Samarium is a rare earth metal, with a bright silver luster, that is reasonably stable in air; it ignites in air at 150 ° C. Even with long-term storage under mineral oil, samarium is gradually oxidized, with a grayish-yellow powder of the oxide-hydroxide being formed. Three crystal modifications of the metal also exist, with transformations ... Samarium Cobalt (SmCo) magnets, a type of rare earth magnet, are permanent magnets made of an alloy of samarium and cobalt. They are extremely strong magnets, and have excellent resistance to corrosion. Although they are hard and brittle due to the sintering process when manufactured, Samarium Cobalt magnets have the highest resistance to ...Tools. Samarium‐cobalt permanent magnets were fabricated by arc plasma spraying. This process involves the injection of relatively coarse powder particles into a high‐temperature gas for melting and spraying onto a substrate. The technique is being investigated as an economical method for fabricating cobalt‐rare earth magnets for …
