High - frequency Inverter Pulse Ion Nitriding Furnace

High - frequency Inverter Pulse Ion Nitriding Furnace

Equipment Usage

Main Characteristics

1. High - frequency Inverter Technology: Through the high - frequency inverter power supply, the current and voltage can be accurately controlled, which improves the energy utilization efficiency and reduces energy consumption.
2. Pulse Power Supply: The pulse power supply can avoid overheating of the workpiece surface, reduce deformation, and at the same time improve the uniformity and quality of the nitride layer.
3. Glow Discharge: In a vacuum or low - pressure environment, nitrogen ions are generated by glow discharge, and the nitrogen ions react with the metal surface to form a nitride layer.
4. Temperature Control: The equipment is usually equipped with a precise temperature control system to ensure the stability of the temperature during the nitriding process and avoid overheating or uneven temperature of the workpiece.
5. Automation Control: Modern high - frequency inverter pulse ion nitriding furnaces are usually equipped with an automation control system, which can realize the automatic adjustment and monitoring of process parameters.

Application Fields

• Mechanical Manufacturing: It is used for the surface treatment of parts such as gears, bearings and molds to improve their wear resistance and service life.
• Automobile Industry: It is used for the nitriding treatment of components such as engine parts and transmission systems to improve their fatigue resistance and corrosion resistance.
• Aerospace: It is used for the surface treatment of key components such as aircraft engine parts and turbine blades to improve their high - temperature performance and corrosion resistance.
• Tool Manufacturing: It is used for the surface treatment of tools such as cutting tools and molds to improve their hardness and wear resistance.

Advantages

• High - efficiency and Energy - saving: The high - frequency inverter technology can improve the energy utilization efficiency and reduce energy consumption.
• Good Uniformity: The pulse power supply and precise temperature control ensure the uniformity of the nitride layer.
• Environmental - friendly: Compared with the traditional nitriding process, the ion nitriding furnace operates in a vacuum or low - pressure environment, reducing the emission of harmful gases.

Precautions

• Process Parameter Control: The quality and performance of the nitride layer are closely related to the process parameters (such as temperature, time, gas ratio, etc.), which need to be strictly controlled.
• Equipment Maintenance: Regularly maintain the equipment to ensure its normal operation and avoid affecting the nitriding effect due to equipment failure.

Technical Parameters

• Output voltage: Continuously adjustable from 0 to 1000V.
• Maximum output peak current: Different for different models, ranging from 30A to 460A.
• Frequency: Usually 20kHz or above, and some can reach hundreds of kHz.
• Ultimate vacuum degree: Usually can reach 6.7Pa. A low ultimate vacuum degree can reduce gas impurities in the furnace and create a pure environment for ion nitriding.
