The mechanical alloying and other technologies were utilized to prepare Ag,Ag/Cu and Ag/Ni powder materials and electromagnetic shielding coatings. These powder materials have excellent conductivity,and their morphologies are flake and fine. The lower resistance and surface resistance of the coatings could meet the requirements of using. The electromagnetic shielding effectivenesses of the coatings are superior,in the frequency range of 100 kHz to 1.5 GHz,they are from 30 dB to 90 dB. The usefulness of electromagnetic shielding coating is theoretically analyzed.
