How does ZKL Series 650℃ Liquid Nitriding Furnace improve the wear resistance of metal parts?

1. The importance of wear resistance in modern manufacturing
1.1 The wear resistance of metal parts
In modern manufacturing, the wear resistance of metal parts is an important factor that determines their service life, work efficiency and cost-effectiveness. With the continuous advancement of industrialization, the working conditions of machinery and equipment are becoming more and more severe, and parts are facing greater friction, impact and heat load. Especially in the automotive, aerospace, energy and heavy machinery industries, the wear resistance of parts directly affects the stability, reliability and safety of equipment.
For example, engine parts, gears, bearings, etc. are frequently exposed to high temperature, high pressure and high-speed friction. If the wear resistance is insufficient, it will lead to premature damage, work interruption and high maintenance costs. In order to extend the service life of these parts, improving their wear resistance has become a technical problem that the manufacturing industry urgently needs to solve.
1.2 The proposal and demand of ZKL Series 650℃ Liquid Nitriding Furnace
In order to improve the wear resistance of metal parts, ZKL Series 650℃ Liquid Nitriding Furnace came into being. Liquid nitriding is a treatment method that forms a layer of nitride on the metal surface through the nitriding process. Compared with traditional heat treatment methods, ZKL Series 650℃ Liquid Nitriding Furnace can better improve the surface hardness, wear resistance and corrosion resistance of parts. Liquid nitriding can not only improve the hardness and wear resistance of the metal surface, but also improve the fatigue performance and high temperature resistance of parts, thereby meeting the needs of modern industry for high-performance parts.

2. Basic principles and applications of ZKL Series 650℃ Liquid Nitriding Furnace
2.1 Overview of ZKL Series 650℃ Liquid Nitriding Furnace
ZKL Series 650℃ Liquid Nitriding Furnace is a technology that immerses metal parts in liquid nitrogen at high temperature to allow nitrogen to penetrate into the metal surface. This process is usually carried out at a high temperature of 650℃. Nitrogen atoms penetrate into the metal surface and react with metal atoms to form nitrides, such as iron nitride. This nitriding layer increases the surface hardness and wear resistance of the metal, while also improving the corrosion resistance and fatigue resistance of the parts.
Compared with gas nitriding and salt bath nitriding, ZKL Series 650℃ Liquid Nitriding Furnace has significant advantages: First, the liquid nitriding temperature is moderate, which can reduce the thermal deformation caused by high temperature; second, the nitriding layer is uniform during the liquid nitriding process, which can ensure the consistency of the surface hardness of the parts; third, the liquid nitriding process is precisely controlled, which can better meet the needs of modern precision manufacturing.
2.2 Technical advantages of liquid nitriding
Compared with traditional heat treatment technology, ZKL Series 650℃ Liquid Nitriding Furnace has significant advantages in many aspects:
High hardness: Liquid nitriding can form a high-hardness nitriding layer on the metal surface, making the parts more durable under friction, wear and other conditions.
High corrosion resistance: The nitriding layer can effectively prevent oxidation and corrosion of the metal surface. Especially in harsh environmental conditions, liquid nitriding can significantly extend the service life of parts.
High stability: Metal parts treated with liquid nitriding show strong thermal stability, can still maintain high hardness in high temperature environments, and adapt to more extreme working conditions.
Accuracy and uniformity: ZKL Series 650℃ Liquid Nitriding Furnace can provide a uniform nitriding layer, and the temperature control is precise, which can maximize the dimensional accuracy and shape stability of parts.
2.3 Scope of application of liquid nitriding
ZKL Series 650℃ Liquid Nitriding Furnace is widely used in automobiles, aerospace, metallurgy, heavy machinery and other fields, especially in the following parts:
Automotive parts: such as engine parts, bearings, gears, suspension systems, etc., liquid nitriding can effectively improve their wear resistance and fatigue resistance.
Aerospace parts: engine parts, turbine blades, etc. working in high temperature and high pressure environments, liquid nitriding can extend their working life.
Heavy machinery parts: such as transmission parts in mining machinery and construction equipment, etc., liquid nitriding can effectively improve their impact resistance and wear resistance.

3. How does liquid nitriding improve the wear resistance of metal parts?
3.1 Increase the surface hardness of metals
The core function of liquid nitriding is to form nitrides through nitrogen atoms and metal surfaces, thereby increasing the surface hardness of metals. The nitriding layer is usually composed of multiple layers, and the surface hardness can reach 70-75HRC, which is much higher than the untreated metal surface. This high hardness can effectively resist wear and extend the service life of parts in high friction environments.
For example, the surface hardness of automobile engine gears and bearings treated with liquid nitriding is significantly improved, which can withstand higher workloads and reduce failures and maintenance costs.
3.2 Improve the fatigue resistance of parts
Liquid nitriding not only improves the surface hardness of parts, but also improves the fatigue resistance of parts by generating compressive stress. The compressive stress layer can effectively delay the generation and expansion of microcracks, thereby improving the fatigue resistance of metal parts under repeated loading. Especially in the automotive, aerospace and other industries, parts need to withstand high-frequency load changes, and the fatigue resistance of liquid nitriding is particularly important.
3.3 Enhanced corrosion resistance
The nitride layer generated during the liquid nitriding process has extremely high density, which forms an effective barrier on the metal surface to prevent chemical reactions such as oxidation and corrosion. This is especially important for parts working in wet and high-salt environments, such as parts in ships, offshore platforms, chemical equipment and other fields. The metal surface treated with liquid nitriding can resist the erosion of corrosive media such as salt water and acidic solutions, greatly extending the service life of the parts.
3.4 Improvement of other properties
Liquid nitriding can also improve the heat resistance of metal parts. Especially in high temperature environments, the hardness of metals usually decreases, resulting in a significant reduction in their wear resistance. The metal surface treated with liquid nitriding can maintain a high hardness under high temperature conditions, thereby ensuring that the parts can still maintain excellent wear resistance and performance under high temperature and high friction working conditions.

4. Effect of Liquid Nitriding on Different Metal Parts
4.1 Liquid Nitriding Treatment of Steel
Steel is the main application object of ZKL Series 650℃ Liquid Nitriding Furnace.

Especially in the fields of automobile and machinery manufacturing, steel parts treated with liquid nitriding usually have longer service life and lower maintenance costs.
4.2 Liquid Nitriding Treatment of Aluminum Alloy and Copper Alloy
Although the nitriding property of aluminum alloy and copper alloy is relatively poor, by adjusting the parameters of ZKL Series 650℃ Liquid Nitriding Furnace, these metal surfaces can also form a nitrided layer to improve their wear resistance and corrosion resistance. Especially in the fields of aviation and electronic products, the nitrided layer of aluminum alloy and copper alloy can greatly improve their oxidation resistance.
4.3 Liquid nitriding treatment of titanium alloys and other high-strength materials
Titanium alloys and other high-strength alloy materials usually have high toughness and high-temperature resistance. Liquid nitriding treatment can improve their surface hardness and wear resistance without affecting their original performance. They are particularly suitable for high-precision and high-requirement fields such as aerospace and medical equipment.
