Embodiment Construction

[0016] The above-mentioned and other technical features and advantages of the present invention will be described in more detail below in conjunction with the embodiments.

[0017] 1. Method summary:

[0018] Debug the instrument, carry out center positioning and curve calibration to make the instrument reach the best state. The sample needs to be cut into a sample block of appropriate size. The surface of the sample block should be flat and free of defects. After simple wiping to remove the surface dirt, the sample is installed in the sample chamber of the spectrometer , measure the intensity of the spectral line, and obtain the change curve of the intensity of each element with time, and analyze and calculate the curve to obtain the coating depth and coating quality of the galvanized sheet.

[0019] 2. Main equipment:

[0020] 2.1 Cutting machine, which can cut steel samples of different sizes in the cutting area

[0021] 2.2GDProfiler2 glow spectrometer

[0022] 3. Elect...

Abstract

The invention discloses a method for measuring depth and quality of plating of a galvanized plate through a glow discharge spectrometer and aims to provide a method for rapidly, accurately and efficiently measuring the depth and the quality of the plating of the galvanized plate. The method comprises steps as follows: an instrument is debugged, center positioning and curve calibration are performed, accordingly, the instrument is in the optimum state, a sample is cut into sample blocks with appropriate sizes, the surfaces of the taken sample blocks are flat and don't have defects, the sample is arranged in a spectrometer sample chamber after surface dirt is wiped and removed, intensity of spectral lines is measured, a changing curve of the intensity of each element with time is obtained, the curve is subjected to analysis and calculation, and the depth and the quality of the plating of the galvanized plate are obtained.

Description

technical field [0001] The invention relates to the technical field of surface analysis, in particular to a method for measuring the coating depth and coating quality of a galvanized sheet by using a glow spectrometer. Background technique [0002] In recent years, scientists have found that in many cases, the composition and structure of the material surface have a special effect on the properties of the material, so the importance of surface analysis and layer-by-layer analysis has increasingly attracted analysts' attention. The methods commonly used for surface analysis include Auger Electron Spectroscopy (AES), X-ray Photoelectron Spectroscopy (XPS), Secondary Ion Mass Spectrometry (SIMS) and Glow Discharge Emission Spectroscopy (GD-OES). Due to the difference in equipment price, analysis accuracy and precision, the application in daily analysis is not necessarily the same. Glow discharge emission spectroscopy analysis technology has been widely used in the research and...
