Introduction
Hard chrome plated rods are a type of metal rod that has been coated with a thin layer of chromium. This coating provides the rods with several desirable properties, including:
- Increased hardness
- Improved wear resistance
- Enhanced corrosion resistance
- Reduced friction
As a result of these properties, hard chrome plated rods suppliers are widely used in a variety of applications, including:
- Hydraulic cylinders
- Pneumatic cylinders
- Linear guides
- Pump shafts
- Valve stems
Properties of Hard Chrome Plated Rods
The following are some of the key properties of hard chrome plated rods:
- Hardness: Hard chrome plating can increase the hardness of a steel rod by up to 70 Rockwell C (HRC). This makes them ideal for applications where wear and tear is a major concern.
- Wear resistance: Hard chrome plating is highly resistant to wear and abrasion. This makes them well-suited for use in applications where there is a lot of friction, such as hydraulic cylinders and pneumatic cylinders.
- Corrosion resistance: Hard chrome plating provides excellent corrosion resistance. This makes them ideal for use in applications where they will be exposed to harsh environments, such as saltwater or chemicals.
- Reduced friction: Hard chrome plating has a low coefficient of friction. This makes them ideal for use in applications where smooth, low-friction movement is required, such as linear guides.
Applications of Hard Chrome Plated Rods
Hard chrome plated rods are used in a wide variety of applications, including:
- Hydraulic cylinders: Hard chrome plated rods are used in hydraulic cylinders to provide a wear-resistant surface for the piston to slide against.
- Pneumatic cylinders: Hard chrome plated rods are used in pneumatic cylinders to provide a wear-resistant surface for the piston to slide against.
- Linear guides: Hard chrome plated rods are used in linear guides to provide a smooth, low-friction surface for the bearing to slide against.
- Pump shafts: Hard chrome plated rods are used in pump shafts to provide a wear-resistant surface for the seals to slide against.
- Valve stems: Hard chrome plated rods are used in valve stems to provide a wear-resistant surface for the packing to slide against.
Manufacturing Process for Hard Chrome Plated Rods
The manufacturing process for hard chrome plated rods typically involves the following steps:
- Cleaning: The rods are first cleaned to remove any dirt, grease, or other contaminants.
- Pickling: The rods are then pickled in an acid solution to remove any rust or scale.
- Rinsing: The rods are rinsed to remove any acid residue.
- Plating: The rods are then plated with a thin layer of chromium.
- Finishing: The rods are finally finished to the desired surface roughness.
Conclusion
Hard chrome plated rods are a versatile and valuable product that is used in a wide variety of applications. Their unique properties make them ideal for use in applications where wear and tear, corrosion, and friction are major concerns.
