Analysis of ALSI7MG0.3 alloys with calcium for surface roughness

Popis výsledku v původním jazyce

Machining of aluminum alloys is a frequently used technology for further processing of aluminum alloys into final products. Roughness and surface profile are among the basic indicators of surface quality. The infeed and cutting speed can also have a further influence on the roughness parameters, which significantly influence the direction of the primary plastic deformation region and thus affect the usable surface properties. The article deals with an experiment with machined alloy AlSi7Mg0.3 and other new alloys of the type AlSI7Mg0.3 with different calcium content. For experimental purposes, an aluminum alloy from the group of hypoeutectic silumin AlSi7Mg0.3 was used. The alloying was carried out using calcium in the form AlCa10 master alloy. A total of melts were cast. The first without the addition of AlCa10 master alloy and the other three with graded amounts of calcium, namely 0.1, 0.5 % and 1 % Ca. The paper describes the evaluation of the roughness of the obtained surface after machining these castings in the base alloy and in the alloys with calcium. The values of the parameters Ra, Rz and Rt were measured, where the parameter Ra is the most commonly used in common engineering practice, Rz is used mainly for the evaluation of the surface quality in the automotive industry and Rt is directly related to the material share, when the significance of this parameter for the surface evaluation increases. The experiment and measurements are part of more extensive research conducted at FSI UJEP.
