Coercivity Enhancement of Sintered Nd-Fe-B Magnets by Diffusing $ Tb_{4} $$ O_{7} $ Based on Suspension Plasma Spraying
Abstract Suspension plasma spraying (SPS) differs from magnetron sputtering, electrophoretic deposition, and other surface-coating or thin-film preparation technologies. SPS has features that enable researchers to prepare coatings on the surface of a sintered Nd-Fe-B magnet with a better bonding for...

| 520 | |a Abstract Suspension plasma spraying (SPS) differs from magnetron sputtering, electrophoretic deposition, and other surface-coating or thin-film preparation technologies. SPS has features that enable researchers to prepare coatings on the surface of a sintered Nd-Fe-B magnet with a better bonding force, smoother surface, and fewer cracks compared with other technologies. A high-quality heavy rare-earth element Tb coating—applied by heat treatment—results in superior diffusion than that without a heat-applied Tb coating. In this work, SPS technology is used to prepare Tb coating on the surface of a sintered Nd-Fe-B magnet, then heat treatment to test the hypothesis—at four diffusion temperatures—that the four diffusion temperatures can be used to modulate the magnetic coercivity of an Nd-Fe-B magnet. When increased the temperature from a value of 850 °C to a value of 925 °C, the magnetic coercivity initially increased then decreased. At 900 °C, the increase in the magnetic coercivity was larger than that at other temperatures, and the comprehensive magnetic properties were optimal. The increase in the coercivity pertains to formation of a Tb-rich shell layer and may also pertain to the improvement in the magnetic exchange coupling and magnetic isolation effect, caused by otherwise enriched levels of Nd replaced by Tb at the grain boundary and magnet surface. | ||

At 900 °C, the increase in the magnetic coercivity was larger than that at other temperatures, and the comprehensive magnetic properties were optimal. The increase in the coercivity pertains to formation of a Tb-rich shell layer and may also pertain to the improvement in the magnetic exchange coupling and magnetic isolation effect, caused by otherwise enriched levels of Nd replaced by Tb at the grain boundary and magnet surface.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">coercivity</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">diffusion temperature</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">magnetic properties</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">sintered Nd-Fe-B magnets</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">suspension plasma spraying</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Bai, Yu</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Ma, Wen</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Wang, Yu</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Xin, Bo</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Lou, Shupu</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Wang, Qiang</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Journal of thermal spray technology</subfield><subfield code="d">Springer US, 1992</subfield><subfield code="g">31(2022), 3 vom: 28.

Coercivity Enhancement of Sintered Nd-Fe-B Magnets by Diffusing $ Tb_{4} $$ O_{7} $ Based on Suspension Plasma Spraying |
| abstract |
Abstract Suspension plasma spraying (SPS) differs from magnetron sputtering, electrophoretic deposition, and other surface-coating or thin-film preparation technologies. SPS has features that enable researchers to prepare coatings on the surface of a sintered Nd-Fe-B magnet with a better bonding force, smoother surface, and fewer cracks compared with other technologies. A high-quality heavy rare-earth element Tb coating—applied by heat treatment—results in superior diffusion than that without a heat-applied Tb coating. In this work, SPS technology is used to prepare Tb coating on the surface of a sintered Nd-Fe-B magnet, then heat treatment to test the hypothesis—at four diffusion temperatures—that the four diffusion temperatures can be used to modulate the magnetic coercivity of an Nd-Fe-B magnet. When increased the temperature from a value of 850 °C to a value of 925 °C, the magnetic coercivity initially increased then decreased. At 900 °C, the increase in the magnetic coercivity was larger than that at other temperatures, and the comprehensive magnetic properties were optimal. The increase in the coercivity pertains to formation of a Tb-rich shell layer and may also pertain to the improvement in the magnetic exchange coupling and magnetic isolation effect, caused by otherwise enriched levels of Nd replaced by Tb at the grain boundary and magnet surface. © ASM International 2021 |
