Abstract
In search for a compatibility of magnetic properties and corrosion resistance, a pseudo-ternary system Nd-(Fe1-x-yCoxNiy)-B was studied in forms of melt-spun ribbons and sintered bodies. It has been found that the double substitutions with 0.2≤x≤0.45 and 0.05≤y≤0.25 in the composition of ordinary NdFeB magnet yield good corrosion resistance and also preserve moderate coercivity values. A further small, substitution of Ti atoms for Fe atoms enhances the coercivity and makes the demagnetization curve rectangular. For example, (BH)max and iHc in sintered magnets of Nd15(Fe.585Co.3Ni.1Ti.015)77B8 have amounted to 34 MGOe and 10.4 kOe, respectively.
