Bonding between foam core and metallic skin is a pre requisite for the technological application of aluminium foam as filling reinforcement material. An intermetallic layer formed at the interface during foaming should make the foam firmly fixed to the skin improving its bending and torsional strength and stiffness. The formation, growth and metallurgical properties of this layer are strongly related to the process parameters. This work aims to contribute to understand how some parameters and the possible correlations between them influence the process. DOE and ANOVA statistical techniques highlighted that argon flux helps the formation of a continuous layer, foaming time and temperature strongly affect its thickness and morphology.

Abstract
Bonding between foam core and metallic skin is a pre requisite for the technological application of aluminium foam as filling reinforcement material. An intermetallic layer formed at the interface during foaming should make the foam firmly fixed to the skin improving its bending and torsional strength and stiffness. The formation, growth and metallurgical properties of this layer are strongly related to the process parameters. This work aims to contribute to understand how some parameters and the possible correlations between them influence the process. DOE and ANOVA statistical techniques highlighted that argon flux helps the formation of a continuous layer, foaming time and temperature strongly affect its thickness and morphology.File | Dimensione | Formato | |
