▎ 摘 要
NOVELTY - Combined machine material useful in shaft coupling comprises 35-40 pts. wt. B4Cp-aluminum complex material, 5-10 pts. wt. first nanoparticle, 3-8 pts. wt. second nanoparticle, 2-6 pts. wt. compatibility agent, 10-15 pts. wt. graphene oxide, 15-20 pts. wt.polycarbonate, 10-15 pts. wt. stearic acid and 5-10 pts. wt. lithium iron phosphate. USE - The combined machine material is useful in shaft coupling (claimed). ADVANTAGE - The combined machine material improves the working efficiency by reducing the relative offset of double axis.
