The Fe66Cr10Nb5B19 alloy coatings with high hardness (~850 HV300), low porosity (less 3%), low content of crystalline phase (less 2.5 wt%), and high wear resistance were obtained in a wide range of detonation spraying modes. The results of comparative dry linearly reciprocating sliding wear tests of the obtained coatings and stainless steel carried out according to ASTM G 133-05 are presented. The volume loss of detonation coatings obtained at an explosive charge of 50–70%, measured on an optical profilometer, is significantly lower than stainless steel. The main wear mechanisms of detonation coatings were fatigue and abrasion, associated with the particles delamination from the coating surface, that were abrasive particles afterward. The similar values of volume loss and average COF in the steady-state stage can be attributed to similar values of hardness and porosity of the coatings.
