The thin film formed on the surface of titanium implants through surface modification confers superior wear resistance, corrosion resistance, and biocompatibility. Such surface-modified titanium implants have gained widespread acceptance and application within the clinical medical community both domestically and internationally. However, due to inadequate surface treatment technology, no domestically produced orthopedic titanium implants with reinforced coatings have yet been introduced to the market, leaving users with no choice but to rely on expensive imported alternatives. The successful application of PTO technology to orthopedic titanium implants will fill a gap in the domestic market. We have applied the PTO process to surface-treat titanium bone plates and screws, resulting in a surface hardness approximately three times higher than before. After undergoing 10 cycles of high-temperature, high-pressure sterilization, the treated samples showed no change in color or luster.
Surface treatments for titanium: 1. Treatments to enhance corrosion resistance: atmospheric oxidation and anodizing; these not only improve corrosion resistance but also prevent hydrogen embrittlement; other treatments include platinum plating and palladium oxide/titanium oxide treatments; 2. Treatments to improve wear resistance: nitriding at high temperatures (800–900°C) to achieve a surface Vickers hardness of over 700; Through surfacing, introducing an appropriate amount of nitrogen or oxygen into the argon atmosphere can increase surface hardness by 2–3 times; through ion plating, a layer of titanium nitride approximately 5 micrometers thick is formed on the surface, resulting in a Vickers hardness as high as 16,000–20,000; Chromium plating, etc.; With this basic understanding of titanium and its alloys, one can appreciate their roles in printed circuit board (PCB) production and gain insights into their application and maintenance. Titanium has become the third most promising metal for future applications, following magnesium and aluminum!
The initial research and development focus will be on "the development and application of surface modification technologies for medical titanium materials." Among biomedical metallic materials, titanium and its alloys, due to their excellent comprehensive properties, are the materials of choice for medical implant products such as artificial joints, bone trauma products, spinal orthopedic internal fixation systems, dental implants, dentures, artificial heart valves, and interventional cardiovascular stents. Currently, there is no metallic material superior to titanium for clinical use. Over the past decade, the market growth rate for biomedical materials and products has remained at around 20–25%. It is projected that within the next 10–15 years, the medical device industry-including biomedical materials-will reach the market scale of pharmaceutical products and become a pillar industry of the global economy in the 21st century.
In recent years, titanium rods and titanium alloy materials have found increasingly widespread applications in the biomedical, consumer goods, and industrial sectors. This project employs a new titanium alloy surface modification technology (PTO process) that features proprietary intellectual property and meets international advanced standards. Through advanced processes and low costs, this technology significantly improves the wear and corrosion resistance, biocompatibility, and surface modifiability of titanium materials, thereby expanding their range of applications. The PTO technology is a highly efficient, energy-saving, resource-conserving, and environmentally friendly high-tech solution.
