However, there is no standard sample of X-ray fluorescence instrument for copper-tin alloy electroplating layer on the domestic market at present, and the consistency between the spectral standard sample and the matrix of the sample to be tested is the premise to ensure accurate and reliable analysis results
Due to the characteristics of coinage materials, general companies do not invest in the development of such standard samples. Although there are cast copper-tin alloy spectral standard samples, there are no standard samples with high tin content. The matrix and structure of the blank cake are different, which is easy to cause interference during detection, and is not suitable for the spectral analysis of the coating composition of the electroplated copper-tin alloy electroplating blank cake

The main objective of the invention is to provide a spectrum standard sample with ideal gradient and uniformity. In particular, the invention relates to a manufacturing method of a copper-tin alloy spectrum standard sample used for detecting coinage coatings. The spectrum standard sample is manufactured by main steps of removing oil with an alkali, activating with an acid, rinsing, electroplating, cleaning, drying and storing. The copper-tin alloy spectrum standard sample has reasonable design, advanced preparation technology, good uniformity and reasonable contents and gradient. The copper-tin alloy spectrum standard sample can satisfy requirements of on-line rapid analysis and of corresponding coinage production.
Description
technical field [0001] The invention relates to a copper-tin alloy spectral standard sample, in particular to a copper-tin alloy spectral standard sample for detecting coinage plating and a manufacturing method thereof. Background technique [0002] The electroplated copper-tin alloy blank cake is based on a steel core, and is covered with a copper-tin alloy coating through bimetallic electroplating. The composition content of the copper-tin alloy coating is related to the quality parameters of the electroplating blank cake, and is also an important anti-counterfeit symbol of the electroplated copper-tin alloy coin. In order to ensure the copper and tin metal content of the electroplating layer, and to meet the needs of rapid analysis of process control, it is necessary to use fast, accurate, and high-efficiency spectroscopic instruments to analyze the chemical composition of the plating layer. The most widely used method at present is the X-ray fluorescence spectroscopic q...
