3D-printed titanium hip implant features fully porous acetabular cup
March 3, 2016
Source:
Smith & Nephew, Andover, Mass., introduces its first 3D-printed titanium hip implant, the new Redapt revision acetabular fully porous cup with Conceloc technology. To support bone growth, the 3D manufacturing process will be used to produce an entirely porous implant, one that mimics the structure of cancellous bone.
The company noted that the Conceloc advanced porous titanium technology is an alternative to external porous coatings, such as sintered beads or fiber mesh, used in other uncemented implants. The new Redapt cup has been developed for use in revision cases where compromised bone makes implant fixation and stability more difficult.
"Bringing to market a 3D-printed titanium acetabular cup for difficult revision procedures is just one example of the potential of this remarkable technology," says Smith & Nephew global reconstruction vice-president Mike Donoghue.
Redapt variable-angle locking screws, as well as traditional non-locking screws, work within the implant's geometry to provide both compression and a rigid construct to the acetabular shell. The 3D-printed titanium hip implants are available at selected sites in the United States.

U.S. stainless steel sheet and strip producers file antidumping petitions against China
February 17, 2016
Source:
AK Steel Corp., ATI Flat Rolled Products, North American Stainless, and Outokumpu Stainless USA, the four principal U.S. producers of stainless steel sheet and strip, have filed antidumping and countervailing duty petitions charging that unfairly traded imports of stainless steel sheet and strip from the People's Republic of China are causing material injury to the domestic industry.
The antidumping margins alleged by the domestic industry range from 53.69 to 83.24% ad valorem (according to value). The domestic industry's countervailing duty petition alleges that the Chinese government has provided significant subsidies to Chinese producers. The petitions were filed concurrently with the United States Department of Commerce and the United States International Trade Commission.
The domestic industry filed its petitions for relief in response to large and increasing volumes of low-priced imports of stainless steel sheet and strip from China over the past three years that have injured U.S. producers. The volume of imports of stainless steel sheet and strip from China has increased by 133% since 2013. Chinese products accounted for 81.2% of the total increase in U.S. stainless steel sheet and strip imports during the past three years.
The petition alleges that Chinese producers have injured the domestic industry by selling their stainless steel sheet and strip at unfairly low prices that significantly undercut domestic market prices. As a result of this unfair competition, the domestic industry has suffered declines in sales, production, employment, prices, and profits.
Commerce Department and U.S. International Trade Commission will now begin their preliminary investigations, which are expected to be finalized during the first quarter. The entire investigative process will take approximately one year, and it is expected to be complete in the first quarter of 2017.

High-strength magnesium-lithium alloy weighs half as much as aluminum
January 1, 2016
Source:
The University of New South Wales and Monash University, Australia, announce that a team of researchers has developed a high-strength magnesium-lithium alloy with density of 1.4 g/cm3, 50% less than aluminum and 30% less than magnesium. The researchers have shown that the alloy forms a protective layer of carbonate-rich film upon exposure to air, making it immune to corrosion. The finding is published online in the 19 October edition of Nature Materials.
Prof. Michael Ferry, of UNSW's School of Materials Science and Engineering, says that the excellent corrosion resistance of the alloy was observed by chance, when the team noticed that a heat-treated sample in a beaker of salt water showed no corrosion after several hours. Normally magnesium would have been extensively corroded.
The researchers then designed a magnesium-lithium alloy of specific composition together with a processing sequence consisting of hot extrusion, heating and water quenching, low-temperature aging, and cold rolling.
"This is the first magnesium-lithium alloy to stop corrosion from irreversibly eating into the alloy, as the balance of elements interacts with ambient air to form a surface layer which, even if scraped off repeatedly, rapidly reforms to create reliable and durable protection," says Prof. Ferry.
The UNSW team partnered with scientists on the Powder Diffraction beamline at the Australian Synchrotron, to confirm that the alloy contains a unique nanostructure that enables the formation of a protective surface film.
Prof. Nick Birbilis (shown in the photo), School of Materials Science and Engineering at Monash University, says viewing unprecedented structural detail of the alloy through the Australian Synchrotron will enable the team to work toward commercializing the new metal.
‘We're aiming to take the knowledge gleaned at the Australian Synchrotron to incorporate new techniques into the mass-production of this unique alloy in sheets of varying thickness, in a standard processing plant," Prof. Birbilis said.

Silver nanoparticles in polymer coating prevent infections in dental implants
November 8, 2015
Source:
Researchers at the Fraunhofer Institute, Germany, have reportedly developed DentaPlas, an antimicrobial coating for dental implants that consists of three layers, with two plasma polymer layers surrounding a center layer of silver nanoparticles. Within this structure, a biocide reservoir is formed, and the outermost layer releases the ions.
Scientists can tailor the silver concentration as well as the thickness of the layers and their porosity. This allows the silver ions to penetrate the outermost plasma polymer layer over a set period of time. When the silver reservoir is exhausted, no more silver ions are released, thus avoiding any long-term toxic effects.
In trials of finished implants and titanium test samples, the team demonstrated that the DentaPlas coating is not only anti-microbial, but also fully biocompatible and sterilizable. They confirmed the mechanical stability and robustness of the DentaPlas coating in trials using the lower jawbones of pigs taken from butcher shops. Here, they subjected the DentaPlas-coated implants to the rigors of being screwed into place with instruments in modern dental practice.
The DentaPlas coating passed this stress test with no problems. Project partner and Fraunhofer spinoff Bio Gate AG successfully transferred the processes of coating the test samples and titanium screws to its own production facilities. This medical technology company is also the manufacturer of the DentaPlas three-layer coating system.
A demonstration unit of the plasma polymer coating is currently available. Researchers will be presenting a dental implant featuring the DentaPlas coating at the MEDICA trade fair in Düsseldorf from November 16 -19 at the joint Fraunhofer booth (Hall 10, Booth G05).

Bodycote expands capacity for treating specialty stainless steels in Ohio
October 6, 2015
Source:
Bodycote, England, announces that it has expanded capacity for specialty stainless steel processes (S3P) at its facility in London, Ohio, and is building a new S3P facility in North Carolina that is to open in 2016. These technologies are dedicated to improving resistance to surface wear such as cavitation erosion, abrasion, and especially galling in stainless steels, nickel-base alloys, and cobalt-chromium alloys, while maintaining corrosion resistance.
Many surface treatments, when applied to stainless steel, negatively affect the metal's inherent corrosion resistance. However, the S3P process imparts increased mechanical and wear properties without adversely affecting corrosion resistance.
Specialty stainless steel processes (S3P) featuring Kolsterising and Nivox technology, offer unique surface hardening solutions for austenitic stainless steel, nickel-base alloys, and cobalt-chromium alloys. Benefits include higher surface hardness to 900-1300 HV0.05, depending on base material and surface conditions. Treated alloys are highly resistant to surface wear environments such as sliding combined with abrasive wear and cavitation erosion. The paramagnetic properties of austenitic materials remain unchanged after treatment.
