Baoji Dingding Titanium | Efficient Transmission Core of Titanium Alloy Impeller and Shaft Forging Power System

Titanium alloy impeller and shaft forgings serve as the "power heart" of aviation engines, marine propulsion systems, chemical compressors, and other equipment. Their mechanical properties and transmission efficiency directly determine the overall operational efficiency of the machine. Baoji Dingding Titanium Products Co., Ltd. is based on the advantages of the "China Titanium Valley" forging industry, focusing on the research and production of mainstream titanium alloy impeller and shaft forgings such as TC4, TC11, TA2, etc. Through the integrated process of "precision forging+CNC finishing", the forging size tolerance is ≤± 1mm, the surface roughness Ra is ≤ 1.6 μ m, and it is perfectly adapted to extreme dynamic conditions such as high speed, high temperature, and strong corrosion.

1、 Core advantage: Performance barrier of titanium alloy impeller and shaft forgings

Compared to traditional materials such as stainless steel and high-temperature alloys, titanium alloy impellers and shaft forgings exhibit irreplaceable comprehensive advantages in power transmission scenarios

High strength fatigue resistance performance

The tensile strength of TC11 titanium alloy forgings is ≥ 1000MPa. After multiple rounds of forging, the grain size is refined to 2-4 μ m, and the fatigue cycle resistance is more than 10 times. It can resist high-frequency stress impact during high-speed operation, avoid impeller cracking and shaft deformation.

High temperature stability characteristics

At a high temperature of 500 ℃, TC4 and TC11 titanium alloys can still maintain a strength of over 85% at room temperature without obvious creep phenomenon. They are suitable for high-temperature power systems such as aviation engines and gas turbines, and have a temperature resistance limit 200 ℃ higher than aluminum alloy forgings.

Lightweight and High Efficiency

The density is only 4.51g/cm ³, which is 40% -50% lighter than steel forgings of the same specification. It can significantly reduce the starting energy consumption and operating inertia of the power system, improve the aerodynamic efficiency of the impeller by 10% -15%, and help the equipment achieve energy conservation and efficiency improvement.

Global corrosion resistance

The surface dense oxide film can resist corrosion from seawater, chemical media, aviation fuel, etc. The corrosion rate after 5000 hours of salt spray testing is ≤ 0.0003mm/year, and the service life is extended by more than 8 times in corrosive scenarios such as marine and chemical industries.

3、 Core application area: Scenario based implementation of power systems

1. Aerospace field: the "transmission core" of high-end power

Titanium alloy impellers and shaft forgings are key components of aerospace power systems, bearing the high-efficiency transmission requirements under extreme working conditions

-TC11 titanium alloy compressor impeller is used in aviation engines. Under high temperature of 500 ℃ and high-speed operation at 20000rpm, the blades are not deformed or broken, and the aerodynamic efficiency is 12% higher than that of high-temperature alloy impeller, which helps to improve the thrust to weight ratio of the engine;

-The TC4 transmission shaft is adapted to spacecraft attitude control engines, with lightweight characteristics that reduce satellite launch loads and non-magnetic properties that avoid interference with navigation systems. It has passed aerospace grade environmental simulation tests.

2. Ship and Ocean Engineering Field: Corrosion resistant and Efficient 'Propulsion Tool'

Faced with ocean corrosion and the demand for high-speed propulsion, titanium alloy forgings have shown significant advantages:

-TA2 pure titanium impellers are used in seawater pumps and propulsion systems for ocean going vessels. After 5000 hours of seawater immersion, there is no rust, and the smoothness of the blade surface ensures propulsion efficiency. The service life of TA2 pure titanium impellers is extended by 10 times compared to copper alloy impellers;

-TC4 thick walled shaft forgings are used as the power transmission shaft for deep-sea exploration robots, which can withstand a deep-sea pressure of 3000 meters and resist seawater corrosion, ensuring stable power transmission for underwater operations of the robot.

3. Chemical and energy fields: "Power guarantee" for strong corrosion conditions

In chemical corrosion and energy high-pressure scenarios, titanium alloy forgings solve the problem of traditional materials being prone to failure:

-TC4 titanium alloy impeller is used in chemical centrifugal compressors, which can resist strong corrosive media such as hydrochloric acid and acetic acid. The precision molding of the blades ensures gas compression efficiency and has been applied in the raw material conveying system of large chemical enterprises;

-TA2 pure titanium shaft forgings are suitable for delivery pumps in nuclear power auxiliary systems, with excellent radiation corrosion resistance and stable operation under complex working conditions, ensuring the safety of nuclear power systems.

4. General industrial and medical fields: precision adapted "multifunctional components"

-General Industry: TC4 impeller and shaft forgings are used for hydraulic systems in new energy wind power equipment, with lightweight characteristics to reduce fan loads and fatigue resistance to ensure long-term outdoor operation;

-Medical equipment: TA2 pure titanium impeller is used for medical centrifuges, with excellent biocompatibility to avoid blood contamination. The precision machining of the blades ensures centrifugal separation accuracy and is suitable for high-end medical testing equipment.

4、 Quality assurance: Military grade forging and full process control

1. Raw material traceability: High purity sponge titanium with a purity of ≥ 99.8% is used, melted in a vacuum consumable arc furnace at least 3 times, and each batch of raw materials is accompanied by a composition analysis report to ensure that the titanium ingot composition is uniform and free of segregation;

2. Precision forging: The impeller adopts the "integral forging+five axis CNC milling" process, with a blade surface accuracy of 0.02mm; the shaft adopts the "constant temperature forging+straightening precision grinding" process, with a straightness error of ≤ 0.01mm/m, eliminating internal stress;
