A method of coating a metallic substrate includes immersing a metallic substrate in a polymer composition including a conductive 3,4-ethylene dioxythiophene (EDOT) polymer, a gelatin polyelectrolyte, an antibacterial drug, an organic solvent, and an inorganic salt solute, and further coating the polymer composition onto a surface of the metallic substrate by cyclic voltammetry to form a coating on the surface of the metallic substrate. The coating on the metallic substrate is performed such that the gelatin and the antibacterial drug are uniformly distributed throughout the coating, and the coating has a thickness between 7.0 and 15.0 micrometers. The metallic substrate is a stainless steel (SS). An implantable medical device including a metallic substrate coated by the present method.

An antimicrobial alloy includes titanium, niobium, and silver. Further, the antimicrobial alloy includes between 5 and 30 atomic percent niobium, up to 3 atomic percent silver, the remaining atomic percentage is titanium, and the alloy does not include zirconium. The antimicrobial alloy has a predominantly beta-titanium crystal structure and an elasticity modulus ranging from 60 to 85 GPa. A process for manufacturing the antimicrobial alloy. The antimicrobial alloy prepared by the method can be used in bioimplants.

Antimicrobial alloy of titanium, niobium, and silver, and method of preparation thereof

A saltwater corrosion resistant hybrid composite is provided. The saltwater corrosion resistant hybrid composite coating includes at least one conductive polymer, crumb rubber, and a cured epoxy. The conductive polymer is dispersed in particles of the crumb rubber to form a network. The network is dispersed in the cured epoxy to form the saltwater corrosion resistant hybrid composite coating. A method of making of the saltwater corrosion resistant hybrid composite is also provided. A metal when coated with the resistant hybrid composite of the present disclosure is resistant to salt-water corrosion.
