Title: Structural state scale-dependent physical characteristics and endurance of cermet composite for cutting metal

Abstract

A structural-phase state developed on the surface of a TiC/Ni–Cr–Al cermet alloy under superfast heating and cooling produced by pulse electron beam melting has been presented. The effect of the surface’s structural state multimodality on the temperature dependencies of the friction and endurance of the cermet tool in cutting metal has been investigated. The high-energy flux treatment of subsurface layers by electron beam pulses in argon-containing gas discharge plasma serves to improve the endurance of metal cutting tools manifold (by a factor of 6), to reduce the friction via precipitation of secondary 200 nm carbides in binder interlayers. It is possible to improve the cermet tool endurance for cutting metal by a factor of 10–12 by irradiating the cermet in a reactive nitrogen-containing atmosphere with the ensuing precipitation of nanosize 50 nm AlN particles in the binder interlayers.

  • Nearly defect-free nitride, carbide, and oxiceramic coatings have been deposited by a unidirectional dual large area filtered arc deposition (LAFAD) process. One LAFAD dual arc vapor plasma source was used in both gas ionization and coating deposition modes with and without vertical magnetic rastering of the plasma flow. Substrates made of different metal alloys, as well as carbide and ceramics, were installed at different vertical positions on the 0.5 m diameter turntable of the industrial-scale batch coating system which was rotated at 12 rpm to assess deposition rates and coating thickness uniformity. Targets of the same or different compositions weremore » installed on the primary cathodic arc sources of the LAFAD plasma source to deposit a variety of coating compositions by mixing the metal vapor and reactive gaseous components in a magnetically confined, strongly ionized plasma flow with large kinetic energy. The maximum deposition rate typically ranged from 1.5 {mu}m/h for TiCr/TiCrN to 2.5 {mu}m/h for Ti/TiN multilayer and AlN single layer coatings, and up to 6 {mu}m/h for AlCr-based oxiceramic coatings for primary cathode current ranging from 120 to 140 A. When the arc current was increased to 200 A, the deposition rates of TiN-based coatings were as high as 5 {mu}m/h. The vertical coating thickness uniformity was {+-}15% inside of a 150 mm area without vertical rastering. Vertical rastering increased the uniform coating deposition area up to 250 mm. The coating thickness distribution was well correlated with the output ion current distribution as measured by a multisection ion collector probe. Coatings were characterized for thickness, surface profile, adhesion, hardness, and elemental composition. Estimates of electrical resistivity indicated good dielectric properties for most of the TiCrAlY-based oxiceramic, oxinitride, and nitride coatings. The multielement LAFAD plasma flow consisting of fully ionized metal vapor with a reactive gas ionization rate in excess of 50% was found especially suitable for deposition of nanocomposite, nanostructured coatings. Potential industrial applications of this highly productive coating deposition process are discussed.« less
  • Recently developed grades of cermet cutting tool materials, physical vapor deposition (PVD)-coated and uncoated, were used to machine a high-strength and relatively difficult-to-cut steel at cutting conditions typical of finish machining. Comparative tests were carried out with chemical vapor deposition (CVD)-coated (TiC + Al{sub 2}O{sub 3}) carbide inserts at similar cutting conditions. The test results show that the PVD-coated cermet tools outperformed both the uncoated cermet and CVD-coated carbide tools at higher speed conditions due to their increased mechanical and thermal shock resistance as well as the high lubricity of the TiN coating layer. The coated cermet tools were rejectedmore » mainly due to the generation of poor surface finish on the machined surface after prolonged machining due to the increased tool-workpiece contact area, with increasing flank wear, which permits access for dislodged hard particles into the interface. Plastic deformation of the cutting edge of the coated cermet tools tends to dampen the machining operation, leading to a reduction in both the cutting and feed forces. 9 refs., 10 figs., 1 tab.« less
