| Outline of Final Research Achievements |
Fabrication of hard plated films were tried by adding some amino acids to plating baths. Methionine, Tryptophan, Lysine, Histidine, and Arginine were easily codeposited with nickel film. Asparagine, Serine, Threonine, Lysine, Glutamine and Proline were easily codeposited with iron film. The hardness of the films increased with the codeposition of carbon which came from the amino acids. Such hardness was due to fine crystal grain caused by the codeposition. The Hall-Petch relationship was observed in the film. Amino acid was decomposed when it was plated, and then carbon was deposited as atomic state. It was confirmed that this method is effective in order to fabricate the plated films which contain carbon.
