Study of Titanium Compounds Used in the Manufacturing of Standard Specimens for X-ray Fluorescence (English)
Abstract [en]

SECO Tools manufactures tool inserts for all types of metal cutting machining. (Ti,W)C is a common raw material used in the production. At arrival, the material (Ti,W)C is always analyzed. Titanium has previously been analysed with x-ray fluorescence spectrometry, but as the calibration has previously been performed with two different types of titanium (rutile and metallic titanium), the results has differed. Because of that, this thesis project has been devoted to analyze titanium, to find the best titanium compound for producing standards.

The work has been performed using literature studies and many experiments in the laboratories at SECO Tools inFagersta,Sweden. This project has included about ten working weeks. In this report the analysis methods of x-ray fluorescence spectrometry and spectrophotometry is described, as the methods has been used in the experiments.

A big problem that was discovered during this project was the big standard deviation of results for the method used for analysing titanium with x-ray fluorescence. Because of that, much time of this project has been devoted to experiments trying to reduce the standard deviation between the samples, as this is vital to performing a reliable calibration. A variety of experiments has been performed without reducing the standard deviation between the samples to below 0.2 % -units for the (Ti, W) C-samples.
