Abstract

Selective laser melting (SLM) is a promising technology for complicated configuration details manufacture. Al-Si alloys are the most investigated alloys in selective laser melting manufacture at the time. A mechanical, corrosion and operational performance of SLM and as-cast details are deeply vary because cast structure stands in stark difference to SLM structure. In this article a corrosion behavior of synthesized and heat treated Al–Si–Mg alloy is shown. Also the results of general and intergranular corrosion are shown. The corrosion behavior of AlSi10Mg aluminum alloy with additives of Cu, Zr, Al–Si–Mg system Ce directly depends on structure of a material which in turn depends on manufacturing techniques and modes of thermal processing. In a cast condition the material shows the lowered corrosion resistance owing to formation of large dentritny structure in the course of crystallization. Development of corrosion processes in an alloy made by a SLS method, depends on quantity, the
