“…This optimum coating thickness was 3-4 µm. Coatings with gradient properties Ti-(TiAl)N-(TiAl)N as it previously also showed the best result in turning steel C45 (HB 200) [20][21][22][23]. In this case the best result demonstrated when turning steel "thick" coating thickness of 8 to 12 µm.…”

“…During the deposition of the coating, the following parameters of the process were used An uncoated carbide tool and a carbide tool with traditional coating TiN, deposited through the use of standard vacuum-arc technology of arc-PVD, were used as an object for comparative studies of tool life. Prior to deposition of coating, all carbide samples, as well as a reference uncoated sample, were preliminary subjected to low-energy high-current electron beam and alloyed with the reaction of formation of hafnium carbide within a composite carbide on the surface [20].…”

“…A number of papers are devoted to various studies of multi-layered composite nano-structured coatings with three-layer architecture [16][17][18][19], as well as nano-structured coatings of different compositions [20][21][22][23]. In particular, the studies were focused on such systems as Ti-TiN-(TiCrAl)N [16,17], Zr-(Zr,Cr)N-CrN and Ti-TiN-(Ti,Cr,Al)N [18]; Ti-(AlCr)N-(TiAl)N, Ti-(AlCr)N-(TiCrAl)N, Zr-(AlCr)N-(ZrCrAl)N [19].…”

Abstract. The aim of this work was to investigate mechanical and cutting properties, as well as the nature of wear and failure of carbide cutting tools with modifying coatings of two types: nanostructured multi-layered coating Zr-ZrN-(ZrCrAl)N, applied through the use of the technology of filtered cathodic vacuum arc deposition, and multi-layered nano-structured and gradient coating Ti-(TiAl)N-(TiAl)N, applied through the use of the technology of LARC ® (Lateral Rotating Cathodes). It is found out that the both types of coatings under test significantly improve tool life of a carbide cutting tool. The studies of mechanisms of wear and failure of carbide tools with coatings under test, conducted at macro and micro levels, have identified their major differences and revealed their most preferable field of application. The carbide tools, equipped with cutting inserts with the nano-structured multi-layered coating under study, provided a significant increase in cutting properties (tool life) of the tool in comparison with the uncoated carbide tool and in comparison with the reference carbide tool with TiN coating. The tool with the coating Ti-(TiAl)N-(TiAl)N under study demonstrated the increased wear resistance during 30-35 min of cutting, and then, the process of coating failure and tool wear was sharply intensified. For the tool with coating Zr-ZrN-(ZrCrAl)N, the tests revealed more evenly-balanced wear during the whole operating time between failures. It should be noted that NMCC Zr-ZrN-(ZrCrAl)N are substantially thinner, and that fact predetermines their better resistance to failure because of crack formation, and the technology of its generation is more cost-effective.

“…7) in a crosssection show a presence of an 80 mm-deep hardened zone. At that, at a depth of up to 50 mm, the microhardness of HV 25 exceeds the microhardness of the substrate by 15 MPa, and amount to about 100 MPa. The increase in the microhardness may be explained by the influence of residual tensile stresses occurring during pulse heating.…”

“…The metal is applied as a coating, e.g., using magnetron spraying. After that, an exothermic chemical reaction is initiated, which is conducted under a thermal explosion by pulse heating the surface of the product [25][26][27]. At that, in the capacity of reagents, a rather wide range of substances, chemically active at high temperatures, may be used [28,29].…”

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.
