Product introduction
Turbine blades are a key component of the turbine part of a gas turbine engine. They are responsible for converting the energy of high-temperature and high-pressure gas into mechanical energy to drive the engine.
Product features
High Temperature Resistance
The operating temperature of turbine blades typically reaches 980°C to 1100°C. To meet this challenge, we use nickel-based single-crystal high-temperature alloy materials, whose creep resistance can reach 20 MPa at 1,000°C, which is significantly better than the 15 MPa of traditional polycrystalline alloys and can maintain better performance under the same high-temperature conditions. Low deformation rate.
Fatigue Resistance
Fatigue resistance refers to the ability of a material to resist crack propagation and maintain structural integrity under repeated stress conditions. The fatigue life of our blade products can reach 10^7 cycles, which is more than 30% higher than that of ordinary blades. They can withstand centrifugal stress of up to 200 MPa during high-speed rotation without cracking.
Efficient Cooling
Our turbine blades use advanced internal micro-channel cooling technology, which uses high-pressure cooling gas to absorb heat while flowing through the channels, thereby reducing the blade surface temperature by about 200°C. The lower temperature significantly reduces the damage to the blades caused by thermal stress, extending their service life by 30%.
Corrosion Resistance
Turbine blades are exposed to sulfides, oxides and other corrosive compounds in high-temperature gas environments. We use advanced thermal barrier coating technology to accurately control the coating thickness between 0.2-0.5 mm, which effectively blocks corrosive substances in the gas, improves the blade's oxidation resistance by 50%, and increases its resistance to sulfide corrosion by 35%.
