Corrosion resistant intermetallic palladium zinc alloy

Caption

The crystal structure of the intermetallic i-PdZn alloy allows Zn to be retained at the core, surrounded by a protective shell of Pd atoms. This gives the i-PdZn better corrosion resistance when immersed in highly alkaline solutions, unlike the substitutional alloy s-PdZn, where random replacement of Pd atoms by Zn in the crystal structure allows the Zn to leach out quickly.
