| Popis: | This study focuses on the temperature capability of CoWO4 as the oxidation protection layer of ferritic stainless steel (FSS). The thermogravimetric-differential thermal analysis revealed that until CoWO4 started to melt at 1297 °C, little mass change was observed. In addition, the coefficient of thermal expansion of CoWO4 was 11.5 ± 0.2 (×10−6 K−1), which was similar to that of FSS, evidencing its good thermal stability and compatibility for the protection of FSS. The oxidation test of the Co–W coated specimens at 700 °C – 1000 °C in air confirmed effectiveness of the CoWO4 layer at T ≤ 850 °C. |
