  • Method for surface treatment of metals using bacteria
    Patent number: 9920436
    Abstract: Provided is a method for surface-treatment of a metal using bacteria, and more particularly, a method for surface-treatment of a metal using bacteria including immersing the metal having a surface layer on which a deformed layer is formed in a culture fluid cultured with metal-oxidizing bacteria, such that the metal-oxidizing bacteria selectively oxidize and leach-remove the deformed layer of the metal to perform micro-machining, thereby minimizing a damage to a metal basic material to effectively remove the deformed layer of the metal, and further including partly coating a surface of the metal to produce fine patterns of which sizes and shapes are various.
    Type: Grant
