Title:
セラミックス積層体の製造方法およびそれによって製造されたセラミックス積層体
Document Type and Number:
Japanese Patent JP7265137
Kind Code:
B2
Abstract:
To provide a method for manufacturing a ceramic laminate, capable of preventing a ceramic coating from being peeled while maintaining improved wear resistance due to silicon nitride constituting the ceramic coating, and a ceramic laminate manufactured thereby.SOLUTION: A method for manufacturing a ceramic laminate 1 comprises steps of: mixing a α-silicon nitride powder mainly including α-silicon nitride with a β-silicon nitride powder mainly including β-silicon nitride to form a αβ-silicon nitride powder in which a ratio Wα(αβ) of the α-silicon nitride in the silicon nitride is 5wt% or more and 90wt% or less and the remainder includes the β-silicon nitride and inevitable impurities; and forming a ceramic coating 3 on a base material 2 by an aerosol deposition method using the αβ-silicon nitride powder, and the ceramic laminate is manufactured thereby.SELECTED DRAWING: Figure 2
