This research shows the chemical composition, morphology and structure of magnetic materials powders of crystalline alloys 79NM, 10SYU and amorphous alloy 71KNSR for their use as starting powders during plasma spraying ferromagnetic cores and magnetic shields with high permeability. The analysis of the structure and magnetic properties of plazmonapylennyh coatings is carried out. It has been established that the powders 79NM, 10SYU due to the oxide films at the grain boundaries have a magnetic permeability of about 100 G / Oe, and in coatings, it is in the region of 100–300 G / Oe for the magnetic field strength of from 0.5 to 3.0 Oe. 71KNSR alloy powders are differed from lack of crystalline oxide formations on the surface of the particles and the homogeneity of the structure and have a magnetic permeability of up to 9000 gauss / Oe. The maximum permeability of the deposited samples 71KNSR alloy powder coatings at a thickness of 200 to 600 microns made 2000–6000 Gauss / Oe for the magnetic field intensity 0.1–0.35 Oe.
