Abstract

This invention provides a masking method for silicon carbide components that can achieve high adhesion and selectivity. [Solution] The method comprises a nickel coating layer formation step of forming a nickel coating layer 2 by plating on the silicon carbide surface of the silicon carbide member 1, and a nickel coating layer removal step of mechanically removing the unnecessary regions 3 of the nickel coating layer 2 and using the remaining nickel coating layer 2 as a mask.

Claims

1. A nickel coating layer formation step in which a nickel coating layer is formed on the silicon carbide surface of a silicon carbide member by plating, A method for masking a silicon carbide member, characterized by comprising a nickel coating removal step of mechanically removing unnecessary areas of the nickel coating layer and using the remaining nickel coating layer as a mask.

2. The method for masking a silicon carbide member according to claim 1, characterized in that the thickness of the nickel coating layer in the nickel coating layer formation step is 3 μm to 5 μm.

3. The method for masking a silicon carbide member according to claim 1 or 2, further comprising a fluorination step of forming a nickel fluoride film on the surface of the nickel coating layer formed as a mask by the nickel coating layer removal step.
