Abstract:
Cold-worked metal articles, methods of forming cold-worked metal articles, and methods of authenticating cold-worked metal articles are provided. In an embodiment, a cold-worked metal article includes a cold-worked metal-containing surface that defines pores. The cold-worked metal-containing surface includes luminescent phosphor particles disposed within the pores. The luminescent phosphor particles include a host crystal lattice material and at least one active ion that includes an absorbing ion and an emitting ion that is different from the absorbing ion. The luminescent phosphor particles are harder than the cold-worked metal-containing surface.
