【 摘 要 】

Clad materials are a variant of the typical composites, which consist of two or more materials joined on their interface surfaces. Clad materials as metallic composite materials are developed for the needs of user because the single metal often cannot satisfy it application conditions. That is, the advantage of clad materials is that the combination of different properties of materials can satisfy both the need of good mechanical properties and the demand of users such as industrial consumer. The purpose of this study is to study structural aspects in aluminium 3003 clad material with 4343 alloy, after different cladding time. Generally, Al 3003 material is Al-Mn alloy which has superior ductility, but the strength and hardness are low. Aluminium series 4xxx material is Al-Si alloy with high strength and hardness, but low ductility. In our paper we determine the grain sizes of the coated aluminium alloys, before and after cladding, and also the corrosion potentials of these aluminium cladding alloys.
