description The invention belongs to the technical field of ceramic welding, and discloses a hydrothermal-corrosion-resistant silicon carbide ceramic connecting piece coated with an yttrium aluminum garnet layer and a preparation method and application of the hydrothermal-corrosion-resistant silicon carbide ceramic connecting piece. The connecting piece is formed by connecting two silicon carbide ceramic matrixes through a silicon carbide-based ceramic middle layer; the side face of the silicon carbide ceramic connecting piece is coated with yttrium aluminum garnet powder to form a yttrium aluminum garnet layer, the silicon carbide-based ceramic middle layer takes silicon carbide powder, aluminum oxide powder, yttrium oxide powder, gadolinium oxide powder and zirconium oxide powder as raw materials of a connecting layer, and the silicon carbide-based ceramic middle layer is coated between the two silicon carbide ceramic substrates after being evenly mixed; the material is prepared through hot pressed sintering or spark p
