How about the oxidation resistance of Fecralloy fiber and metal fiber?

FeCrAl fibers and metallic fibers are two commonly used materials in high temperature applications due to their excellent oxidation resistance. 

FeCrAl fibers are composed of iron, chromium, and aluminum and possess a unique structure that consists of an outer alumina layer that acts as a protective oxide scale, a diffusion zone of aluminum and chromium, and an inner metal core. This structure provides the fibers with resistance to high temperature oxidation, scaling, and corrosion. Moreover, the high content of aluminum in the fibers results in the formation of a tightly bonded Al2O3 layer that enhances the mechanical integrity of the fibers, making them ideal for applications in harsh environments such as gas turbines, heating elements, and furnace linings.

Metallic fibers, on the other hand, are composed of alloys such as nickel, titanium, and cobalt that possess high temperature strength, creep resistance, and corrosion resistance. The fibers have good oxidation resistance due to the formation of protective oxide layers such as Cr2O3, TiO2, and NiO. They also have excellent thermal conductivity and light weight, making them ideal for applications in aerospace, automotive, and military industries.

In conclusion,FeCrAl metal fiber exhibit excellent oxidation resistance due to its unique structures and compositions. These materials are widely used in high-temperature applications where oxidation is a critical concern.
