Product Introduction

Compressor blades are used at different temperatures than turbine blades in turbomachinery such as aircraft engines and gas turbines. The main function of compressor blades is to compress the incoming air, increase its pressure and temperature, and thus provide high-pressure gas for the combustion process.

Temperature of compressor blades
Low-pressure compressor (LPC)
Temperature range: Usually between 150°C and 300°C.
Material selection: Aluminum alloys and titanium alloys are generally used because of their light weight and good mechanical properties.
High-pressure compressor (HPC)
Temperature range: Usually between 300°C and 700°C.
Material selection: Titanium alloys and nickel-based high-temperature alloys are used because of their excellent strength and durability at higher temperatures.

Material selection and temperature range
Aluminum alloy

Application: Mainly used for low-pressure compressor blades.
Advantages: Light weight and low manufacturing cost.
Disadvantages: Poor high-temperature performance, not suitable for high-temperature environments.
Titanium alloy

Application: Used for low-pressure and high-pressure compressor blades.
Advantages: light weight, high strength, corrosion resistance, and good performance at higher temperatures.
Temperature range: can be used in environments up to 600°C.
Nickel-based high-temperature alloys
Application: mainly used for high-pressure compressor blades.
Advantages: high temperature strength, excellent creep resistance and oxidation resistance.
Temperature range: can be used in environments up to 700°C.

Manufacturing process of compressor blades
Forging: Titanium alloy and nickel-based alloy blades are often manufactured by forging process to improve the density and mechanical properties of the material.
Precision casting: used to manufacture nickel-based alloy blades of complex shapes to ensure the performance of the blades under high temperature and high pressure.
Surface treatment: such as coating and anodizing treatment to improve the wear resistance and corrosion resistance of the blades.
