Abstract The method of Thermoreactive Electrospark Surface Strengthening (TRESS) is presented in this work. Thus the process of coating formation becomes a less energy consuming one as compared to the basic technology of the electrospark alloying. The additional heat of the chemical reaction of the synthesis final products formation on the substrate contribute to the increase of thickness and continuity of the coating, to the diminution of the inner tension due to the smoother concentration gradients through the coating thickness. The opportunities of TRESS method are exposed with the example of the FGM wear- and heat-resistant coating formation on the base of NiAl, TiAl. FGM diamond containing coatings production by the said method is presented. Optimal conditions and technological parameters for diamond containing coatings deposition is found. The masstransfer kinetics, the coating structure and properties were studied.
