Abstract

Purpose. Establishment of the elemental and quantitative composition of alloys - components of road milling cutters, which are used as working bodies for milling the road surface, by X-ray fluorescence analysis.Methods. To establish the chemical composition of alloys - components of cutters of a road milling cutter, WIRTGENW6/20X cutters and their domestic counterpart KZTS A6/20 were studied. The X-ray fluorescence method was chosen to study the elemental composition of the components of the road milling cutters. This method, based on the interaction of X-ray radiation with the analyzed substance, is the most effective and efficient method of analysis, which allows obtaining complete and reliable information about the elemental composition of complex samples in a minimum period of time without destroying them, while maintaining all the physicochemical properties, as well as without using a reference sample. The method is based on the correlation between the X-ray fluorescence intensity and the element concentration in the sample. As a result of irradiating the sample with an X-ray flux, a characteristic emission of atoms is created, which is proportional to their concentration in the sample. With the help of an express analyzer of metals and alloys - the Niton GOLDD spectrometer, experimental data were obtained on the composition of alloys - components of cutters of a road milling machine.Results. During the study, it was revealed that the components of the cutters are made from the following alloys:1. Cutter WIRTGEN W6/20X:- tip made of hard sintered alloy VK8;- housing made of structural alloyed steel 32G2;- spring sleeve of the cutter made of structural carbon steel 08ps;- washer made of structural quality carbon steel 60.2. Cutter KZTS A6/20:- tip made of hard sintered alloy VK8;- housing made of structural alloyed steel 38XV;- spring sleeve made of structural quality carbon steel 40;- washer made of structural alloyed steel 45G.Conclusion. The obtained research results can be used for subsequent processes of hardening or restoration of cutters of road milling machines.
