The article presents an innovative method of metallization of ceramics based on detonation spraying process. New approach consists on exposition of influence mechanical deliver of energy for joining process. In the D-Gun spraying process the energy necessary for deposition the metallic coating onto ceramic substrate is delivered mainly in mechanical way. In the described case, the titanium particles, shot from the spraying gun barrel, impinge onto AlN ceramic surface, and their kinetic energy is transformed into heat delivered directly to the zone coating/substrate joint being formed. The powder being sprayed is also heated to a high temperature, however, the high kinetic energy of the particles in the spraying stream is dominant for the distinguishing properties of the coating.Keywords: Detonation spraying, coatings, ceramics, metallization
