Nitriding is a proven process that offers remarkable results when it comes to enhancing the durability and performance of steel components. Nitriding services, which are offered by Alpha Detroit Heat Treatment, play a vital role in achieving effective nitrogen diffusion into steel, creating a hardened surface layer that can withstand wear, corrosion, and high-temperature environments.

The Working Principles of Nitriding

The process of nitriding introduces nitrogen into the surface of workpieces, especially steel parts. It alters the composition of the steel itself, unlike traditional surface treatments that involve coatings or plating. The result of this process is a surface layer with enhanced properties, which include increased hardness, improved wear resistance, and better corrosion resistance.

Typically performed in specialised equipment called nitriding furnaces, the key to nitriding’s success lies in carefully controlled temperatures, time, and gas atmosphere. The following is a set of steps involved in the process of nitriding.

• Preparation: The first step is preparation. It involves cleaning and placing the steel components that will be subjected to nitriding in the nitriding furnace.

• Heating: The furnace is then heated to the desired temperature, which can range from 500°C to 1200°C, depending on the specific steel and desired properties of the clients.

• Nitrogen Introduction: Ammonia gas or NH3 is subsequently introduced into the furnace. The ammonia dissociates at high temperatures, releasing nitrogen atoms.

• Diffusion: Nitrogen atoms diffuse into the steel’s surface, forming nitrides.

• Post-Treatment: In some cases, post-treatments like polishing or oxidation must be carried out to fine-tune the surface finish and further enhance properties.

Alpha Detroit’s Nitriding Services

We, at Alpha Detroit Heat Treatment, can carry out nitriding services to diffuse nitrogen to steel components. Our team offer these services so we can improve their overall performance.

Through these services, we can increase the hardness of nitride surfaces, providing resistance to wear and abrasion. Nitriding services also allow us to improve the fatigue strength of steel components, making them suitable for high-stress applications. Even the corrosion resistance of these workpieces can be improved through our nitriding process.

Nitriding also lets us maintain the shape and size of steel components as the process does not cause distortion or dimensional changes. It likewise improves the high-temperature performance of the workpieces. All these added benefits of nitriding allow nitride parts to boast a longer service life, reducing the need for costly replacements and maintenance.

Our nitriding services find applications across various industries, including automotive, aerospace, tool manufacturing, and more. Common components that benefit from nitriding include crankshafts, gears, camshafts, injection moulds, and extrusion dies.

Nitriding is a remarkable surface treatment that enhances the properties of steel components, making them more durable and resistant to wear, corrosion, and high temperatures. When performed by Alpha Detroit Heat Treatment, nitriding services unlock the full potential of this process, providing solutions that meet the demanding and specific requirements of a variety of industries.
