Recently, the Korea Electric Research Institute (KERI), an electric power research institute affiliated to the National Institute of Science and Technology of the Ministry of Science, Technology and Information, said that the research team of the Electric Medical Device Research Center has developed a surface treatment of titanium materials using femtosecond lasers. Technology. Femto second […]
Titanium is a very active metal element and can interact with all elements. In heating, titanium can interact with oxygen to form an oxide film on the surface. At different heating temperatures, the structure and properties of the oxide film are different. The thermoforming of titanium plates is more complicated, and the mechanical properties of […]
Advantages of titanium coil: Excellent corrosion resistance in many media The surface is smooth and clean, no scale layer Small density and high strength, so light weight Titanium heat exchanger Ten properties of titanium in titanium coil: Small density and high specific strength The density of titanium metal is 4.51g / cm3, which is higher […]
Bone plates can be used throughout the body to fix the fracture site during the healing process, and its shape and size are ever-changing. These components vary widely and are often referred to as internal fixators or trauma plates. Their design and manufacture are highly specialized, such as spinal fixation and fusion applications. These implants […]
The welding performance of titanium equipment and titanium alloys has many significant characteristics. These welding characteristics are determined by the physical and chemical properties of titanium and titanium alloys. 1. The influence of gas and impurity pollution on welding performance At room temperature, titanium and titanium alloys are relatively stable. However, the test results show […]
The composition of titanium alloy TC4 material is Ti-6Al-4V, which belongs to (α + β) type titanium alloy and has good comprehensive mechanical and mechanical properties. Bigger than strength. The strength sb of TC4 = 1.012GPa, density g = 4.4 * 103, specific strength sb / g = 23.5, and the specific strength sb / […]
1. Preparation before welding The surface quality of the weldment and titanium wire has a great influence on the mechanical properties of the welded joint, so it must be cleaned up strictly. Iron plate and titanium welding wire can be cleaned by two methods: mechanical cleaning and chemical cleaning. Mechanical cleaning Welding parts with low […]
National Standards for Titanium and Titanium Alloys Titanium and titanium alloy grades and chemical composition (GBIT362.10.1-2007) Tolerance of chemical composition and composition of titanium and titanium alloy processed products (GB / T36200.2-2007) Titanium and titanium alloy sheet (G BIT362 1-2007) Titanium plate for plate heat exchanger (G BITl 4845 ~ 93) Titanium and titanium alloy […]
After forging, the metal can improve its structure and mechanical properties. After hot working and deformation of the casting structure, the original coarse dendrites and columnar grains become fine-grained and uniform-sized equiaxed recrystallized structures due to the deformation and recrystallization of the metal, so that the original segregation, The compaction and welding of looseness, porosity, […]
The welding performance of titanium coils and heat exchangers has many significant characteristics. These welding characteristics are determined by the physical and chemical properties of titanium and titanium alloys.
