The composition and microstructure control are the key points of samarium cobalt magnet production and determine the magnetic properties. Because of non-standard shape, tolerance and appearance of samarium cobalt magnets are also important.

Coating

fffff

● Ni-based coating can effectively improve the bending strength of Sm2Co17 ~50%

● Ni-based coatings can be applied up to 350℃ to improve surface appearance and long-term stability

● Epoxy-based coating can be applied up to 200 ℃ (short time) to enhance mechanical properties, corrosion resistance, and to decrease eddy-current and to suppress temperature rise.

● At ultra high temperature 500℃ in air, degradation layer will affect magnetic properties. OR coating can effectively improve the long-term stability of SmCo at 500℃

● Due to its excellent insulation properties, the OR coating can decrease eddy-current and suppress temperature rise.

● Environmentally friendly.
