※ Equipment Use
High-frequency inverter pulsed ion nitriding furnace is a kind of equipment used for metal surface treatment, mainly used to improve the surface hardness, wear resistance and corrosion resistance of metal parts. Through high-frequency inverter technology and pulse power supply, glow discharge is used to produce nitrogen ions in a vacuum or low pressure environment, so that nitrogen ions penetrate into the metal surface to form a nitriding layer.
※ Main Features:
·1. High-frequency inverter technology: Through the high-frequency inverter power supply, the current and voltage can be accurately controlled, improve energy utilization efficiency and reduce energy consumption.
·2. Pulse power supply: pulse power supply can avoid overheating of the workpiece surface, reduce deformation, and improve the uniformity and quality of the nitriding layer.
·3. Glow discharge: In a vacuum or low pressure environment, nitrogen ions are generated by glow discharge, which react with the metal surface to form a nitriding layer.
·4. Temperature control: The equipment is usually equipped with a precise temperature control system to ensure the temperature stability of the nitriding process and avoid overheating or uneven temperature of the workpiece.
·5. Automatic control: Modern high frequency inverter pulse ion nitriding furnace is usually equipped with automatic control system, which can realize the automatic adjustment and monitoring of process parameters.
※ Application field:
·- Machinery manufacturing: used for surface treatment of gear, bearing, mold and other parts to improve their wear resistance and service life.
·- Automotive industry: used for nitriding of engine parts, transmission systems and other components to improve their anti-fatigue and anti-corrosion properties.
·- Aerospace: used for surface treatment of aircraft engine parts, turbine blades and other key components to improve their high temperature performance and corrosion resistance.
·- Tool manufacturing: used for surface treatment of tools such as cutting tools and molds to improve their hardness and wear resistance.
※ Advantages:
·- High efficiency and energy saving: high frequency inverter technology can improve energy utilization efficiency and reduce energy consumption.
·- Good uniformity: Pulsed power supply and precise temperature control ensure the uniformity of the nitriding layer.
·- Environmental protection: Compared with the traditional nitriding process, the ion nitriding furnace is carried out in a vacuum or low pressure environment, reducing the emission of harmful gases.
※ Precautions:
·- Process parameter control: the quality and performance of the nitriding layer are closely related to process parameters (such as temperature, time, gas ratio, etc.) and need to be strictly controlled.
·- Equipment maintenance: regularly maintain the equipment to ensure its normal operation and avoid equipment faults affecting the nitriding effect.
