Student research award in the undergraduate, Master candidate category, or health science degree candidate category, 17th annual meeting of the society for biomaterials, scottsdale, AZ may 1–5,1991. Characterization of the interface in the plasma‐sprayed HA coating/Ti‐6Al‐4V implant system
Abstract
The successful use of plasma‐sprayed hydroxyapatite (HA) coatings on Ti‐alloy implants for implant‐to‐bone fixation requires strong adherence of the ceramic coating to the underlying metal substrate. In this study, the metal‐ceramic interface was evaluated using mechanical, chemical, and structural characterization methods. Evaluations of an HA‐coated Ti‐6A1‐4V implant system using a modified short bar technique for interfacial fracture toughness determination revealed relatively low fracture toughness values. Additionally, conventional tensile bond strength testing indicated much lower values than previously reported. Using high resolution electron spectroscopic imaging, evidence of chemical bonding was revealed at the plasmasprayed HA/Ti‐6AI‐4V interface, though bonding was primarily due to mechanical interlock at the interface. This study illustrates the benefits of, and the need for, a multilevel approach to evaluate and improve these plasma‐sprayed ceramicme tai subst rate interfaces.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
