantages are: long time of the analysis (1 min. and more), impossibility of integration into industrial technological lines, high power consumption (from 1.8 kW and above because of usage of solid-state laser with complex system of cooling), great mass-dimension factor, comparatively high cost, difficulty of maintenance service in Ukraine.

Areas of Application

Metallurgical, machine-building enterprises. Quality control of import products. Jewelry branch.

Stage of Development

The half-industrial sample of the laser express-analyzer intended for measurement of concentrations of precious metal in jewelry. The designed express-analyzer is integrated into existing systems of laser stigmatizing.
