MAX Phase Material Properties
Mechanical properties
The unique crystal structure and bonding mechanism of MAX phases determine their excellent mechanical properties, high flexural strength, and fracture toughness. Additionally, due to the influence of nanoscale dimensions, MAX phase coatings exhibit relatively high hardness (10-20 GPa). V2AlC powder is a typical representative of the MAX phase. Mohsen et al. [52] successfully synthesized nearly impurity-free V2AlC powder phase by microwave sintering a powder mixture of V-Al-C with a molar ratio of 2:1.5:1 at 1300°C. It exhibited a high flexural strength of 189±21 MPa and a Vickers hardness of 445±18 HV.
Tribological properties
The MAX phase is a thermodynamically stable nano-layer, and M-A is bonded by weak metal bonds. Based on these characteristics, the MAX phase material may have lubricating properties similar to layered materials such as graphite and MoS2. And the MAX phase material will be selectively oxidized to form M and A oxides during the sliding process. These oxides play an important role in the tribological behavior of the material, and the load, sliding speed and the microstructure of the material will all affect the formation of oxides.
High temperature oxidation resistance
In the unique layered structure of the MAX phase, M-X is bonded by strong covalent bonds, which are not easy to be destroyed, while M-A is bonded by weak metal bonds, which makes the A element have a high diffusion activity. Selective oxidation easily occurs in the environment to form a dense protective oxide film.
