Advantages of titanium and titanium alloys and recognition of frames

Advantages of titanium and titanium alloys and recognition of frames

  titanium company metal has good corrosion resistance, and platinum (commonly known as platinum) are similar, very excellent mechanical properties, texture, light, the unit weighs only 48% of the general metal, so titanium frames is the ideal material, because it has no phase than light, flexible, resistant to corrosion. However, the higher cost of production of titanium and titanium glasses, cutting, stamping, welding and plating,, aspects of the process have special high demand (for example: welding must be done in a vacuum), the price is more expensive.
   With the development of titanium materials and processing technology matures, the market has appeared in a variety of titanium-based titanium frame, B titanium, memory titanium. Among them, titanium frames purity materials required to achieve 99.9% (excluding gaskets, screws, stipules and leg sets), which identifies all known PURETITANIUM, or abbreviated as Ti-P and so on. However, driven by the interests of individual vendors for some non-pure titanium or titanium alloy materials have also been identified above, the majority of consumers lack titanium frames plus the ability to identify, causing consumers to wear titanium frame after frame of Health rust, skin allergies and other phenomena, harm the interests of consumers. Following the first volume of a few simple methods to identify titanium frames.

         1， A hand weigh the weight, the proportion of alloy frame usually about 8.9g / cm3, the proportion of titanium frame is about 4.5g / cm3, due to the weight of the titanium alloy materials equivalent to half the frame, hand weigh up more light. This is one of the easiest way to distinguish non-titanium frame titanium frame.

         2, observation stems nose pads and nose stipules bucket weld, welding titanium material is vacuum anaerobic Welding, welding marks here as "step" shape, welding alloys for welding, welding marks for "slope "shape, which is one of the effective methods of non-titanium frame titanium frame and distinction.

         3, observe whether there is hinged at the gasket, titanium frames in the hinge should not make direct contact with titanium and titanium, or prone junction wrinkled, temples and close them poor phenomenon. Usually two thin shim mosaic hinge titanium frames, the upper and lower hinge separated. Therefore, check whether the hinge pads, titanium frames also identify whether a good method.

         4, with the magnet magnetic hair should do, will try to loosen the hinge frame, under the free active magnet to attract, as the temple attracted by the magnet shaking, indicating that this is not a pure titanium frame, otherwise it shows that the frames may be pure titanium frame.

medical titanium

   The past 10 years, the growth rate of biomedical materials and products market has remained at around 30%. In the biomedical materials, titanium and titanium alloys due to its pro-biotic characteristics, has become artificial joints, dental implants, interventional cardiovascular stents and other implantable medical class product material of choice. According to incomplete statistics, the world's disabled population of the world accounted for 1/20, and joint replacement patients receiving only about 1.5 million cases per year, and the number of those who are far from the actual needs replacement. Therefore, as a biomedical material of choice for Medical titanium alloy huge market demand. In our case, biomedical materials for surgical implant into the body about 80% of imported products, the high price limits its wide application. Therefore, increased research and development efforts titanium medical imperative. Has developed a variety of alloy materials are varying degrees of defects, such as relatively low wear resistance, corrosion resistance and can be further improved, the biological activity is not ideal. In order to improve the performance of medical titanium, but also in two ways, one is optimized alloy composition, the second is the titanium alloy surface modification.
    Medical analysis is mainly based on Medical grade titanium alloycomponents for medical research and development base five system Ti-Nb, Ti-Mo-based, Ti-Zr-based and Ti-Ta-based, Ti-Al-based alloy, and the selected literature are the art cited higher frequency patented technology literature. TiMo and TiNb tin alloy is the focus of the study, from 1982 to date, has submitted more patent applications; Judging from the number of alloying elements, TiNb alloy from the initial binary alloy gradually developed into triples, until now four element alloy; alloying element selected from the terms of the types, TiNb alloy from the initial metallic elements Zr, Fe, Ta, Sn, to the semiconductor elements Si, Ge, Ga, alloy elements are added to render the non-metallic species from the metal species trend. In future research, we can study them in a targeted manner to strengthen the weak technical means, look for opportunities to get involved in fewer areas in others. China needs to be optimized to strengthen ties in research and production, and increase the number of applications, strengthen innovation, and improve the layout and other aspects of the patent. The number of applications of titanium in the medical field has entered a steady growth, but the main universities and research institutions of the applicants, compared with foreign-based companies to the applicant, to the industrial transformation of scientific research is more a long road. Therefore, the need to strengthen domestic enterprises cooperation with universities and research institutions. Meanwhile, with the market needs to find technical focus and technical weaknesses, to promote the transformation of scientific and technological productivity. At present, many domestic applicants only concerned with the domestic market, even developed the core technology, but also only consider seeking protection in the country while ignoring the submission of applications for patents in foreign countries. If the technology or product enters the foreign market, because there is no protected by patent, the market competitiveness of their products will be greatly weakened, and even cause as a result of the infringement and can not enter foreign market. Therefore, the applicant should increase domestic foreign patent applications, improve the number of PCT patent application or with the family, to further improve the worldwide patent portfolio。
