This work investigates the deposition of a hydroxyapatite (HA, Ca10(PO4)6(OH)2) coating onto titanium foam using a blast process and the effect of the process on the macro- and microstructure of the titanium foam. Light microscopy, scanning electron microscopy and energy-dispersive x-ray spectroscopy were used to examine the coating deposition and the macro- and microstructure of the titanium foam. After blasting the macrostructure did not exhibit signs of excessive abrasion or collapsing of the structure that may affect functionality of the foam. Similarly, microstructure was unaffected by the coating process as there is gross plastic deformation and no thermally induced change such as α-case. © 2015 Elsevier B.V. All rights reserved.

Disclosed herein are methods of treating an article surface. The method comprises removing a metal oxide surface from the metal substrate to expose a metal surface; and delivering particles comprising a dopant from at least one fluid jet to the metal surface to impregnate the surface of the article with the dopant. The method also comprises delivering substantially simultaneously a first set of particles comprising a dopant and a second set of particles comprising an abrasive from at least one fluid jet to a surface of an article to impregnate the surface of the article with the dopant.


Disclosed herein are methods of treating an article surface. The method comprises delivering a polymer and drug to a medical implant having a porous surface and using at least one particle stream from at least one fluid jet to subsequently remove the polymer from the outer surface of the metal substrate, thereby retaining the therapeutic agent and polymer within the pores of the implant.
