Summary:Заглавие с экрана
Surface alloys of system Ti-Y with different yttrium concentration have been synthesized. Formation of two-phase mixture alpha-Ti+alpha-Y has been revealed. It was shown that a structure of grained type was formed at volume fraction of alpha-Y(50-60) %. Elongated interlayers of alpha-Y are seen along the grain boundaries, and two-phase (alpha-Ti+alpha-Y) structure of a cellular crystallization with cell sizes of~0.5 mum -in a grain volume and nano-sized particles -along the boundaries. A structure of nanosize lamellar eutectics with a relatively small grain size (10-20 mum) is formed at volume fraction of alphaY (70-80) %. It was shown that a surface alloy formation is accompanied by a multiple decrease of friction coefficient and wear speed, and microhardness increase of modified layer in comparison with the similar titanium one.
