Contact nanofatigue shows crack growth in amorphous calcium phosphate on Ti, Co-Cr and Stainless steel.
TLDR
In this paper, contact nanofatigue was performed on a sintered hydroxyapatite and then on amorphous calcium phosphate splats produced on titanium, stainless steel and Co-Cr surfaces, made either at room temperature or on 250°C preheated surfaces.About:

Biological properties of calcium phosphate biomaterials for bone repair: a review
TL;DR: In this article, the latest studies on the biological properties of CaP biomaterials, including hydroxyapatite (HA), tricalcium phosphate (TCP), and biphasic calcium phosphate (BCP), have been summarized.
Evaluation of Commercial Implants with Nanoindentation Defines Future Development Needs for Hydroxyapatite Coatings
TL;DR: Instrumented nanoindentation was applied to determine the mechanical properties of plasma sprayed hydroxyapatite-coated implants from different commercial vendors to provide a graphical representation of the mechanical property distribution within the coating and provide a basis for coating property refinements.
Journal ArticleDOI
Micro-Raman spectroscopy shows how the coating process affects the characteristics of hydroxylapatite
TL;DR: In this article, the authors compared Fourier transform infrared and Raman spectroscopy to measure the hydroxyl content in rapidly solidified apatites and showed that Raman Spectroscopy is more suitable.
Nanoindentation on the Surface of Thermally Sprayed Coatings
TL;DR: In this article, nanoindentation is used to determine the hardness and elastic modulus on the surface of well spread solidified droplets at the hydroxyapatite coating surface.

TL;DR: It was seen that the vibrational behavior and mechanical performance of the sample containing 15 wt% additives have shown better mechanical characteristic compared to the pure specimen, and it can be concluded that the highest vibration variation is seen in the sample with lower MNPs percentages.

Effects of the substrate on the determination of thin film mechanical properties by nanoindentation
Ranjana Saha,William D. Nix +1 more
TL;DR: In this paper, the effects of the substrate on the determination of mechanical properties of thin films by nanoindentation were examined, and the properties of aluminum and tungsten films on the following substrates: aluminum, glass, silicon and sapphire.

Hip joint loading during walking and running, measured in two patients
TL;DR: In one hip in the first patient and in the second patient the direction of large forces approximated the average anteversion of the natural femur, so the joint loading was observed over the first 30 and 18 months, respectively, following implantation.
Journal ArticleDOI
Measurement of mechanical properties by ultra-low load indentation
TL;DR: In this paper, the use of sharp indenters and how they can be used to measure elastic modulus, hardness, and fracture toughness is discussed, which characterize the three primary modes of deformation in solids.
Journal ArticleDOI
Fracture Surface Energy of Glass
TL;DR: In this article, the double-cantilever cleavage technique was used to measure the fracture surface energy of six glasses and the results ranged from 3.5 to 5.3 J/m2 depending on the chemical composition of the glass and the temperature of the test.

Direct electron microscopy studies of the bone-hydroxylapatite interface.
Brett M. Tracy,Robert H. Doremus +1 more
TL;DR: Conventional and high-resolution imaging in the TEM demonstrated direct chemical bonding between bone and hydroxylapatite, and the bone at the ceramic surface was the same as normal bone away from the interface.
