New alloying systems development, which embraces strength, erosion, corrosion, and high oxidation resistance, are now in high demand in the aerospace industry. The request is the lowest possible density of the alloy, which increases the flying vehicle's fuel efficiency significantly in need as well. In the last decade, Titanium and its alloys occupy all aerospace manufacturers' primary production sectors, excepted as most stable and inert in human surgeries applications. All of that does not mention chemical applications as membranes material. However, this element, having high strength and comparatively low density, suffers corrosion in salted environments, has weak resistance to erosion, and oxidases already at a temperature range of 350-400 C. Many research works were dedicated to expanding titanium-based alloys properties to obtain the well-balanced composition of alloying elements to combine these properties. The main alloying elements are Nb or Zr, creators of reliable solutions with Titanium to keep relevant ductility. Minor addition of silicon increases potential corrosion and oxidation resistance. One of the strength improvement factors can be TiN and ZrN nanoparticles, along with microporous structure uniformly spreading in the material's body.
