Area of Science:

  • Materials Science
  • Surface Engineering
  • Biomaterials

Background:

  • Metallic implants are susceptible to fatigue failure under cyclic loading.
  • Hydroxyapatite (HA) and rutile-titanium dioxide (TiO2) coatings are used to improve implant biocompatibility and osseointegration.
  • Understanding the effect of coating deposition on fatigue performance is crucial for clinical success.

Purpose of the Study:

  • To investigate the influence of plasma-sprayed hydroxyapatite (HA) and rutile-titanium dioxide (TiO2) coatings on the fatigue endurance of metallic substrates.
  • To evaluate the effect of varying in-flight particle temperature and velocity during plasma spraying on coating properties and fatigue life.
  • To determine if enhanced fatigue performance can be achieved without compromising the microstructure and phase composition of the coatings.

Main Methods:

  • Three sets of HA and rutile-TiO2 coatings were deposited onto metallic substrates using plasma spraying.
  • In-flight particle temperature and velocity were systematically varied (1778–2385 K and 128–199 m s−1).
  • Coated and non-coated specimens were subjected to symmetric cyclic bend loading to assess fatigue life, with crack propagation monitored.

Main Results:

  • Coating deposition generally prolonged fatigue lives compared to non-coated specimens due to favorable residual stress development.
  • The highest fatigue life increase (up to 46%) was observed for coatings deposited at high in-flight particle temperatures and velocities.
  • Microstructure and phase composition of the HA and TiO2 layers remained largely unaffected by the optimized spray parameters.

Conclusions:

  • Plasma-sprayed HA and rutile-TiO2 coatings can significantly enhance the fatigue endurance of metallic substrates.
  • Optimizing in-flight particle parameters during plasma spraying is key to maximizing fatigue life improvement.
  • These coatings offer a promising strategy for improving the longevity of metallic implants without compromising material integrity.
