In-situ formation and ablation mechanism of dense and multilayered ZrB2-ZrSi2-MoSi2 ultra-high temperature ceramic composite coating on Ta-W alloy under plasma blame beyond 2000 ℃
Source abstract
Abstract
A dense and three-layered ZrB 2-ZrSi 2-MoSi 2 composite coating with continuous interlayer interfaces and a thickness of ∼270 μm was in-situ prepared on Ta-10 W alloy by plasma spraying and pack cementation. Subjected to plasma ablation at 9.8 MW/m² for 1000 seconds, the coating with a mass ablation rate of 0.0002 mg/s undergoes oxidation to form a skeleton-structured ZrO 2 and liquid self-sealing SiO 2 . During the ablation, the over-diffused silicon top layer of the coating with high silicon content and uniform phase distribution can produce relatively adequate SiO 2 to withstand the consumption for up to 1000 seconds, yielding excellent ablation resistance above 2000 ℃.
