Abstract CARLSON ALLOY NITRONIC 60 is a galling- and wear-resistant austenitic stainless steel that provides a significantly lower-cost alternative to cobalt-bearing and high-nickel alloys. Corrosion resistance is superior to 304 in most media. Approximately twice the yield strength of 340 and 316. Possesses excellent high-temperature oxidation resistance and low-temperature impact resistance. This datasheet provides information on composition, physical properties, hardness, and tensile properties. It also includes information on corrosion and wear resistance as well as forming.

The paper presents the results of studying the phase composition of iron-nickel alloys obtained by unsteady electrolysis. It was found that the use of a unipolar pulse current leads to a significant increase in the crystallization overvoltage at the crystallization front at the moment of the pulse action, which affects the component composition of the coatings. The phase composition of the alloys formed at the cathode differs from that shown in the iron-nickel equilibrium diagram.

The Impact

There are a variety of opinions regarding the influence of retained austenite and carbides on the properties exhibited by carbonitrided steels. In this paper, the development of a model marking relationship between phase composition, and properties of hardened carbonitrided steel has been presented. A summary of the impact of structure on properties is provided in Table 1. In the study reported here, the impact of thermal processing conditions on retained austenite and carbides was examined for carbonitrided and hardened 20 (C22), 20H (20Cr4), 15HN (17CrNi6-6) and 16HG (16MnCr5) steels. The models that are reported were experimentally validated. In particular, the results obtained for structure with respect to hardness and abrasive wear resistance were discussed for carbonitrided and hardened 20H (20Cr4) steel.

Wear And Corrosion

This study presents the effect of heat treatment on porosity, phase composition, microhardness, and wear and corrosion resistances of the thermal sprayed NiCr20 coating after sealing with aluminum phosphate. The annealing temperatures were varied in a range of 400 to 1000°C. The obtained results indicated the porosity of coating decreased with increasing the annealing temperature. After treatment at temperatures in range of 800-1000°C, more than 90% of initial pores in the coating were successfully filled with the sealants. The XRD data revealed not only the formation of new phases of other compounds, but also the interaction between coating and sealant. After heat treatment, wear resistance of coating was 12 times higher than that without heat treatment. The corrosion test in H2SO4 solution indicated that the presence of sealant in coatings increased their corrosion resistance. From these findings, application of these NiCr20 coatings to protect steel against wear and corrosion appears very promising.

Abstract The main purpose of the investigations was to develop the phase composition of the composite assuming that the component selection criterion will be the formability of piston work surfaces during the machining. Wear resistance under the friction conditions was assumed as the additional parameter for the assessment of composite material. In the study were used AlSi7Mg/SiC+Cg and AlSi7Mg/SiC+GR hybrid composites prepared by the stir casting method.

The influence of the parameters of laser processing of copper plating deposited by explosion welding and subsequent rolling on the titanium surface on the structure and phase composition of the coatings is studied. It is shown that alloying titanium with copper leads to the formation of intermetallic compounds (titanium cuprides) in the remelting zone, which contributes to a significant increase in the wear resistance of the surface layer. When tested for wear on a fixed abrasive, the wear resistance of the coating is 2 times higher than that of VT1-0 titanium alloy.

γ-Fe/(Cr, Fe)7C3 lamellar eutectics reinforced the composite coating was deposited onto the 16Mn steel surface to enhance its surface hardness and wear resistance. The microstructure, phase composition, microhardness as well as wear resistance of the cladding coating were explored. Results indicated that the coating showed the dense and defect-free metallurgical bonding with the substrate and mainly consisted of (Cr, Fe)7C3, γ-Fe/(Cr, Fe)7C3 lamellar eutectic, B4C and carbon fibers. (Cr, Fe)7C3, B4C and carbon fibers were tightly embedded in the γ-Fe/(Cr, Fe)7C3 lamellar eutectics matrix. The microhardness and wear resistance of the coating compared with that of the substrate were highly improved by nearly 5 and 3 times, respectively.
