In this paper, we describe the CCDS2000 detonation system and demonstrate its capabilities for producing insulating and wear-resistant alumina coatings. The dielectric strength of such coatings is above 25 kV/mm at thicknesses in the range 50–300 m. The resistivity of the coatings at a temperature of 20C and relative humidity below 59% is e > 2.67 × 1013  cm. As humidity increases, e drops sharply, by two to three orders of magnitude. The adhesion of the coatings to a steel substrate is up to 60–70 MPa, their microhardness is HV0.1 = 1522–1655, and their porosity ranges from 0.35 to 1.00%. Our results demonstrate that, to obtain electrical insulation coatings, it is reasonable to use a C2H2 + 2O2 detonating mixture, and that optimal wear resistance parameters can be obtained with a 0.69C2H2 + 0.53C3H6 + 2.51O2 mixture. Switching to the dual-fuel mixture ensures a fourfold increase in abrasion resistance and a 34% increase in erosion resistance.
