Abstract

This paper addresses structural changes of Al-Si coating depending on various heat treatment parameters. Al-Si coated martensitic steel is one of the most commonly used materials in automotive industry for structural parts. Describing transformation of Al-Si coating is necessary in order to understand the phenomena affecting the welding and adhesive bonding stability. Three various heat treatment cycles were used in order to prepare specimens which were later evaluated by scanning electron microscopy, X-ray diffraction and tensile testing. Changes of the phase composition of the coating and mechanical properties of the base material are discussed in the paper.
