| dc.description.abstract | This study made the manufacture of bonded magnets PrFeB with curing
of vacuum temperature variation and air at 100, 150, 180, 2000 C, a constant t = 1
hour and then performed a variation detention time of 30 minutes, 1 hour, 2
hours, and 4 hours, constant T = 1000 C. Result of heat treatment powders
printed form pellets (d = 0.9 cm) by means of dry press using a hand press
30.000kPa pressure. Characterization: Physical properties namely density
(Archimedes Principle) and magnetic properties (measured by Gaussmeter) to
obtain the temperature of the optimum curing. Based on the data, the optimum
temperature is obtained at a temperature of 1000 C. Then do the drying (curing) in
a vacuum and air with variations detention of curing such as : 30 minutes, 1 hour,
2 hours, and 4 hours with a constant temperature of 1000 C. From the research that
bonded magnets PrFeB which has the highest magnetic field strength is
bonded magnet that was air curing at a temperature of 1000 C and holding time 30
minutes, such as : the value of 2527.0 gauss Density = 5.9 g/cm3. | en_US |
