At present, the only countries in the world that truly master the production of fasteners for commercial aircraft are the United States, Germany, and Japan, and no one in China can produce titanium alloy parts that meet commercial aircraft standards. my country has invested 200 million yuan to establish a project production base in Yantai, which is mainly engaged in the research and development and production of commercial aircraft titanium alloy components, and provides high-end parts for the large commercial aircraft of COMAC. It is expected that the annual income can reach 1 billion yuan after reaching production. To be put into production, a research process is still needed.
My country plans to fly for the first time in 2015, a commercial "large aircraft" developed and produced by itself. Each aircraft requires 1.1 million standard parts, of which more than 200,000 pieces of titanium plates and titanium alloy parts. Commercial aircraft titanium standard parts and titanium special-shaped parts mainly include: titanium bolts, studs, screws, nuts, washers, pins, rivets, etc. Titanium plates and titanium special-shaped parts can greatly reduce the structural weight of the aircraft, improve flight performance, and reduce fuel consumption .
Titanium nitride has high hardness, wear resistance, corrosion resistance and good decorative properties. More than 50% of titanium rods are used in the aviation field in the production and processing of titanium worldwide. The lightweight of aircraft is the constant theme of the development of the aviation industry. In the next 20 years, the demand for new passenger aircraft will be about 10,000. Lightweight will greatly increase the amount of titanium and titanium alloys. In other fields, the increase in demand for titanium is mainly concentrated in the fields of seawater desalination equipment, LNG equipment, nuclear power plants, chlor-alkali equipment, PTA equipment, roofs of large buildings, ships, and medical surgery.
Titanium rods and their titanium alloys have outstanding advantages such as high specific strength, corrosion resistance, non-magnetic, low damping, good high and low temperature performance, good compatibility with carbon composite materials, and good biocompatibility, but their wear resistance And the hardness is very poor. In order to solve the shortcomings in this respect, the vacuum titanium nitride film process saves this problem very well. For this reason, the titanium nitride stripping method will be introduced, and the defective film in mass production should be removed in time.
