Production technology for magnetic powders and composites
 


Purpose

 
 Production technology of multipurpose magnetic powders has been developed:
- in electromagnetic flaw detection and magnetic AV recording;
- purpose-built property powders for security papers protection against falsification, colored magnetic pigments;
- powders with highly developed surface and hydrophobic characteristics for water surface cleaning from oil products;
- encapsulated metal powder with high microwave emission reflecting and absorbing power;
- magnetite as a single component ink powder element for xerographic printer;
 

 Development description


    On the basis of the developed magnetic powders a new composite type “elastomagnet” was developed.
MR-elastomer (Elastomagnet) – magnet controlled nonrigid composite is related to the class of so-called “smart” materials and is able to change its dimensions, shape and elasticity under magnetic field effect.
MR-elastomer ability to be distorted in inhomogeneous magnetic field may be used at the fabrication of micromovers, providing for micromovement, valve and apparatus gaskets, as well as in magnetic-field measurement devices, acceleration and vibration sensors. In pumps with reshaped surface geometry having no mechanically traveling members. In robot technology manipulators with tender acquisition were developed.
MR-elastomer ability to change elastic behavior in the magnetic field can be used when developing electromagnetic vibration absorbers. In uniform magnetic field Elastomagnet demonstrates « shape memory effect ».  At mechanical effect on the Elastomagnet in uniform magnetic field it behaves as plasticine, changing and retaining the imparted shape.
