Porous titanium obtained by P/M

Le Journal de Physique IV, 2001
Porous materials are needed for the development of new surgical implants where reliable implant-to-bone fixation is accomplished. Here we report a method based an P/M technology to obtain titanium alloys with controlled porosity and good mechanical properties due to the use of nanocrystalline powders, with means of the traditional sintering techniques ...

A lanthanum titanium porous glass ceramic

Journal of Materials Science, 1983
Studies on the substitution of the end-member oxides in the ternary sodium borosilicate system have included work on the replacement of SiO2 with combinations of La2O3 and TiO2 which after heat treatment resulted in leachable sodium borate and insoluble La2O3-TiO2 ceramic phases.

[Titanium porous-surface screw implant].

Zhonghua kou qiang yi xue za zhi = Zhonghua kouqiang yixue zazhi = Chinese journal of stomatology, 1996
Titanium porous-surfaced screw implant was made by plasma-spray with Ti powder. The pore size was 80-300 microns. Two groups of implants were implanted in the mandibles of 15 dogs. Group A: porous-surfaced screw implant: Group B: smooth surface screw implant. The bone healing was evaluated by L. M. SEM. and shear strength testing. The results show that

Combustion synthesis of porous titanium microspheres

Materials Chemistry and Physics, 2013
Abstract The synthesis of titanium porous microspheres by a combustion technique was studied under an argon atmosphere by using a TiO 2  − 2.5Mg reactive mixture. The precursor, a fine TiO 2 powder, was thermally treated in the range 600–1300 °C prior to the combustion experiments.

Porous Titanium Alloy for Prosthesis Attachment

1983
Void metal composite (VMC) is a porous metal developed to fix a prosthesis to bone by tissue ingrowth. The material is made by techniques which produce structures with controlled porosity, density, and physical properties. The ability to produce a range of structures creates opportunities to study the effects of pore size, shape, and density on bone ...

Titanium and Titanium Alloy Prostheses with Porous Fiber Metal Coatings

1984
In an effort to improve the long-term reliability of permanent implants, several new techniques have been investigated for the skeletal fixation of the components. Independent work at various laboratories has shown mechanical interlocking by bone ingrowth into porous coatings to be one of the most promising techniques in this regard [4, 8, 10, 11, 13].

[Nephropexy with superelastic porous titanium nikelide].

Urologiia (Moscow, Russia : 1999), 2007
The authors propose a novel method of operative treatment of nephroptosis based on application of superpermeable porous titanium nikelide. The method provides a complete recovery of blood flow and urodynamics in the low kidney in strict fixation of the kidney in its physiological state due to formed functional scar (invasion of the vessels and collagen
