Introduction To Technology Of Titanium Surface Treatment Modification

Sep. 23, 2019

The surface of the titanium material is surface-modified to form a film on the surface of the titanium implant to make the implant have better wear resistance and biocompatibility. The surface-modified titanium implant has been obtained at home and abroad. Universal acceptance and application in the clinical medicine community. Due to the lack of surface treatment technology, there are no domestic orthopedic titanium implant products with reinforced membranes on the market, and only high-priced imported similar products can be used. The successful application of PTO technology in orthopedic titanium implants will fill the domestic gap. The surface of the titanium plate and the bone nail was treated by the PTO process, and the surface hardness after treatment was increased by about 3 times. After the high temperature and high pressure disinfection test of the sample after treatment, the color and gloss did not change.

Surface treatment of titanium shared by Titanium Alloy Plate Manufacturer:

1. Enhanced corrosion resistance treatment

Atmospheric oxidation treatment and anodizing treatment; not only can improve corrosion resistance, but also prevent hydrogen embrittlement; in addition, platinized, palladium oxide / titanium oxide treatment;

2. Improve wear resistance

Nitriding treatment at high temperature (800-900 °C), the surface Vickers hardness is up to 700 or more; by surfacing, adding appropriate amount of nitrogen or oxygen in argon gas, the surface hardness can be increased by 2-3 times; Through ion plating, a titanium nitride layer is formed on the surface, the thickness is about 5 microns, and the surface Vickers hardness is as high as 16,000-20,000 chrome; etc. Through the above simple understanding of titanium metal and its alloy, we will also understand titanium and The role of its alloy in the production of circuit boards will be instructive in terms of use and maintenance; titanium metal has become the third largest future application prospect after magnesium and aluminum as a wide range of metals!


Among biomedical metal materials, titanium and its alloys are excellent joint performance, such as artificial joints, bone trauma products, spinal orthopedic internal fixation systems, dental implants, dental trays, artificial heart valves, interventional cardiovascular stents, etc. The preferred material for endophytic products, currently, there is no better metal material than titanium for clinical use. In the past 10 years, the market growth rate of biomedical materials and products has been maintained at around 20-25%. It is expected that in the next 10-15 years, the medical device industry including biomedical materials will reach the scale of the pharmaceutical products market and become the 21st century. The pillar industry of the world economy.


Titanium Rod and titanium alloy materials have been used more and more widely in biomedicine, daily necessities, and industrial fields in recent years. This project adopts titanium alloy surface modification new technology (PTO process) with independent intellectual property rights and international advanced level. This technology can significantly improve the wear resistance and biocompatibility of titanium materials with advanced technology and low cost. Surface modification makes titanium materials more widely used. PTO technology is an environment-friendly high-tech that is efficient, energy-saving and resource-saving.
