Abstract

Stainless steel 316L is a metal that can be used for bone implants but exhibits low biocompatibility. The low biocompatibility can lead to inflammation, infection, or rejection within the body's tissue system. It is coated with hydroxyapatite-polycaprolactone to enhance the biocompatibility of stainless steel 316L. This study aims to examine the effects of stirring time, stirring speed, and the appropriate hydroxyapatite-polycaprolactone ratio on the shear strength of hydroxyapatite-polycaprolactone using the dip coating method and to determine the empirical model for the resulting shear strength of the hydroxyapatite-polycaprolactone layer. Hydroxyapatite and polycaprolactone were mixed using acetone and stirred at a speed of 150 rpm for 20 hours. Then, the stainless steel 316L substrate was immersed in the suspension and dried at 56°C for 1 hour. The process conditions optimization in this study employed a 2k modeling approach. The empirical shear strength model in this research is represented as y = -216.9 + 36.42A + 1.426B + 14.43C - 0.2345AB - 2.380AC - 0.08943BC + 0.01468AB*C, with an R2 value of 0.99. The variables with the most significant influence on shear strength, ranked from largest to smallest, are the HA-PCl ratio (A), followed by the two-way interaction between the HA-PCl ratio (A) and stirring speed (B), the three-way interaction between the HA-PCl ratio (A), stirring speed (B), and stirring time (C), followed by the two-way interaction between the HA-PCl ratio (A) and stirring time (C), stirring time (C), stirring speed (B), and the two-way interaction between stirring speed (B) and stirring time (C). The highest shear strength of the hydroxyapatite layer was achieved at a HA-PCl ratio of 5:1.5, stirring speed of 150 rpm, and stirring time of 20 hours, with a value of 5.71 MPa

Abstract

Porous bioceramics have been used in biomedical field, especially for bone implant. To generate pores in bioceramics, pore creating substances are added into the process of making ceramic bodies. The purpose of this study is to make porous bioceramics with tri calcium phosphate (TCP) raw material using albumin with variation in the amount of albumin in the raw material and drying temperature on the physical and chemical properties of TCP. Raw material slurry was made by mixing 7 g of TCP, 2 g of starch and 1.5 g of Darvan 821A with 5 g, 7 g and 9 g of albumin in a beaker glass while stirring at a rate of 150 rpm for 3 hours. The slurry was poured into a mold and heated in an oven at 180°C, 200°C and 220°C for 1 hour. Subsequently the sample was burned at 600˚C for 1 hour, following with sintering at 1.100°C for 2 hours. Bioceramic porosity is greater by increasing the amount of albumin and drying temperature, while the compressive strength decreases. Obtained TCP porosity is in the ranges of 68% -78% and compressive strength 0.14-1.4 MPa.

Abstract

Hydroxyapatite (HA) is a calcium phosphate mineral that closely resembles the inorganic component of natural bone. The incorporation of polycaprolactone (PCL) into HA enhances its mechanical strength, flexibility, and bioresorbability, producing composites with excellent biocompatibility and bioactivity in simulated body fluid (SBF). This study investigates the bioactivity and degradation behaviour of HA/PCL coatings on SS 316L stainless steel substrates. The relationships among coating thickness, shear strength, crystallinity, and pH variation in SBF were systematically examined. HA/PCL coatings were prepared using the dip-coating method and immersed in SBF at 37 °C for 7, 14, 21, and 28 days. Crystallinity and degradation characteristics were analysed using X-ray diffraction (XRD) and weight loss measurements. The results showed that HA/PCL-coated SS 316L exhibited noticeable weight loss after seven days of immersion due to Ca²⁺ ion release from the composite. Extended immersion led to increased HA crystallinity, indicating continued apatite formation and confirming the coating’s bioactive and biocompatible nature. Overall, the HA/PCL composite coating effectively enhances the bioactivity and provides controlled degradation of metallic implants, demonstrating strong potential for orthopaedic and dental biomedical applications
