The article presents the study of the influence of a nitrogen gas medium on the structural-phase composition, fatigue strength and biocompatibility of porous SHS-TiNi alloys. It was established by the threepoint bending method that porous samples do not withstand more than 400 thousand cycles. The SEM method has shown a presence of large number o f cracks and brittle inclusions on the fracture surface. XRD analysis has established that formed nitride phases on the surface improve biocompatibility of porous TiNi alloys. Confocal microscopy showed that the cells have covered surface of porous TiNi framework is 90%.
