摘要：
Elements for use as protecting fuel contacting surfaces of a gas turbine engine are protected from carbon deposition by heating the element in a nitrogen containing atmosphere for sufficient time to cause penetration and absorption of nitrogen into the grain boundaries of the alloy surface, which acts as a barrier between the hydrocarbon fuel and the catalytic elements in the surfaces.
