Abstract
The invention discloses a method for improving the measuring accuracy of common brass through an X-ray fluorescence spectrum, belonging to a measuring method. The required specific parameters are as follows: (1) controlling the surface roughness of a sample; when the common brass is turned, adopting a high-speed steel turning tool, controlling the feeding rate each time to be smaller than 0.2mm so as to enable the roughness of the sample to be below 10mum; (2) on an X-ray fluorescence spectrum instrument, according to the influenced degrees of different elements, calculating the following formula and applying the formula in the operation of the instrument; and according to the formula that Cu+Zn+other elements=100%, and the Cu+Zn=99.88%, and measuring the fluorescence intensity of each element, and calculating the contents of the elements such as Cu, Zn and the like by the fluorescence spectrum instrument according to the formula. Compared with the prior art, the method for improving the measuring accuracy of common brass through the X-ray fluorescence spectrum has the advantages that the element contents are accurate, the accuracy and the precision are improved greatly, the differences of people are reduced, and the like, thus having good promotion and application values.
Description
Technical field
The present invention relates to a kind of method, especially a kind of method that improves simple brass at the X-ray fluorescence spectra accuracy of measurement.
Background technology
The Xray fluorescence spectrometer analysis is a kind of relative analytical approach; Under the same conditions promptly, measure the x-ray fluorescence intensity of element in the testing sample, compare with the x-ray fluorescence intensity of standard model; By the constituent content of standard model, calculate the content of element in the testing sample.Therefore, must guarantee that consistent physical property is as far as possible arranged between standard model and the testing sample; But in real process, all have during each personnel's sample preparation than big-difference.When on the Xray fluorescence spectrometer device of our factory, testing simple brass; When the different operating personnel test same sample; The constituent content difference is bigger, and all elements content addition that the operating personnel that have measure is greater than 102%, but the element sum that some operating personnel measures is less than 98%.At present, good solution is not also arranged.
Summary of the invention
Technical assignment of the present invention is to above-mentioned deficiency of the prior art a kind of method that improves simple brass at the X-ray fluorescence spectra accuracy of measurement to be provided; It is accurate at the composition that the method for X-ray fluorescence spectra accuracy of measurement has each element that this improves simple brass; Accuracy and degree of accuracy improve greatly, the characteristics that personnel's otherness obtains alleviating.
The technical solution adopted for the present invention to solve the technical problems is: it comprises the surfaceness of (1) control sample; When the simple brass sample of car system, adopt high-speed steel bit, and control each depth of cut less than 0.2mm, the roughness of sample is reached below the 10 μ m; (2) on the Xray fluorescence spectrometer device, the degree that is affected according to different elements calculates following formula, and is applied in the computing of instrument; Other elements of Cu+Zn+=100%, Cu+Zn=99.88%, the fluorescence intensity of each element that process is measured, the fluorescence spectrum instrument calculates the content of each element such as Cu, Zn automatically according to formula.
Of the present inventionly a kind ofly improve simple brass and compare with prior art in the method for X-ray fluorescence spectra accuracy of measurement; Have following outstanding beneficial effect: the composition of each element is accurate; Accuracy and degree of accuracy improve greatly, and personnel's otherness such as obtains alleviating at characteristics.
Embodiment
