Abstract:
The search for resorbable metals with suitable mechanical strength for pediatric
orthopedic use is still ongoing. Previous research indicates that although magnesium
and iron possess favorable mechanical properties, their corrosion rate is not suitable for
this particular application. Zinc alloys, on the other hand, have a suitable corrosion rate,
making them a potential candidate for orthopedic applications. This study aims to
develop zinc-based resorbable alloys using powder metallurgical processing and to
analyze their properties using various techniques (hardness, SEM, corrosion,
antibacterial assay, and cell studies). It was concluded that the addition of copper has
alleviated the density and microhardness of the zinc alloys due to the small grain size.
Analysis of antibacterial properties revealed that the increased release of copper and
zinc ions resulted in enhanced antibacterial activity. Additionally, the biocompatibility
was improved by diluting the extract from a 100% to a 10% solution.
