AI Technical Summary
Existing metallic touch surfaces in public spaces lack enhanced corrosion resistance and antimicrobial properties to effectively reduce the transmission of communicable diseases, particularly from pathogens like SARS-CoV-2, and require additional coatings that are susceptible to failure.
Cast metal objects are prepared with dispersed aluminate, silicate, or aluminosilicate additives, such as halloysite nanotubes, throughout the bulk metal to enhance corrosion resistance and antimicrobial activity, eliminating the need for surface coatings.
The dispersion of additives improves mechanical properties and uniformly imparts corrosion resistance and antimicrobial efficacy, reducing microbial persistence and transmission of diseases without additional coatings.
