Atomic level out-diffusion and interfacial reactions of MAX phases in contact with metals and air

The outwards diffusion of Al and Si elements in Al-containing and Si-containing MAX phases endows them one natural advantage to form anti-oxidation layer and strong interfacial bonding strength with different materials, including metals and ceramics. This magic phenomenon allows MAX phases to be use...

Description
Summary:The outwards diffusion of Al and Si elements in Al-containing and Si-containing MAX phases endows them one natural advantage to form anti-oxidation layer and strong interfacial bonding strength with different materials, including metals and ceramics. This magic phenomenon allows MAX phases to be used in different areas, such as diffusion and fusion welding, coating and laser cladding layer. In order to give one comprehensive and systematical summarization, this review covers important research work on the atomic-level interfacial evolution of Al-containing and Si-containing MAX phases in air or with metals. This will provide an effective guidance for researchers to select the type and adjust the proportion of A-site elements in MAX phases in reference to the applied circumstances. The interfacial structure between Al-containing and Si-containing MAX phase coatings and metals matrix will be reasonably realized.
