Abstract:

Ni-Cr coating and Ni-Cr/ZrO2 gradated coating were deposited on C45 carbon steel by high velocity arc spraying and micro-plasma spraying to solve the high temperature oxidation problem of medium carbon steel components. The oxidations of Ni-Cr coating, Ni-Cr/ZrO2 gradated coating and C45 carbon steel substrate were carried out for up to 108 hours in air atmosphere at 1100°C. The oxidation behaviors were investigated after detailed examinations by thermal gravimetric analysis (TGA), x-ray diffraction (XRD) and scanning electron microscopy (SEM). Ni-Cr coating and Ni-Cr/ZrO2 gradated coating show similar and low dynamics curve near to the logarithms function. Surface observations with SEM and XRD reveal that the oxidizing surface of the C45 carbon steel substrate is mainly a loose spherical structure consisted of mainly Fe2O3 and Fe3O4. The surface structures of Ni-Cr coating and Ni-Cr/ZrO2 gradated coating after 108 hours oxidization are rather denser than that of C45 carbon steel, which can effectively improve the properties of the oxidation resistance of C45 carbon steel substrate.

Abstract:

The basic hypothesis of this article focuses on the study changes in deformation under the machined surface of stainless steels and steel C45 when drilling. The problem of drilling holes with diameter D=5 to 12.5 mm resides in the fact that 25 to 30% of these holes do not comply with prescribed requested requirements. This article presents the results of experiments focusing on the study of the damage process in helical drills with diameter d=8.0 mm when drilling into austenitic stainless steel DIN 1.4301 and steel C45. This study also includes an analysis of accompanying phenomena in the cutting zone by measuring some selected parameters.

Abstract:

This work presents investigations of cavitation properties of different austenitic microstructures formed by laser beam machining of X5CrNi18-10 and C45 steels. X5CrNi18-10 steel was alloyed with TiC and Mn powders and surface layer of C45 steel was enriched with Ni, Mn, Cr and Nb. For alloying the cw CO2 laser beam was used as a power source. Cavitation behaviour of produced layers was investigated in a rotating disc facility. The results reveal different susceptibility to plastic deformation and strain hardening degree of surface in the early stage of cavitation erosion.

Abstract:

The subject matter of the article are tribological and material tests of gas-nitrided constructional steels, including 38HMJ and AISI52100, cooperating frictionally with C45 toughened steel or 100Cr6 hardened steel. All friction tests were carried out using the standardized “3 cylinders – cone” method. The results of the obtained tests showed a slightly more beneficial effect of the cooperation of nitrided constructional steels with 100Cr6 hardened bearing steel.

Abstract:

Laser Surface Modification of Borochromizing C45 SteelIn this study the test results for borochromized C45 steel after laser surface modification were presented. Influence of laser heat treatment on the microstructure and microhardness of surface layer was investigated. The process of borochromizing consisted of chromium plating followed by diffusion boronizing. The laser heat treatment (LHT) of multiple tracks in the helical line was carried out with CO2laser beam. The technological laser TRUMPF TLF 2600 Turbo CO2of the nominal power 2.6 kW was applied. Borochromizing was carried out with laser power density q = 41.40 kW/cm2and at laser beam scanning rate v = 0.67 m/min and v = 2.016 m/min. Measurements of microhardness were conducted using the Vickers' method and Zwick 3212 B hardness tester. Microstructure observations were performed by means of an optical microscope Metaval Carl Zeiss Jena and scanning electron microscope Tescan VEGA 5135. After laser heat treatment with re-melting a three-zone layer was obtained, which included: re-melted zone, heat affected zone and a core. Influence of laser treatment parameters on thickness of melted zone and microstructure of the surface layer was tested. The microhardness tested along the axis of track of the surface layer after laser modification was about 800-850 HV. The results of tests showed influence of laser power density and scanning rate on microstructure and properties of borochromized layers.

Abstract:

The purpose of the paper was to test how the content of carbon and alloying elements in steels influence the structure and properties of boronized layers. The following grades of steels were used during the tests: C45, C99U, 41Cr4, 42CrMo4, 45SG, 50HS, 60G, and 102Cr6. In the process of boronizing, the two-phase layer of borides of FeB and Fe2B were obtained on the tested steels with a hardness from 1900 HV0.1 for boride FeB to 1600 HV0.1 for Fe2B, irrespective of the chemical composition of the core/substrate. As the kontent of carbon and alloying elements in steels increase, the structure of borides becomes more compact, and the needles are thicker. The richer in alloying elements the core and the more carbon in steel, the thinner is the boride layer. After boronizing, the layer of FeB and Fe2B with a thickness of approx. 110 μm for C45 steel to approx. 90 μm for 102Cr6 steel was obtained. The test results indicate that the brittleness of borides increases in steels with the addition of Cr, and it decreases in steels containing Si and Mn. The highest wear resistance was obtained in steel 102Cr6.

Abstract:

The wear resistance of diffusion coatings in conditions of specific pressures of 3, 7 and 10 MPa was studied. The boride coatings were prepared by means of diffusion methods using C45 steel as the substrate material. Research on the microstructure and redistribution of chemical elements on wear surface of a borided layer was carried out. It was found that the boride coatings should be used under a specific pressure of 7 MPa. It was found that the wear of friction couple coating of steel C45 under specific pressure of 3 MPa proceeds according to the oxidation wear mechanism, while under specific pressures of 7 and 10 MPa the abrasive wear prevails. The wear-induced segregation of atoms in coatings was studied using secondary mass-spectroscopy method (SIMS). Increased C, O, and B concentrations were noticed at the wear surface on depth from 50 to 2000 Å. The secondary wear-induced structure formation on the wear surface resulted in high wear resistance of diffusion borided coatings.
