Catalytic surfaces for hydrocarbon cracking and dehydrogenation have been known in the petroleum industry to become inactive after some use because of carbon or "coke" coating. The proposed research is directed toward using such coatings, preferably produced under conditions simulating the environment of such operating machinery as the "adiabatic" diesel engine, as self-replenishing solid lubricants. Continued wear of the carbon coatings would maintain catalytic activity of the substrate. The operating temperatures in the piston-ring/cylinder area of such a diesel engine and the preferred temperature of catalytic coke generation by some transition metals happen to coincide in the 500-600 C range. Adsorption of combustion chamber gases on these carbons would further reduce friction and wear. The same transition metals, in alloys or in or on ceramics are also close to hydrocarbons. The suggested research program will use pin-on-disk testers on reproducibly prepared samples and determine the friction and wear rates, rates of carbon formation and rates of carbon oxidation to help guide the design and materials selection for high temperature lubrication in an engine environment.

由于碳或“可口可乐”涂层，已知石油行业已知碳氢化合物裂解和脱氢作用的催化表面变得不活跃。 拟议的研究旨在使用此类涂层，最好是在模拟“绝热”柴油机等操作机制的环境下生产的，作为自我剥削的固体润滑剂。 碳涂层的持续磨损将维持基材的催化活性。 这种柴油发动机的活塞环/气缸面积的工作温度以及某些过渡金属的催化焦焦生成温度在500-600 c范围内的重合。 这些碳燃烧室气体的吸附将进一步减少摩擦和磨损。 合金或陶瓷中的相同过渡金属也接近碳氢化合物。 建议的研究计划将在可重复准备的样品上使用烟道测试仪，并确定摩擦和磨损速率，碳形成速率和碳氧化速率，以帮助指导在发动机环境中的高温润滑的设计和材料选择。
