Abstract

Processing of hydroxylapatite sol-gel films on titanium alloy bone prostheses. A method utilizing non-line-of-sight ion beam implantation and/or rapid thermal processing to provide improved bonding of layers of hydroxylapatite to titanium alloy substrates while encouraging bone ingrowth into the hydroxylapatite layers located away from the substrate, is described for the fabrication of prostheses. The first layer of hydroxylapatite is mixed into the substrate by the ions or rapidly thermally annealed, while subsequent layers are heat treated or densified using ion implantation to form layers of decreasing density and larger crystallization, with the outermost layers being suitable for bone ingrowth.

Method for using titanium-tungsten alloy as a barrier metal in silicon semiconductor processing

Patent Jopke, W. H. Jr. ; Shier, J. S.

A method for producing an NPN semiconductor device which has a titanium-tungsten barrier metal only in the N type contact windows is disclosed. A semiconductor wafer first undergoes the washed emitter process with the result that the N type collector and emitter contact windows are exposed to bare silicon and the P type contact windows are covered by a layer of silicon dioxide. A layer of titanium-tungsten alloy is deposited on the surface of the wafer. The titanium-tungsten layer is etched out of the P type contact regions using standard photolithographic techniques. The underlying layer of silicon dioxide in themore »« less
Alpha-beta titanium-base alloy and method for processing thereof

Patent Adams, R.E. ; Parris, W.M. ; Bania, P.J.

An alpha-beta titanium-base alloy having a good combination of strength, creep resistance and ductility with a relative low-cost alloy composition, said alloy is described consisting essentially of, in weight percent, 5.5 to 6.5 aluminum, 1.5 to 2.2% iron, 0.07 to 0.13 silicon, and balance titanium and incidental impurities in amounts not materially affecting the properties of the alloy.
Auger electron spectroscopic analysis of hydroxylapatite coatings on titanium

Journal Article Van Raemdonck, W. ; De Meester, P. ; Ducheyne, P. - J. Am. Ceram. Soc.; (United States)

Investigating the bioreactive behavior of hydroxylapatite coatings on titanium requires an exact knowledge of structure and composition of the coating. Auger electron spectroscopic analyses were performed in addition to other microstructural analyses. Studies of the outer surface and of the interface between hydroxylapatite and titanium showed that the energy and the signal sensitivity of the Auger phosphorus peak depend on the chemical environment.

Radionuclide bone imaging of femoral prostheses with porous coatings. [Dogs]

Journal Article Spector, M. ; Wigger, W.B. ; Buse, M.G. - Clin. Orthop.; (United States)

Radionuclide bone imaging can be of value in assessing the osseous changes around porous-coated femoral prostheses. Scintimetry appears to be a promising method for determining if radiodensities seen in radiographs of long-term prostheses are indicative of accelerated bone turnover or represent stable osseous structures. In dogs, the periosteal reaction which often occurs within two months of joint surgery masks endosteal-intramedullary osseous changes, including bone ingrowth into the porous coating.
