摘要
Abstract
The ZrC layer of coated fuel particle was successfully prepared in the fluidized bed coating furnace by chemical vapor deposition, using a gas mixture of C_3H_6, ZrCl_4 vapor, H_2 and Ar. It is indicated that the deposited ZrC layer has smooth and compact surface without obvious holes, clear interfaces with inner dense pyrocarbon layer, thickness of 35 μm. Composition and crystal structure analyses indicate that the main elements of ZrC layer are Zr and C, and the Zr/C molar ratio is close to 1:1. Stoichiomet-ric fcc-ZrC was obtained. And non-preferred orientation of grains was observed.关键词
