In this work, the Ti-Al system coatings are considered. The coatings were applied using the NNV 6.6-I1 unit, using two single-component cathodes. During the coating process, a mixture of nitrogen N2 and acetylene C2H2 reaction gases was supplied to the chamber in the following ratios:1:4, 2:3, 3:2, and 4:1. The microhardness of the samples was determined, and the values were compared with the microhardness of the uncoated and TiAlN-coated samples. It was found that the sample with a coating obtained at the ratio of reaction gases N2:C2H2 = 2:3 has the highest microhardness. In the next stage of research, the chemical composition of the front surface of the cutting tool wasdetermined in detail using electron microscopy. After durability tests, it was determined that the mostwear-resistant coating when cutting metals with the studied samples is the coating obtained at theratio of gases N2:C2H2 = 4:1. doi 10.54708/19926502_2025_2941103Downloads
