The landing gear device is an important bearing and maneuverable component of the aircraft, which absorbs and dissipates the impact energy formed by the aircraft and the ground during landing and taxiing. With the continuous development of aviation technology and the continuous improvement of customer needs, landing gear products are constantly upgraded. In order to […]
In chemical plants, the environmental conditions where hydrogen embrittlement occurs can be roughly divided into: non-oxidizing acids with a pH value below 3; strong alkaline solutions with a pH value above 12; organic acids with a pH value of 3; containing F- and I- Salt solution, a neutral solution containing H2S. Under the above conditions, […]
1. Heat treatment furnace Titanium-made equipment heat treatment equipment, mostly choose intermittent type, the best way is electric heating type. For some titanium equipment, vacuum heat treatment is required for heat treatment. There is also a power-saving heating device, that is, a contact-type electric heating furnace. 2. local heat treatment equipment Local heat treatment equipment […]
To explore the feasibility of bio-functional modification by loading RGD peptide on the surface of pure titanium. Studies have pointed out that RGD peptide functionally modified titanium sheets have good biocompatibility, and this titanium surface functionalization modification method is expected to be used to improve titanium implants and improve bone bonding. The active layer of […]
In actual production, an engine valve subjected to oxidation treatment was produced based on this data, and the relationship between the thickness of the oxidized hardened layer and the treatment conditions obtained in the above-mentioned order. And evaluated the fatigue performance and wear resistance. The produced valve was subjected to an S-N curve of an […]
About 120 grades are added with titanium and more than 150 kinds of deformed steel. But the amount of addition is not much, between 0.02% -0.4%. Among about 40 types of cast iron and steel, 13 grades are added with titanium. Generally, the main purpose of adding titanium in 0.08% -0.35% is to refine the […]
In the production process of the furnace coil rolling line, the laminar cooling technology and the method of improving the water supply operation are usually adopted to control and improve the comprehensive mechanical properties and plate shape of the final product. The application of laminar rapid cooling technology is becoming more and more common, and […]

The internal defects of titanium alloy pipe welds are not fully penetrated, which refers to a shortcoming that the workpiece and the weld metal or the weld layer are not partially fused. Incomplete penetration weakens the working section of the weld, constitutes a severe stress concentration, and greatly reduces the strength of the joint. It […]
