“…By metal powder addition, the sintering temperature is generally decreased to 1300-1550°Cs [1,2]. Cr 3 C 2 -NiCr cermets are preferred in metal cutting technology due to their relatively low sintering temperatures and low density compared to WC-Co/Ni or TiC-Mo [4][5][6][7]. The main problem in cutting industry is melting and removal of the metal phase from the structure and corrosion, followed by sudden fracture occurs.…”

“…The interest to these materials increases for their high corrosion resistance at high speeds and temperatures. Ni-Cr binder phase was selected due to its better corrosion resistance in relatively high temperatures [5,7]. As well known, another way to consolidate these type cermets is to sinter by hot pressing.…”

Cr3C2-NiCr type cermets are used in cutting technology for their low sintering temperatures and relatively low densities. Their high corrosion resistance at high cutting speeds and high temperatures increases the interest to these materials. In this study, a powder mixture of 75wt% Cr3C2 and 25wt% NiCr with a Ni-Cr ratio of 4/1 by weight was sintered at 1350°C as the master composite. 3 mol % Y2O3 stabilized tetragonal ZrO2 and 8 mol % Y2O3 stabilized cubic ZrO2 powders were added to study the effect of ZrO2 content on the mechanical and wear properties of Cr3C2-NiCr cermets at the same sintering temperature. SEM and EDX analysis were performed for identifying microstructures. Elastic modulus and microhardness of master and doped cermets were measured by impulse excitation technique and Vickers (HV10), respectively. Wear tests were conducted by ball on reciprocating flat method to characterize the wear properties.

The effect of sintering temperature (900-1300°C) on the interaction of Cr 3 C 2 with a Kh17N2 steel matrix is studied. It is shown that complex iron-chromium carbide of (Cr, Fe) x C y type forms during sintering. With increasing temperature, it undergoes a number of phase transformations. The following mechanism of Cr 3 C 2 dissolution in the steel matrix is established:The effectiveness of chromium carbide Cr 3 C 2 as a doping agent in producing wear-and corrosion-resistant materials was previously verified in [1][2][3]. Powder composites containing Cr 3 C 2 can be used to make tools and machine parts designed to perform in conditions of abrasive wear and in hostile environments and to deposit protective coatings on parts and mechanisms. The steel component of such materials and the proximity of linear expansion coefficients of the coating and the part promote strong and unstressed adhesion between them.The performance properties of the alloys in question are largely determined by the nature of interaction between carbides of the solid phase and the steel matrix during sintering. As a rule, this interaction leads to complex redistribution of elements between carbides and the matrix. To control the interaction of chromium carbide with the steel matrix, clear understanding of the nature and mechanism of this process is needed to limit the impact of temperature and time factors to the maximum extent.The published data on the interaction of chromium carbide with a metal matrix are incomplete [4][5][6] or mainly focus on the interaction of Cr 3 C 2 with an iron matrix [7]. The studies by Napara-Volgina and colleagues deal only with composites based on Kh18N15 austenitic steel with Cr 3 C 2 and MoS 2 additives. These data do not reflect quantitative changes in chemical composition of the carbide phase at different sintering temperatures.Our objective is to examine the variation in phase and chemical composition of chromium carbide particles in contact with a Kh17N2 chromium steel matrix and to establish the mechanism of their dissolution during heating.
