The authors analyzed the existent doping techniques for titanium filler wire with the usage of oxygen for welding deposition of hardwearing coatings onto the surface of titanium parts by means of nonconsumable electrode arc welding. Equipment for micro-arc oxidation of welding titanium alloy wire was developed; it allows to regulate oxygen content in the welding wire smoothly and, therefore, the deposited metal hardness along with automation of doping the wire with oxygen and the following welding deposition.

The problem of conflict-optimum counteraction of small groups of aircrafts in the form of two-stage procedure of ranking-allocation and conflict optimization by Nash for obtaining the stable-effective decision in the shape of matrix of conflict-optimum target setting is considered. Calculating time in the case of the exhaustive search is far from real-time, therefore the procedure of thinning of the counteraction effectiveness matrix is proposed, as a result the operating speed for the problem of counteraction of 4-by-4 aircrafts is rising twenty-fold.
