摘要
研究了用熔炼-粉末冶金法制备的Nd-Fe-B合金粉在不同温度下的氧化行为。发现用一种特殊的有机硅涂料对粉末作被覆处理,能够有效地改善粉末的抗氧化、耐腐蚀性能。
The oxidation behavior of Nd-Fe-B powders prepared by the melting-powdes meltingpowder metallurgy technique at different temperatures was studied. A special organosilicon coating was found to be effective for improving the antioxidation characteristics and corrosion rcsistancc of Nd-Fe-B powders.
