## 4 Conclusions  
The compositions, structures and properties of three (Ti,Al)N coatings deposited on samples with different spatial arrangements in the chamber were compared. The three samples were located, respectively, opposite the evaporator with a titanium cathode, opposite the evaporator with an aluminum cathode and in an intermediate position between the two evaporators. The coating was deposited without rotating the turntable. The study of the coatings showed the following:

Moreover, the titanium content increases from 7.6 at.% to 89.7 at.%. The sample occupying an intermediate position between the aluminum and titanium plasma flows has a dominant titanium content (69.5 at.%) and a lower aluminum content (30.5 at.%). * In the coating deposited on the sample located opposite the aluminum cathode, a nitrided layer of about 250 nm in thickness is formed in the substrate. * The results of hardness changes show that the coating on the sample occupying an intermediate position has the maximum hardness (32.3 \(\pm\) 1.7 GPa). The coating on the sample located opposite the aluminum cathode has a hardness of 16.7 \(\pm\) 0.8 GPa. The hardness of the coating on the sample located opposite the titanium cathode is 28.5 \(\pm\) 1.1 GPa. * The results of the study of the resistance to destruction in the scratch test correlate sufficiently with the hardness data. The coating on the sample occupying an intermediate position has the best resistance to destruction (complete destruction is not observed under a load of 40 N). The coating on the sample located opposite the aluminum cathode has the lowest fracture strength (it is destroyed under a load of L\({}_{\text{C2}}\) = 14 N). The destruction of the coating on the sample located opposite the titanium cathode occurs under a load of 28 N.
* The coating on the sample located opposite the aluminum cathode shows a dent in the coating, accompanied by partial chipping along the groove boundaries. The coating on the sample occupying an intermediate position is characterized by brittle fracture with the formation of a crack network in the depth of the scribing groove and fragmentary chips at the groove boundary up to 50 \(\upmu\)m wide. The coating on the sample located opposite the titanium cathode is characterized by fracture as a result of extensive delamination. Therefore, a sufficiently high-quality coating can be obtained without rotating the rotary table, while it is possible to control the coating composition by changing the positioning of the sample relative to the evaporators. The purpose of this work is to change the ratio of elements in the coating and to vary and study the properties of coatings deposited under different conditions. In the absence of rotation, a coating with an individual composition and properties will be formed at each point in space. As a consequence, having carried out a full volume of research, it will be possible to create a three-dimensional scheme that allows for obtaining a coating with a clearly determined ratio of two (and in the future--three or more) elements.
