MAX phase ceramics are an important class of novel three-dimensional crystalline nanocomposites with an interesting combination of metal and ceramic-like properties that have made these materials highly regarded candidates for numerous technological applications, including in extreme environmental conditions. Some tests have also shown that the MAX phases may exhibit an extraordinary radiation resistance, which could be attractive for application in the nuclear industry. In this contribution, titanium tin carbide was inspected. The Ti2SnC phase was synthesized as a thin film by low-energy ion beam sputtering and subsequent thermal annealing, and it was irradiated by high-fluence low-energy Ar ions to inspect its radiation tolerance. The experiment showed that by the 2-step method of ion beam sputtering with thermal annealing thin films (several tens of nm) of the Ti2SnC phase can be successfully fabricated. The bombardment with high fluence heavy ions results in modification of the composite microstructure, but it has only a limited impact on the crystallinity of Ti2SnC grains.
