The doctoral thesis "Development of metal-ceramic nanostructured coatings for the hot section parts of a gas turbine engine" has been developed by Konstantins Savkovs for the degree of Doctor of Engineering. The scientific adviser is Dr.hab.sc.ing.Alexandrs Urbahs. Currently turbine blades are designed by using not only heat-resistant steels and alloys but also titanium alloys with sufficient high-temperature strength, low specific weight and high corrosion resistance. Intermetallic alloys of Ti-Al system are particularly promising. A significant disadvantage of these alloys is low heat-resistance at temperatures above 650ºC. This research work presents a physical model of developed ion-plasma three-layer coating system including intermetallic, conglomerate and nitride layers on the basis of Ti-Al-N – NANOKS – to improve the heat-resistance of titanium and nickel alloys. During the research the technique and technology of each of the coating component layers was developed. Vacuum equipment NNV -6.6-I1 was modernised to implement the developed technology for depositing dense, thin nano-coatings based on Ti-Al-N system. Experimental studies on oxidation of each of the coatings – intermetallic, conglomerate and nitride on titanium alloy VT1-0 were conducted. Evaluation of the heat resistance of these coatings in the temperature range from 600 to 825ºC was carried out. A series of multi-layer coatings with different thickness ratios of intermetallic, conglomerate and nitride layers on the compressor blades made of titanium alloy OT4-1 was developed and implemented. Comparative tests on the continuous heat-resistance of the coatings at a temperature of 730ºC for 320 hours were carried out and the process of their oxidation was analysed. A mathematical evaluation of the influence of each of the constituent layers of the coating on the overall heat-resistance was made and the ratio of individual layer thickness was optimized. The optimized coating was sputtered and exposed to a continuous heat-resistance test at a temperature of 730ºC for 450 hours; the process of oxidation was investigated with the help of electron microscopy.
