Iron-based biodegradable metals and the method of fabricating are disclosed. The iron-based biodegradable metals, which have an accelerated degradation rate and a yield strength similar to stainless steel, comprises a composite structure of multiple iron layers separated by thin alloying metallic layers. The composite structure are built layer by layer using additive manufacturing technologies. The iron-based biodegradable metals can be fabricated into a small diameter tube for laser cutting into implantable bare metal stents or drug eluting stents with biodegradable polymer coating. The iron-based biodegradable metals can be fabricated and/or machined into orthopedic implants.

The invention relates to a powder mixture for producing an alloy, a powder metallurgy process for producing a material, a material, and a medical implant made from it.

An orthopaedic implant can replace a joint in a patient. The orthopaedic implant includes a first component having a first component surface and a second component having a second component surface. The first component surface and the second component surface mate at an interface. The first component surface includes a metal substrate, a nanotextured surface, a ceramic coating, and a transition zone. The nanotextured surface is disposed directly upon the metal substrate and has surface features in a size of 10.sup.9 meters. The ceramic coating conforms to the nanotextured surface and includes a plurality of bio-active sites configured to attract and retain calcium and phosphorous cations. The transition zone is disposed between the metal substrate and the ceramic coating. The transition zone includes a concentration gradient transitioning from the metal substrate to the ceramic coating and there is no distinct interface between the metal substrate and the ceramic coating.

Absorbable iron-based alloy implanted medical device and manufacturing method thereof. The iron-based alloy implanted medical device comprises an iron-based alloy substrate (11), a degradable polymer layer (13) disposed on a surface of the iron-based alloy substrate (11), and a tannic acid chemical conversion film (12) disposed on a surface of the iron-based alloy substrate (11). After the medical device is implanted into a body, the tannic acid chemical conversion film (12) is configured to protect the iron-based alloy substrate (11) coated thereby from being in contact with a body fluid, thereby ensuring that the device meets a clinical mechanical property requirement in the early stage of implantation. Furthermore, the iron-based alloy implanted medical device has a decreased size, and produces a decreased amount of a corrosive product after being implanted, facilitating faster absorption or elimination of the corrosive product.

An iron based and absorbable implanted prefabricated tube (1) for medical device and preparation method therefor, and a medical device prepared by the prefabricated tube and preparation method therefor. The average nitrogen content of nitrogen in the prefabricated tube is from 0.04-0.4 wt. % or 0.02-0.04 wt. %. The prefabricated tube can be cut along the length direction directly by laser or by machining to obtain multiple absorbable implanted medical devices.

A biocompatible metal implant is provided with a treated surface subject to abrasive mechanical treatment, acid treatment, and sodium treatment, where the biocampatible metal implant treated surface has a macroporosity in the form of cells having dimensions of the order of 50 m to 250 m, the cells having pores of from 1 m to 50 m, and pores with a size of less than a micrometer, homogeneously over the whole of the treated surface, the treated surface having a surface roughness Ra of greater than or equal to 1.90 m.

An exemplary embodiment provides a method of manufacturing a curved porous component having a base material layer and a porous region through one-step laminated-molding, whereby it is possible to reduce a manufacturing time when manufacturing a product and to provide a porous component in which the shape and size of a porous region can be controlled. An implant including the porous component has an increased bone contact ratio, so bone growth between bones can be improved and products fitting to the frames of patients can be easily designed.
