摘要
Co-Re合金涂层是一极具潜力的抗高温烧蚀材料。利用HSC Chemistry 6.0软件对化学气相沉积Co-Re合金涂层进行模拟计算。分析结果表明,选择H_2-Re_2(CO)_(10)和H_2-Co(acac)_2为反应体系,在0～1 000℃的温度范围内ΔG均小于零;反应产物Re和Co含量随沉积温度的升高而增加,但沉积过程中会有C单质产生;制备Co-Re合金涂层的最佳反应温度区间为400～600℃。
Co-Re alloy coating is a potential high temperature ablative material. In this paper, HSC Chemistry 6.0 software was used to simulate the chemical vapor deposition of Co-Re alloy coating. The results show that within the temperature range of 0-1 000 ℃, the ΔG was less than zero when selected H2-Re2(CO)10 and H2-Co(acac)2 as reaction system. And, the content of Re and Co increased with the increase of deposition temperature. However, during the deposition process, C simple would produce. The optimum reaction temperature range for the preparation of Co-Re alloy coatings was 400-600 ℃.
