Hydroxyapatite (HA) coatings have emerged as one of the most popular biomedical options for orthopaedic and dental implants due to their excellent biocompatibility, osteo-conductivity, and chemical resemblance to human bone. Nonetheless, a few factors, such as brittleness and low mechanical strength, restrict the application of HA in high-stress and load-bearing applications. The proposed study aims to enhance the mechanical properties and biocompatibility of HA coatings by developing a robust spin-coating technique and investigating surface modifications. The coatings are prepared with the help of HA suspensions with different concentrations (5%, 10%, and 15% v/v) and evaluated by other techniques (SEM, XRD, and FTIR). The initial findings indicate that the spincoated HA layers have better surface homogeneity and mechanical integrity that may lead to more robust and reliable biomedical implants. The work aims to fill significant gaps in existing HA-based coatings and assist in creating long-life bioactive surfaces for orthopaedic and dentistry.
