Analysis of the efect of calcium content on machinability of alloys type AlSi7Mg0,3

Popis výsledku v původním jazyce

The choice of aluminum alloy for casting is subject to a number of basic criteria such as strength, shape, precision, surface quality, weight, corrosion resistance, etc. The structure, and in particular the mechanical, technological and chemical properties of aluminum alloys type Al - Si (silumines) may be affected primarily by modification and addition of the inoculants. The paper deals with the research of the field of new AlSi7Mg0.3 alloys with different calcium content and especially the machinability of the alloy. For experimental purposes, an aluminum alloy from the group of the hypoeutectic silumin AlSi7Mg0.3 was used. Alloying took place using calcium in the form of AlCa10 alloy. A total of 4 melts were cast. The first without the addition of AlCa10 pre-alloy and the other three with graduated calcium, up to 0.1%, 0.5% and 1% Ca. The specimens thus prepared were subjected to a spectrographic analysis of the chemical composition to confirm the added calcium content. Subsequently, an analysis of the technological properties and especially of the machinability was carried out. In the last part, there were evaluated the chips produced during the machining of experimentally produced alloys. To measure the chip size, it is possible to determine the sludge effect on the shape and size of the chip, as only certain types of chip are required during processing, namely those which are most suitable for the continuity of the machining process. Another reason for chip analysis was the change of chip shape in the case of wear of the cutting tool during the cutting process. This topic is currently very topical in view of the high requirements of material parameters, especially in the automotive industry.
