Hot corrosion behavior of Yb2SiO5 coating in NaVO3 molten salt
Source abstract
Abstract
Abstract The corrosion interactions of Yb2SiO5 with NaVO3 molten salt in three states, namely, sintered bulk, as-sprayed coating and heat-treated coating, were studied at 1000–1300 °C. The as-sprayed Yb2SiO5 coating exhibited better corrosion resistance than the Yb2SiO5 bulk and heat-treated Yb2SiO5 coating. The amorphous phase in the as-sprayed Yb2SiO5 coating remarkably suppressed the corrosion process. Yb2O3 was crystallized from the amorphous phase after heat treatment at 1400 °C and promoted the corrosion reaction. Corrosion products of YbVO4, the eutectic phase of Yb2O3 and Yb2SiO5, and Yb8V2O17 were found on the corrosion surface. The composition and content of the corrosion products depended on the state of Yb2SiO5 and corrosion temperature. The corrosion mechanisms were discussed based on the state of the Yb2SiO5 material.
