This effect increases the strength and stability of the cutting properties of the tool. The analysis of the character of changes in values of lines with different MPT modes showed that there is a value of magnetic field intensity in MPT for solid alloys. This field produces the maximum displacement of the cobalt phase's diffraction lines and increases the intensity of the line (100) Co, which equals approximately 1.8\(\cdot\)10\({}^{5}\) A/m. Finally, studies have shown that a cutting tool equipped with inserts from hard alloys WC85 TiC6 Co9 and WC92 Co8 has a resistance relative to the untreated WC92 Co8 higher by 183%, and WC85 TiC6 Co9--more than 200%. The process of wearing inserts from WC92 Co8 and WC85 TiC6 Co9 is characterized by the absence of plastic deformation in the cutting part's shape and the absence of cracking. An increase in the strength of carbide inserts for turning tools treated by the pulsed magnetic field was due to stabilizing the stresses balance in the cobalt phase. This effect also prevents the spread of destructive cracks and improves material strength. Experimentally Determining the Thickness of the Hardened Layer and the Surface Hardness after Nitriding  
The microstructure of diffusion layers obtained by nitriding various steels in the container with a nitrogen-containing substance is similar to the diffusion layers following traditional gas nitriding (Figures 1 and 2). An increase in the temperature leads to an increase in the thickness of the nitride layer. The curves' nature is the same for all investigated steels. However, the layer's depth strongly depends on the steel composition. For all the studied alloy steels, an increase in the nitriding temperature from 450 \({}^{\circ}\)C to 700 \({}^{\circ}\)C leads to an increase in the diffusion layer thickness from 0.15 mm to 0.28 mm (at the temperature of 450 \({}^{\circ}\)C), and from 0.45 to 0.70 mm (at the temperature of 700 \({}^{\circ}\)C). As is well known, the traditional long gas nitriding for 40-100 h layer thickness decreases with an increase in carbon and alloying elements contents in the steel. This fact is due to the coagulation, growth, and spheroidization of carbides and nitrides in alloying elements for such a continuous chemical-heat treatment. Notably, this process does not occur at short-term nitriding (up to 5 h). During this time, the alloying elements' carbides and nitrides do not have time to grow to full sizes which inhibits further nitrogen diffusion into the metal. The presence of carbon and alloying elements [42] increases lattice defects and accelerates diffusion [43]. Changes in the time of nitriding from 1 to 5 h lead to an increase in the depth of the diffusion layer from high-speed tool steel W6 Mo5 from 127 um to 210 um. However, increased exposure of up to 5 h to obtain a deeper layer is accompanied by increased brittleness. In this regard, notably, the brittleness of the layer is an essential issue. A fragile layer at work friction can peel; small particles that broke off, unable to continue to play the role of abrasive, contributing to the rapid wear. The great fragility of the layer and other properties of parts also decreases. Therefore, the optimal selectable exposure time is 1 h. The diffusion layer's total thickness is 127 \(\upmu\)m, and the nitride phase is formed with a thickness of 35-40 \(\upmu\)m. This phase relationship provides a significant performance of the cutting tool. Microhardness distribution on the depth of steels' diffusion layers after nitriding for 5 h at different temperatures showed that all steels' high hardness corresponds to 450-500 \({}^{\circ}\)C. However, the total thickness of the nitridded layer at such a temperature is insufficient.
