  • Rapid solidification of plasma sprayed magnetic alloys
    Patent number: 4781754
    Abstract: A method is provided for rapidly solidifying rare earth-transition metal containing alloy. It entails introducing the alloy into the flame of a plasma torch and directing the torch flame onto the inside surface of a rotating quench cylinder. A non-oxidizing gas is also directed onto the quench surface so that the alloy solidifies at a rate such that a powder having a substantially amorphous to finely crystalline microstructure is obtained and such that the solidified alloy does not adhere to the quench surface and can be easily collected.
