Hot corrosion mechanism of layered ternary ceramics

1 Hot corrosion mechanism of Ti3SiC2 against various molten salts 

Liu et al. [76] also investigated the hot corrosion behavior of Ti3SiC2 in mixed salt of 68 at% K2CO3 and 32 at% Li2C03 at 650-850°C. At 700-

2 Hot corrosion mechanism of Ti3AIC2 and Ti2AIC against Na2S04 

Several hot corrosion mechanisms including sulfidation, acid-basic dissolution and electrochemistry have been proposed. No matter what the mechanisms are, it is important to understand the character of Na2S04 first. Na2S04 is an electrolyte, which follows the following equilibrium
