The Fe66Cr10Nb5B19 alloy coatings with high hardness (≈850 HV300), low porosity (less 3 %), low content of crystalline phase (less 2.5 wt.%), elevated nanohardness (average value 13.7 GPa), and high wear resistance were obtained in a wide range of detonation spraying modes. The results of dry linearly reciprocating sliding wear tests of coatings carried out according to ASTM G 133-05 are presented. The wear resistance of coatings obtained at an explosive charge of 50 - 70 % is significantly higher than that of stainless steel. The similar values of volume scratches of Fe66Cr10Nb5B19 coatings obtained at an explosive charge of 40 - 70 % are attributed to the similar values of porosity and the content of the crystalline phase. Scratch and spalling are the main mechanisms of coatings destruction during scratching with a diamond tip.
