Cylinder liners are used in internal combustion engine and several other applications. With this article, we will tell and make you learn about the process that enhances wear resistance in engine cylinder liners.
With gas nitriding method, it is possible to improve the wear resistance of the cylinder liners. It is a thermochemical process in which the ferrous metal surface is added with nitrogen. This process is based on the nitrogen solubility in iron. Being one of the significant surface hardening techniques, nitriding is used for making aircraft, textile machines, bearings, and various automotive parts, including valves and piston rods.
Why Nitriding Process Is Used By Manufacturers?
As nitriding process does not require a phase change, steel retains its ferrite phase during the entire process. There is no such requirement of quenching; free cooling is done under nitriding process. It enhances the fatigue life and brings anti-galling properties and high surface hardness. This process is conducted at low temperatures unlike other case hardening techniques. Manufacturers are mostly relying on this technique as it is cost effective.
Gas Nitriding - It is a type of nitriding in which the nitriding surface to be developed over the component surface by using the nitrogen obtained by diffusing ammonia. The process is conducted inside a furnace by sustaining and maintaining the needed conditions. Required parameters are-
A cylinder liner needs to be washed by aqeous alkaline detergent or similar product. You need to clean it well to eliminate all contaminants to avoid side effects over nitriding layer.
Advantages Of Gas Nitriding Process

- Furnace temperature
- Gas flow
- Time
- Gas activity control
- Process chamber maintenance

Advantages Of Gas Nitriding Process
- This process is done at low temperature as compared to other techniques, including carbonitriding.
- There is no phase change when the process occurs; hence, no molecular size change happen
