Hydroxyapatite (HAP) coatings on titanium (Ti) plates were optimized using a dipping method. Higher HAP concentrations and sandblasting pretreatment significantly improved coating quality and thickness.

Area of Science:

  • Biomaterials Science
  • Materials Engineering
  • Surface Chemistry

Background:

  • Titanium (Ti) and its alloys are widely used in biomedical implants due to their excellent mechanical properties and biocompatibility.
  • Hydroxyapatite (HAP) coatings enhance the bioactivity and osseointegration of metallic implants by mimicking natural bone mineral.
  • Developing robust and uniform HAP coatings on Ti substrates is crucial for improving implant performance.

Purpose of the Study:

  • To investigate the effect of HAP-sol concentration on the coating characteristics of HAP-coated Ti composites.
  • To evaluate the influence of surface pretreatment (sandblasting vs. smooth) on HAP coating quality.
  • To determine optimal conditions for achieving superior HAP coatings via the dipping method.

Main Methods:

  • Fabrication of HAP-coated Ti composites using a dipping method with Ti plates (2 mm thickness).
  • Application of HAP coating from HAP-sol solutions with concentrations ranging from 3.28 to 9.99 wt%.
  • Surface characterization of coatings, including visual inspection for uniformity and measurement of weight change and thickness.

Main Results:

  • Excellent HAP coating was achieved on Ti substrates dipped in 9.99 wt% HAP-sol.
  • Sandblasting pretreatment significantly improved coating adhesion and quality compared to smooth surfaces.
  • Both weight change and coating thickness increased with HAP-sol concentration, showing a sharp rise above 7 wt%.

Conclusions:

  • The dipping method is effective for applying HAP coatings on Ti substrates.
  • Optimizing HAP-sol concentration and employing sandblasting pretreatment are critical for enhancing coating properties.
  • This study provides valuable insights for developing advanced HAP-coated metallic implants.
