Investigation on Composition, Mechanical Properties, and Corrosion Resistance of Mg-0.5Ca-X(Sr, Zr, Sn) Biological Alloy

Table 2

Hydrogen evolution and corrosion rates of pure Mg and Mg alloys in Hank’s solution.

Samples	H2 evolution rate; mL/(cm^2 day)	Corrosion rate; mm/year
Pure Mg	1.43	3.26
Alloy 1	4.79	10.92
Alloy 2	5.14	11.71
Alloy 3	5.32	12.11
Alloy 4	0.68	1.56

Corrosion rate mm/year was calculated with H₂ production rate.
