A series of specimens of WC-9Ni-xCeO 2 cemented carbides were prepared. The influences of CeO 2 addition and cryogenic treatment (CT) on thermal conductivity, thermal diffusion coefficient, and heat capacity of the alloys were investigated using a Hot Disk thermal constant analyzer, a X-ray diffractometer (XRD), and a scanning electron microscope (SEM) coupled with an energy dispersive X-ray detector (EDS). The results indicated that with the increase in CeO 2 content in WC-9Ni-xCeO 2 cemented carbides, the thermal conductivity and thermal diffusion coefficient first increase and then decrease. The change in heat capacity of the cemented carbides, however, does not show obvious regularity. CT tends to increase the thermal conductivity, thermal diffusion coefficient, and decrease the heat capacity of WC-9Ni-xCeO 2 cemented carbides. Notably, the degree of influence of CT on thermal properties of the cemented carbides with various CeO 2 contents is obviously different. After CT, with an increase in the CeO 2 content, the variation of amplitude of thermal conductivity decreases. Similar situations also appear in the other two kinds of thermal properties.

The purpose herein is to assess the impact of different combinations of cryogenic treatments and tempering regimes on tribological properties of Cr–V tool steel against a CuSn6 counterpart. Dry sliding wear experiments are performed using a pin‐on‐disk tribometer according to the Taguchi method. Tribological behavior is investigated under four process parameters at mixed levels: cryotemperatures (−75, −140, or −196 °C), tempering temperatures (170 or 530 °C), sliding velocity (0.064, 0.128, 0.1885 m s−1), and load (1, 5, 10 N). According to the analysis, the minimum friction coefficient is obtained by cryotreatment at −140 °C combined with 170 °C tempering, with a sliding velocity of 0.128 m s−1 and load of 10 N. For the minimum counterpart´s material adhesion level, cryogenic treatment at −196 °C followed by tempering at 530 °C, sliding velocity of 0.1885 m s−1, and applied load of 1 N are the optimum settings. The analysis of variance model shows that the load (39.2%) has statistical significance on the friction coefficient, while the load (59.1%) and tempering temperature (18.0%) have statistical significance on adhesion levels. The tribological behavior of the steel is explained by thorough microstructural examinations using scanning electron microscopy coupled with energy‐dispersive spectroscopy.
