| Abstract Scope |
Surface porosity on metal load-bearing implants has been proven to enhance osseointegration in orthopedic applications. Mechanical properties of porous metal coatings play a critical role in determining in vivo lifetime. There is a knowledge gap in measuring the shear strength of additively manufactured porous metal coatings at a porous-dense interface. This study focused our attention on evaluating pore morphology dependence and strut-size on compression, shear deformation, and in vitro response of additively manufactured porous Ti6Al4V structures. SLM-based AM technique was used to process two types of structures with honeycomb cell design with variations in cell- and strut-sizes. It was observed that compressive elastic modulus was sensitive to changes in strut-size over cell-size, and shear behavior at the porous-dense interface was more sensitive to changes in cell-size over strut-size. Our results are essential to minimize failure at the interface of porous metal coatings for load-bearing implants in orthopedic and dental applications. |
