Beschreibung
Zusammenfassung:	The invention discloses a microwave attenuation alloy powder material, a microwave attenuation alloy-ceramic composite powder material, a microwave attenuation coating and a preparation method. The microwave attenuation alloy powder material comprises the following components in percentage by weight: 15-25% of Cr, 3-8% of Al, 0.2-5% of Co, 0-0.8% of Si and the balance of M, m is one or two of Fe and Ni. The microwave attenuation alloy-ceramic composite powder material comprises the following components: 55-65% of a microwave attenuation alloy powder material and 35-45% of attenuation dielectric ceramic powder. The microwave attenuation coating is prepared from the microwave attenuation alloy powder material or the microwave attenuation alloy-ceramic composite powder material through an atmospheric plasma spraying process. According to the invention, the electromagnetic microwave reflection loss and the effective bandwidth of the material are effectively improved by selecting and compounding the alloy componen
