By "flash" method at the installation of vacuum evaporation the thin Nd-Fe-B layers of 100 nm <= d <= 1000 nm were obtained on glass support. The structure and microstructure of the thin Nd-Fe-B films was studied by X-ray diffraction analysis (XRD), scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS). The study of the specific magnetization temperature dependences of the Nd-Fe-B films on the glass substrate in the 80 <= T <= 800 K temperature range by ponderomotive method showed that the magnetization of the layer of d >= 1000 nm thickness are comparable to those for powder samples. The magnetization of film with d < 100 nm thickness at 100 K does not exceed 85 angstrom m(2) kg(-1). In such films the long-range structural order is destroyed. The values of the coercive force and magnetic saturation field of Nd-Fe-B thin layers are determined. The corrosion process of the thin Nd-Fe-B films magnets was studied experimentally in 3.5 wt% NaCl solution. X-ray photoelectron spectroscopy (XPS) analysis showed that the different electrochemical corrosion performance was associated with the ability of the thin films to form a big and continuous Nd2O3 passive film, while the formation of Nd(OH)(3) lead to a decrease of the corrosion resistance.
