Mechanical Properties and Corrosion Resistance of TaC Ceramic Prepared by Hot Pressing Sintering AITranslate
Abstract AITranslate
TaC ceramic materials were fabricated by hot pressing sintering and the effect of sintering temperature on the microstructure and mechanical properties of the ceramics was investigated.The corrosion resistance experiment in molten cerium was carried out with coating method,and scanning electron microscopy(SEM)and X-ray diffraction(XRD)were used to characterize the properties after corrosion,in order to reveal the corrosion mechanism.The results show that with the increase of sintering temperature,both the density and mechanical properties of TaC ceramics are improved to some extent.Its density reaches 98.29%and mechanical properties achieve the best at the sintering temperature of 2 100℃.In the anti-molten cerium corrosion experiment at 1 400℃,the corrosion rate of TaC ceramic decreases with the extension of corrosion time,and its corrosion rate reduces to 0.65μm/h after corrosion for 10 h.There is no change in phase of TaC ceramics after corrosion,but the corrosion mechanism gradually changes from initial crystal boundary corrosion to grain corrosion.
