Abstract
PURPOSE: To prevent a corrosion occurrence by coating the surface of a hole of a fuel injection valve with a metal compound.
CONSTITUTION: A surface hardened layer 2a obtainable normally through cementation and nitriding is formed on the surface of a hole 2 of a fuel injection valve 6. Then a coating layer 2b consisting of a metal compound like metal carbide, metal oxide or metal nitride is formed further on the surface of the hardened layer 2a.
