Performance Analysis Of Titanium Anode And Titanium Metal

1. Good low temperature resistance

Likun Titanium Industry explained the low temperature titanium alloy represented by titanium alloy TA7 (Ti-5Al-2.5Sn), TC4 (Ti-6Al-4V) and Ti-2.5Zr-1.5Mo, whose strength increases with the decrease of temperature. But the plastic change is not big. It maintains good ductility and toughness at low temperatures of -196-253℃, avoids cold brittleness of metals, and is an ideal material for cryogenic containers, storage tanks and other equipment.

2.Strong damping resistance

Metal titanium has the longest vibration decay time compared with steel and copper after being subjected to mechanical vibration and electrical vibration. This performance of titanium can be used as a tuning fork, medical ultrasonic pulverizer vibrating element and high-end acoustic speaker vibrating film.

3. Non-magnetic and non-toxic

Titanium is a non-magnetic metal, and it will not be magnetized in a large magnetic field. It is non-toxic and has good compatibility with human tissues and blood, so it is adopted by the medical profession.

4. Low modulus of elasticity

The elastic modulus of titanium is 106.4GMPa at room temperature, which is 57% of steel.

5. Suction performance

Titanium is a very active metal with chemical properties. It can react with many elements and compounds at high temperatures. Titanium getter mainly refers to the reaction with carbon, hydrogen, nitrogen and oxygen at high temperature.

6.Small density, high specific strength

The density of metallic titanium is 4.51g/cm3, which is higher than aluminum but lower than steel, copper, and nickel, but its specific strength is the first among metals.

7. Corrosion resistance

Titanium is a very active metal, its equilibrium potential is very low, and it has a high tendency of thermodynamic corrosion in the medium. Likun Titanium found that, but in fact, titanium is very stable in many media. For example, titanium is corrosion resistant in oxidizing, neutral and weak reducing media. This is because titanium and oxygen have a great affinity. In the air or in an oxygen-containing medium, a dense, strong adhesion and inert oxide film is formed on the surface of titanium, which protects the titanium matrix from corrosion. Even due to mechanical wear, it will quickly heal itself or regenerate. This indicates that titanium is a metal with a strong tendency to passivation. The titanium oxide film always maintains this characteristic when the medium temperature is below 315℃.

In order to improve the corrosion resistance of titanium, surface treatment technologies such as oxidation, electroplating, plasma spraying, ion nitriding, ion implantation, and laser treatment have been developed to enhance the protection of the titanium oxide film and obtain the desired corrosion resistance. effect. In response to the need for metal materials in the production of sulfuric acid, hydrochloric acid, methylamine solution, high-temperature wet chlorine, and high-temperature chloride, a series of corrosion-resistant titanium alloys such as titanium-molybdenum, titanium-palladium, and titanium-molybdenum-nickel have been developed. Titanium castings use titanium-32 molybdenum alloy, titanium-0.3 molybdenum-0.8 nickel alloy is used in the environment where crevice corrosion or pitting corrosion often occurs, or titanium-0.2 palladium alloy is used locally in titanium equipment, and they are all well used. effect.

8. Good heat resistance

The new titanium alloy can be used for a long time at 600℃ or higher.

9.The tensile strength is close to its yield strength

Likun Titanium explains that this performance of titanium shows its high yield ratio (tensile strength/yield strength), which means that the plastic deformation of metallic titanium materials is poor during forming. Due to the large ratio of the yield limit of titanium to the modulus of elasticity, the resilience of titanium during molding is large.

10. Good heat transfer performance

Although the thermal conductivity of metallic titanium is lower than that of carbon steel and copper, due to the excellent corrosion resistance of titanium, the wall thickness can be greatly reduced, and the heat exchange between the surface and the steam is dropwise condensation, which reduces the heat group and is too surface. Without scaling, the thermal resistance can be reduced, and the heat transfer performance of titanium can be significantly improved.
