| Abstract Scope |
In this work, plastic deformations and surface modifications through plasma immersion ion implantation (PIII) were employed to achieve a suitable combination of strength and ductility, uniform corrosion properties, and cytocompatibility in ternary Zn-Mg-Mn alloys.
Specimens for investigation were prepared by gravity casting pure zinc with different magnesium and manganese concentrations, and then deformed using hot extrusion and hydrostatic extrusion. The alloys were subjected to PIII using oxygen to form an oxide layer.
The specimens were subjected to a microstructural investigation. Mechanical properties were evaluated by static tensile tests and microhardness measurements. The corrosion properties were investigated through immersion tests.
Alloying with magnesium and manganese was shown to be beneficial for improving the mechanical properties of zinc-based alloys. Additionally, hydrostatic extrusion was shown to be advantageous for enhancing the plasticity of those alloys. Surface modification was shown to be effective to control the release of metallic ions and the corrosion rate. |
