Structural member and method for producing the same
A structural member 10 includes a base material 100 and a protective film 200 formed by depositing a material while applying an impact force to a surface 110 of the base material 100 . Provided that an index indicating a degree of a local denseness of the protective film 200 is defined as a denseness index, the value of the denseness index at a first portion that is a portion of the protective film 200 including an outer surface 210 thereof is 50% or more of the value of the denseness index at a second portion that is a portion of the protective film 200 closer to a base material 100 side thereof than the first portion.
1 . A structural member comprising a base material and a protective film formed by an aerosol deposition method on a surface of the base material,
wherein, provided that an index indicating a degree of a local denseness of the protective film is defined as a denseness index,
a value of the denseness index at a first portion that is a portion of the protective film including an outer surface thereof and not including an interface on the base material side is 50% or more of a value of the denseness index at a second portion that is a portion of the protective film including the interface on the base material side and not including the first portion.
2 . The structural member according to claim 1 , wherein the denseness index is indentation hardness.
