“…A particular feature of this treatment is the accumulation of high-melting MC type carbide phases in 3 mm nearsurface layer of the hard alloy. Due to extremely high cooling rate caused by electron-beam treatment, these phases remain fine-sized and evenly distributed [14,15]. At the same time, due to the reactions of synthesis of new refractory carbides in the liquid and solid phases, it is possible not only to avoid cracking the surface but also it creates a surface free from the cords of the layer with a hardness greater than the hardness of base to 300 HV, the depth of 3-4 mm [16][17][18].…”

One of the effective ways of strengthening hard alloys is the creating structure layers on their surface with the gradient distribution of physical and mechanical properties between the wear-resistant coating and the base material. The article discusses the influence of the near-surface layer which is modified by low-energy high-current electron-beam alloying and the upper anti-friction layer in a multi-component coating on the wear mechanism of the replaceable multifaceted plates in the dry milling of the difficult to machine nickel alloys.

“…The two-phase layer of the coating with AlTiCrN grain size of up to 5 nm, at the boundary of which a Si 3 N 4 amorphous phase is located, suppresses the coagulation of grains of the basic phase during both the coating deposition and the tool operation. The interphase boundaries, which are the zones of intense dissipation of energy, deflect the occurring cracks from the direction of spreading, slowing them down partially or entirely [36][37][38].…”

Abstract. One of the promising directions of hardening of high-speed steel tool is the creation on their surface of the layered structures with the gradient of physic-chemical properties between the wear-resistant coatings to the base material. Among the methods of such surface modification, a special process takes place based on the use of pulsed high-intensity charged particle beams. The high speed of heating and cooling allows structural-phase transformations in the surface layer, which cannot be realized in a stationary mode. The treatment was conducted in a RITM-SP unit, which constitutes a combination of a source of low-energy high-current electron beams "RITM" and two magnetron spraying systems on a single vacuum chamber. The unit enables deposition of films on the surface of the desired product and subsequent liquid-phase mixing of materials of the film and the substrate by an intense pulse electron beam. The article discusses features of the structure of the subsurface layer of high-speed steel M2, modified by surface alloying of a low-energy high-current electron beam, and its effect on the wear resistance of the tool when dry cutting hard to machine Nickel alloy. A significant decrease of intensity of wear of high-speed steel with combined treatment happens due to the displacement of the zone of wear and decrease the radius of rounding of the cutting edge because of changes in conditions of interaction with the material being treated.

“…Reducing machining energy requirements requires process forecasting. Rief et al [26] successfully used specific cutting force for a holistic analysis of specific energy consumption. On the basis of this brief review of the literature, it can be concluded that the study of cutting force has long been, and still is, the focus of interest for technology developers.…”

Increasing the efficiency of cutting operations while fulfilling the required (expected) quality of the parts constantly requires a thorough knowledge of the chip removal process. This is especially justified in the case of deviations from the usual (traditional) technological conditions or cutting data, both in terms of cutting theory and technique. This paper summarizes some of the results of a study of cutting force and cutting temperature in face milling. The technological analysis of face milling was performed by FEM simulation, which was compared and validated by measuring the cutting force. The chip removal of C45 rolled steel as a function of tool rotation was studied with two different depths of cut ap and feed rate fz so that at a constant nominal Ac cross section the ratios ap/fz were 0.1 and 10. The effect of the change of the cross-section and chip ratio is shown.
