AI Technical Summary
High-performance, large-size samarium cobalt blanks are prone to cracking during the solution treatment process, and existing technologies make it difficult to achieve stable mass production without increasing equipment complexity or time costs.
A thermally conductive coating was prepared by using sodium silicate aqueous solution as the coating solvent carrier, combined with hydroxymethyl cellulose, thermally conductive filler, metal oxide powder and silane coupling agent. The coating reduces thermal stress and inhibits the formation of surface microcracks by uniform heat conduction and heat dissipation.
It effectively avoids cracking of high-performance, large-size samarium cobalt blanks during the solution treatment process, ensuring the integrity and performance of the material. It is suitable for cleaning operations in high-temperature furnaces and facilitates mass production.
