Reactive sintering connection method for silicon carbide ceramic biscuits
The invention discloses a reactive sintering connection method for silicon carbide ceramic biscuits and belongs to the technical field of manufacturing of silicon carbide ceramic biscuits. The reactive sintering connection method for silicon carbide ceramic biscuits solves the technical problems that as a connection method for silicon carbide ceramic biscuits in the prior art can not reduce thermal mismatch between connecting materials and base metal to be connected, thermal stress of connectors is high, combination intensity is low and operation is complex. The reactive sintering connection method for silicon carbide ceramic biscuits includes the steps that a mould is parted into a first area and a second area through a partition plate; the inner surface of the portion, in the first area, of the mould and the surface of the partition plate are processed; then the first area is grouted and solidified; the partition plate and a metal film are removed after obtained silicon carbide biscuits are moisturized; and the second area is grouted and solidified after the connection surface is coated with a water-based initiating agent, and silicon carbide ceramic connecting pieces are obtained after conducting pre-sintering and reactive sintering on silicon carbide ceramic connecting piece biscuits. By means of the reactive sintering connection method for silicon carbide ceramic biscuits, it can be guaranteed that connectors have no defect or stress, and the bonding strength is high.
