Azoting of the piston of the rod of the oil cylinder

Azoting of the piston of the rod of the oil cylinder- This is the process of heat treatment, designed to increase wear resistance and corrosion resistance of surfaces. It includes saturation of the surface with nitrogen at high temperatures, which leads to the formation of a solid nitrogen layer. This layer significantly increases the service life of components working in high loads and friction conditions. Learn more about the advantages and the application of this process in our article.

What is nitrogen and why is it necessary for pistons, rods and cylinders?

Azoting- This is the process of diffusion saturation of the metal surface with nitrogen. It is used to improve mechanical properties, such as hardness, wear resistance, fatigue strength and corrosion resistance. In the context of pistons, rods and cylinders working in oil,AzotingHe plays a key role in extending their service life and ensuring reliable work.

Advantages of nitrogening the piston of the rod of the oil cylinder

Increased wear resistance

AzotingSignificantly increases the hardness of the surface, making it more resistant to wear. This is especially important for pistons and rods that are subjected to constant friction against the cylinder wall.

Increased corrosion resistance

The nitrogen layer protects the metal from corrosion caused by the effects of oil, combustion products and other aggressive media. This prevents the formation of rust and increases the service life of parts.

An increase in fatigue strength

AzotingCreates compressive stresses in the surface layer, which increases resistance to fatigue destruction. This allows pistons, rods and cylinders to withstand higher loads and vibrations.

Spring reduction

The nitrogenous surface has a low friction coefficient, which reduces energy loss and improves the efficiency of the engine or hydraulic system.

Nitrogen process: Stages and features

ProcessnitrogenIncludes several stages:

1. Surface preparation:Cleaning and degreasing parts.
2. Heat:The details are heated in a special furnace to a temperature of 500-600 ° C.
3. Azoting:A nitrogenous environment (ammonia or other nitrogen -containing gases) is supplied to the furnace, which decomposes on the surface of the metal, saturating it with nitrogen.
4. Cooling:The details are slowly cooled in the furnace or in the air.
5. Finish processing:If necessary, polishing or other types of finish processing is carried out.

There are various methodsnitrogenincluding gasAzoting, ionicAzotingAnd liquidAzoting. Each method has its advantages and disadvantages, and the choice depends on the specific requirements for details.

Application of nitrogen in various industries

AzotingIt is widely used in various industries, including:

• Automobile industry:Pistons, rods, valves, gears.
• Mechanical engineering:Walls, gears, gear wheels, guides.
• Aviation industry:Details of engines, chassis, hydraulic cylinders.
• Oil and gas industry:Worm tools, pumps, valves.

The choice of the optimal nitrogen method

The choice of the optimal methodnitrogenDepends on several factors, including:

• Part material:Various materials require different parametersnitrogen.
• The required depth of the nitrogen layer:The depth of the layer affects the hardness and wear resistance of the surface.
• The required size accuracy:Some methodsnitrogenThey can cause deformation of parts.
• Production volume:Automated methods are more suitable for large -scale productionnitrogen.

Examples of application of nitrogening piston of the cylinder rod

Consider an example of applicationnitrogenIn the hydraulic cylinder:

Task:Increase the service life of the rod of a hydraulic cylinder operating under high humidity and pollution.

Solution: AzotingThe surface of the rod made it possible to increase its corrosion resistance and wear resistance, which significantly increased the life of the hydraulic cylinder.

Technical characteristics and nitrogen standards

ProcessnitrogenIt is regulated by various standards, such as:

• GOST 25286-82: Azoting. General technical requirements.
• ISO 4957: 2018:Instrumental steel.
• ASTM A962/A962M:Standard specification for general requirements for steel fasteners, bolts, studs, screws and nuts.

It is important to comply with these standards to guarantee quality and reliabilitynitrogenousdetails.
