Carbonyl Metal Powders for Coating War Planes
Absorbing material can be used in airplane coating for reducing radar reflection and reducing radar signature, to improve mission success rate, survival probability of warplanes and stealth operations in enemy range. Therefore, it will be of great significance in developing new type absorbing materials.
According to loss mechanism, microwave absorption can be divided into resistor type, dielectric type and magnetic medium type. Based on resonance and magnetic hysteresis loss principle, magnetic medium absorber can be used in reducing electromagnetic wave, in which the representative materials mainly include ferrite and micro metal powder. Micro metal powder mainly includes carbonyl iron powder, carbonyl nickel powder, permalloy, cobalt nickel alloy and so on.
