Technical Field

The invention belongs to the technical field of glow spectrum analysis, and particularly relates to a method for positioning analysis in glow analysis.

Background

The types of first steel sheet products are more and more complete, the yield is higher and higher, and the mass production of new products such as zinc-aluminum-magnesium, aluminum-silicon and the like is realized.

Glow discharge spectral analysis is applied to the detection of the thickness and weight of the coating on the surface of various sheet samples such as zinc-aluminum-magnesium, aluminum-silicon, galvanized sheet, tinned sheet and the like, the thickness and weight of the passivation layer, chemical components and the like, and provides a large amount of effective data for scientific research and development.

The basic principle of glow discharge spectrometry is that a sample is used as a cathode, argon is ionized by high pressure in a copper anode, argon ion flow impacts the surface of the sample used as the cathode, elemental atoms on the surface of the sample are stripped layer by layer, the stripped elemental atoms are excited in the anode to emit light, light beams are introduced into a light chamber, and after decomposition by a light splitting system, the intensity of characteristic spectral lines is detected, so that the elemental composition distribution of the sample from the outside to the inside can be obtained.

When a glow discharge spectrometer, i.e., model GDS850A of the company lycra corp, is used for sample analysis, a surface to be detected needs to be adsorbed on an anode port, the diameter of the anode port is 4mm, the area, corresponding to the anode port, of the sample surface with the diameter of 4mm is an analysis area, the diameter of a sealing ring on the outer edge of the anode port is 12 mm, and the diameter of the sample is generally 30-50 mm. In addition, the sample analysis chamber has a narrow space, and when a sample is adsorbed to the anode port, the analysis position cannot be accurately positioned to a certain position on the surface of the sample. However, samples such as zinc-aluminum-magnesium, aluminum-silicon, and galvanized sheet often form abnormal regions with different colors or lines on the surface of the sample due to the influence of production process, environmental conditions, and the like, and researchers often need to designate a certain determined region for glow spectrum analysis to observe the difference between the surface element components of the abnormal region and the normal region.

Therefore, there is a need to identify a method for performing a localization analysis in a glow analysis.
