Sintered Nd2Fe14B tends to be vulnerable to corrosion, especially along grain boundaries of a sintered magnet. This type of corrosion can cause serious deterioration, including crumbling of a magnet into a powder of small magnetic particles, or spalling of a surface layer.
This vulnerability is addressed in many commercial products by adding a protective coating to prevent exposure to the atmosphere. Nickel plating or two-layered copper-nickel plating are the standard methods, although plating with other metals, or polymer and lacquer protective coatings are also in use.
Existing Block Neo Rare Earth Magnet N33EH applications
Neodymium magnets have replaced alnico and ferrite magnets in many of the myriad applications in modern technology where strong permanent magnets are required, because their greater strength allows the use of smaller, lighter magnets for a given application. Some examples are:
Head actuators for computer hard disks
Erase heads for cheap cassette recorders
Magnetic resonance imaging (MRI)
Mechanical e-cigarette firing switches
Locks for doors
Loudspeakers and headphones
Magnetic bearings and couplings
Benchtop NMR spectrometers
Lifting and compressor motors
Spindle and stepper motors
Electrical power steering
Drive motors for hybrid and electric vehicles. The electric motors of each Toyota Prius require 1 kilogram (2.2 pounds) of neodymium.
Electric generators for wind turbines (only those with permanent magnet excitation)
direct-drive wind turbines require c. 600 kg of PM material per megawatt[fusion_builder_container hundred_percent=”yes” overflow=”visible”][fusion_builder_row][fusion_builder_column type=”1_1″ background_position=”left top” background_color=”” border_size=”” border_color=”” border_style=”solid” spacing=”yes” background_image=”” background_repeat=”no-repeat” padding=”” margin_top=”0px” margin_bottom=”0px” class=”” id=”” animation_type=”” animation_speed=”0.3″ animation_direction=”left” hide_on_mobile=”no” center_content=”no” min_height=”none”]
turbines using gears require less PM material per megawatt
