目前和建议使用的富氧和全流量补燃火箭发动机循环对预燃室和补燃室部件的材料选择提出了重大挑战。大多数材料在高压、流动的气态氧环境中燃烧，这些部件将经受这种环境。论述了“抗燃”材料的选择原理和方法。一系列筛选试验，包括促进燃烧，摩擦点火和颗粒冲击试验，以帮助材料的选择过程中描述。在氧气应用材料的最终鉴定中，建议进行与给定应用直接相关的组件测试。根据现有的数据，镍，铜和钴的纯和合金形式是领先的候选人在这一具有挑战性的环境中生存。这些材料可以保持耐燃烧性;然而，它们通常缺乏轻质结构应用所需的强度。考虑到这些选择，显然需要具有更高强度和优异阻燃性的材料。
The current and proposed use of oxygen-rich and full-flow staged combustion rocket engine cycles imposes a significant challenge on the selection of materials for preburner and turbomachinery components. Most materials burn in the high pressure, flowing gaseous oxygen environment to which these components would be subjected. A "burn-resistant" material's selection rationale and approach are discussed. A series of screening tests, including the promoted combustion, friction ignition and particle impact tests are described to aid in the material selection process. Component tests directly related to a given application are recommended in the ultimate qualification of a material for oxygen service. Based on existing data, Ni, Cu and Co in pure and alloyed forms are leading candidates for survival in this challenging environment. These materials may maintain bum resistance; however, they generally lack the strength desired for lightweight, structural applications. Given these few options, there emerges a clear need for materials with higher strength and excellent burn resistance.
