    Synthesis and modification of Ti2SnC nanolaminates with high-fluence 35 keV Ar+ ions

  • Original language description

    MAX phases are a group of ternary carbide or nitride phases with a nano-layered microstructure. Their general formula is Mn+1AXn with n = 1 to 3, where M is a transition metal, A is an A-group element (from IIIA to VIA), and X is either carbon or nitrogen. These carbides and nitride have unusual behavior combining the metal and ceramics in the sense of chemical, physical, electrical and mechanical properties. These properties can be explained with their anisotropic lamellar microstructures. Here, we report on study of thin Ti3InC2 (M3AX2) phases. The phases were synthetized by ion beam sputtering of single (Ti, In and C) elements at the Low Energy Ion Facility (LEIF). The ion beam sputtering was performed using the Ar+ ion beam with energy of 25 keV and the current of 400 μA. The thickness of the Ti3InC2 composite (measured by RBS/EELS) was found to be about 65 nm. After the deposition, the samples were annealed in vacuum at 120 °C for 24 hours in order to induce interphase chemical interaction and formation of the Ti3InC2 material. In order to evaluate the radiation hardness and other effects induced by ion radiation (e.g., morphology alteration), the Ti3InC2 samples were irradiated by 100 keV Ar+ ion beam with different fluences between 10-13 cm-2 and 10-15 cm-2. It was found that the low-level fluence of Ar+ ions (10-13 cm-2) does not induce any significant change in surface roughness, and also the crystalline structure is preserved. At higher fluences, however, the formation of the concentrated point defects within the lattice of nanocrystalline Ti3InC2, as well as a thin amorphous carbon shell can be seen. In view of these results, we can conclude that obtained Ti3InC2 (M3AX2) nanolaminates hold great promise for utilization in harsh environmental conditions and nuclear radiation.
