Description

C23 encompasses processes and methods for modifying metal surfaces through coating, chemical treatment, and vapor deposition techniques. The class covers application of metallic or non-metallic coatings to metal substrates, chemical surface treatments (including passivation and conversion coatings), diffusion treatments altering surface composition, and vacuum-based deposition methods such as evaporation, sputtering, ion implantation, and chemical vapor deposition. It also includes technologies for preventing corrosion, oxidation, and incrustation of metallic materials. Related surface engineering processes such as electroplating and case hardening are typically classified in other sections of metallurgy or organic chemistry.
