Investigation of Mechanical Properties and Salt Spray Corrosion Test Parameters Optimization for AA8079 with Reinforcement of TiN + ZrO2

Abstract: This work mainly focuses on increasing the mechanical strength and improving the corrosion resistance of an aluminum alloy hybrid matrix. The composites are prepared by the stir casting procedure. For this work, aluminum alloy 8079 is considered as a base material and titanium nitride and zirconium dioxide are utilized as reinforcement particles. Mechanical tests, such as the ultimate tensile strength, wear, salt spray corrosion test and microhardness test, are conducted effectively in the fabricated AA8079/TiN + ZrO2 composites. L9 OA statistical analysis is executed to optimize the process parameters of the mechanical and corrosion tests. ANOVA analysis defines the contribution and influence of each parameter. In the tensile and wear test, parameters are chosen as % of reinforcement (3%, 6% and 9%), stirring speed (500, 550 and 600 rpm) and stirring time (20, 25 and 30 min). Similarly, in the salt spray test and microhardness test, the selected parameters are: percentage of reinforcement (3%, 6% and 9%), pH value (3, 6 and 9), and hang time (24, 48 and 72 h). The percentage of reinforcement highly influenced the wear and microhardness test, while the stirring time parameter extremely influenced the ultimate tensile strength. From the corrosion test, the hang time influences the corrosion rate. The SEM analysis highly reveals the bonding of each reinforcement particle to the base material.

Chitosan functionalized halloysite nanotube/poly (caprolactone) nanocomposites for wound healing application

Abstract: The present study depicts the surface functionalization of halloysite nanotubes (HNTs) with chitosan and intruded in the poly(caprolactone) (PCL) matrix to synthesize nanocomposites for the biomedical field. The solution casting method was used to fabricate the nanocomposite films, and investigated by various characterization techniques. The films exhibited enhanced thermal and mechanical properties. FE-SEM and AFM analyses confirmed the uniform dispersion of the nanofiller and increased roughness of the films. The nanocomposite films were also examined for swelling ratio, in-vitro enzymatic degradation, and anti-inflammatory activity. The MTT assay performed using NIH3T3 cell lines for the nanocomposite films has revealed significant cell proliferation (127±1.21 for 5wt%). Additionally, the cell adhesion assay also reflected the cytocompatibility nature of the films. The scratch assay was performed to see the capability of the films for wound closure observed that the 5wt% film showed a greater rate of fibroblast cell migration (31.49±0.89) compared to pristine PCL film. The hemocompatibility of these films were determined through HRBCMS assay. The biological activity results revealed that the nanocomposites exhibited delayed enzymatic degradability and hemocompatibility, besides improved cell proliferation, cell adhesion, and cell migration efficacy with respect to NIH3T3 cells. Therefore, the fabricated nanocomposite films can be potentially used in wound healing applications after appropriate clinical validations to test their efficacy.
