A short review: hydroxyapatite coatings for metallic implants
The number of orthopedic surgeries will continue increasing over the next decades. The most common causes of orthopedic implant failure after implantation are infections, inflammatory response, corrosion, mismatch in elastic modulus, stress shielding and

Atomic Diffusion in the Surface State of Mott Insulator NiS2 [PDF]
We present resistivity measurements of Mott insulator NiS2 single crystals after heat treatment. We find a strong increase of the low temperature resistivity that relaxes back towards the pristine behaviour over several days with a time constant of 45 h ...

Cr2C3–NiCr VPS thermal spray coatings as candidate for chromium replacement [PDF]
The present investigation has been carried out with the aim of determining the tribological behavior of a VPS chromium carbide coating both in the as-deposited and heat-treated conditions. A commercial powder of Cr2C3–25% NiCr was sprayed employing a VPS

Microstructure and wear resistance of HVOF sprayed WC-10Co-4Cr coating on Ti-6Al-4V
WC-10Co-4Cr coating was deposited on Ti-6Al-4V by the high velocity oxygen fuel spray process to improve the surface hardness and wear resistance. The results show that the porosity of the coating is 2.0%, the microhardness is 1300 HV0.2, the surface ...
