Weather-resistant magnet powder and magnet produced by using the same |
摘要 |
<p>The objects of the present invention are to provide a highly weather-resistant iron-based magnet powder containing a rare-earth element, characterized by high coercive force in a practically important humid atmosphere, a resin composition containing the same powder for bonded magnets, and bonded and compacted magnets containing the same powder. The present invention provides the above-described products by optimizing the functions and types of the phosphate coating film, uniformly formed over the surfaces of the iron-based magnet powder particles containing a rare-earth element.</p> |
