Samples with thickness of 2, 3 mm and diameter 10, 42 mm were constructed of steel 0.55 % Fe, 0.45 % C with polished surface. The samples were tested by XRD (small angle X-Ray diffraction), SEM with EDX, AFM, scratch – tester REVETEST, tests of wear resistance and acoustic emission, nanoindenter before annealing. It was discovered that the size of nanograins varied from 3,3 nm to 8 nm by annealing at 500°, 800° and 1000°C. By dint of μ- PIXE were discovered the segregation process of impurities at the junctions of interfaces and at nanograin boundaries. Moreover as a result of the thermal annealing hardness of coatings increased on 18- 20 %.
