“…In a detailed view, the rounding of the edges of both types of phases is visible. This indicates that the material has been heat treated prior to further processing [4]. Heat treatment is applied to improve the properties of the alloy.…”

The given paper deals with the wear of the tensioner which is produced from aluminium alloy and used of the motorcycle timing chain. This component was made due to the unavailability on the spare parts market. The AlMgSi1 alloy was chosen for this purpose, taking into account the requirements for producing of the tensioner. After production, the tensioner was put into operation where its functionality was regularly controlled. The suitability of the selected material was checked after the tensioner was removed. Possible damages and structural changes in the material were assessed using a scanning thermoemission electron microscope. Detection of the chemical composition of foreign particles trapped on the surface of the tensioner from engine oil during the operation was performed by EDS analysis.

“…Quantitative evaluations plasticity for given material is to obtain the most value of elongation for examined material, where is direct relation between elongation and deep-drawing where is validity that the highest value of elongation represents better deep-drawing of material. The main goal of this research work had been to obtain as high as is possible elongation for sheets made of AlMg3 alloy, and ascertained technological parameters production for this aim [10][11][12][13][14].…”

This work was focused on the research of the different variability production deep-drawing sheets made of AlMg3 alloy which could influence on their deep-drawing properties e.g. non alloying elements Fe, Mn, heat treatment parameters and structure with aim to judge ascertained and analyzed properties of the sheets. The mechanical properties, mainly the highest elongation, and the other parameters (grain size, metallurgical purity), were measured due to they had had the main influence on the deep-drawing properties of the sheets made of AlMg3 alloy. For this research work had been obtained 5 deep-drawing sheets made of AlMg3 alloy with different production than chemical composition and heat treatment with the aim to realized "complex analyze", and to find up the best variant for production technology with the high deep-drawing properties.

The tensioner with lock nut is an important part of the timing mechanism, which is often used in motorized engines. This component consists of a plurality of parts which are connected to each other by a threaded part. The threaded part of the tensioner serves to precisely adjust the position of its front part against the timing chain. This setting ensures the correct position of the guide part and thus the running of the motorcycle engine. The benefit of this research is the analysis of changes on the threaded part surface, which is important for correct working of the tensioner it is necessary that the threaded part fulfill its purpose. It is necessary to prevent its degradation or excessive wear. Scanning electron microscopy and energy dispersive spectroscopy methods were used to determine the wear of the threaded part of the tensioner. The evaluation focused on surface changes in the threaded part and the possible occurrence of foreign particles on the surface with respect to their material contrast and chemical composition.
