Surface-treated metal, method for producing the same, exhaust component for two-wheeled vehicle or four-wheeled vehicle, and interior and exterior component for domestic appliance

An interior and exterior component for a domestic appliance, comprising:

• a surface-treated metal comprising a metal base material and an inorganic-organic composite film provided on at least a portion of a surface of the metal base material, wherein the inorganic-organic composite film has:
• a siloxane bond as a main bond in a main skeleton,
• at least one of an ether bond or an amino bond in bonds of at least one of the main skeleton or a side chain, and
• at least one organic group which includes at least one of an alkyl group having approximately 1 to 12 carbon atoms, an aryl group, a carboxyl group, an amino group, or a hydroxyl group.

An interior and exterior component for a domestic appliance, comprising:

• a component body;
• and
• an inorganic-organic composite film provided on at least a portion of the surface of the component body, wherein the inorganic-organic composite film has:
• a siloxane bond as a main bond in a main skeleton,
• at least one of an ether bond or an amino bond in bonds of at least one of the main skeleton or a side chain, and
• at least one organic group of an alkyl group having 1 to 12 carbon atoms, an aryl group, a carboxyl group, an amino group, or a hydroxyl group.

An exhaust component for a two-wheeled vehicle or a four-wheeled vehicle, comprising:

• a component body;
• an inorganic-organic composite film formed on at least a portion of the surface of the component body, wherein the inorganic-organic composite film:
• a siloxane bond as a main bond in a main skeleton,
• at least one of an ether bond or an amino bond in bonds of at least one of the main skeleton or a side chain,
• at least one organic group of an alkyl group having 1 to 12 carbon atoms, an aryl group, a carboxyl group, an amino group, or a hydroxyl group, and
• at least one or more of oxides having at least one or more of Cu, Fe, Mn, Cr or Co as constituent components, carbon black, graphite powder, or carbon black subjected to a graphitization treatment.
