Various examples are provided related to blood-interface materials for metallic biomedical implants and devices. In one example, a bio-compatible implant or device includes an organosilane plasma polymerization (OPP) coating disposed on a surface of a metallic structure. The OPP coating can include inorganic silica disposed on bare metal of the metallic structure and forming a nano-textured surface. In another example, a biocompatible implant or device includes a composite coating disposed on a surface of the metallic structure. The composite coating can include silica-DEA, silica-MEA or silica-TEA coating disposed on bare metal of the metallic structure and forming a nano-textured surface. In another example, a method includes providing a metallic structure and exposing it to an OPP process to form a coating on the surface of the metallic structure to form the bio-compatible implant or device.

The invention relates to an implant and a set for producing an implant and their uses. Furthermore, the invention describes a method of making an implant as per the invention. An implant for producing bone implants with improved mechanical characteristics, especially with adjustable mechanical characteristics, is provided via the invention. The implant as per the invention made up of a fiber composite material contains resorbable mineral bone cement as the matrix material, to which reinforcing, long metal fibers and/or endless metallic fibers with an aspect ratio of at least 100:1 are added in the form of at least one fiber structure that provides a framework and that preforms the contour of the implant.

Guide wire devices fabricated from a linear pseudo-elastic NiTi alloy and methods for their manufacture. The NiTi alloy that includes nickel, titanium, and about 3 atomic % (at %) to about 30 at % niobium (Nb). Cold working the NiTi alloy stabilizes the alloy's martensitic phase and yields a linear pseudo-elastic microstructure where reversion to the austenite phase is retarded or altogether blocked. The martensitic phase of cold worked, linear pseudo-elastic NiTiNb alloy has an elastic modulus that is considerably higher than the comparable cold worked, linear pseudoelastic binary NiTi alloy. This yields a guide wire device that has better torque response and steerability as compared to cold worked, linear pseudoelastic binary NiTi alloy or superelastic binary NiTi alloy.

A method of making a composite, including mixing ZnO nanoparticles (NPs), Mg particles, and Zr particles under an inert atmosphere to form a powder mixture, compacting the powder mixture at a pressure of 500-600 MPa for at least 1 minute to form a compacted mixture, and sintering the compacted mixture at a temperature of 400-500 C. for at least 1 hour to form the composite. The composite includes 1-10 wt. % of the ZnO NPs and 0.1-5 wt. % of the Zr particles, based on a total weight of the composite, the Zr particles and the ZnO NPs are homogeneously dispersed in a matrix of the Mg particles in the composite, the Mg particles have an average grain size of 5-10 m in the composite, and the Zr particles and the ZnO NPs separately form aggregates at grain boundaries of the Mg particles in the composite.

The present disclosure relates to medical implant components comprising a biocompatible-bioactive composite material layer (BACL), methods of making the medical implant components and applications of the medical implant components.

The invention discloses a cosmetic ceramic massage head formula and a preparation technology. The formula comprises the following raw materials: aluminum oxide fine powder, fused quartz powder, kaolin, calcium carbonate and graphene. The preparation technology comprises the steps of making ceramic slurry; injecting the ceramic slurry into a mold to make a blank, modifying and blowing the blank dry, placing the blank in a low-temperature furnace, a degreasing furnace and a high-temperature furnace separately to complete the preparation; vibrating and polishing, and soaking and cleaning to obtain a finished product. The impact strength is high, the tear resistance is good, and through adoption of the preparation technology, serious deformation with changes in temperature during preparation and explosion during high-temperature sintering are not easy to occur, so that the stability and fullness, and surface strength and abrasive resistance are improved, and accordingly the service life is prolonged.
