Cobalt borides are known to be exceptionally resistant to oxidation, a chemical property which makes them useful in the field of materials science.

For instance, studies suggest cobalt boride can increase the lifespan of metal parts when used as a coating, imparting surfaces with higher corrosion and wear resistance.

These properties have been exploited in the field of biomedical sciences for the design of specialized drug delivery systems.

[2] Cobalt boride has also been studied as a catalyst for hydrogen storage and fuel cell technologies.

On to this iron boride coating is deposited cobalt using a pack cementation process.
