What are the differences between nickel-plated rollers and chrome-plated rollers?

In order to improve the performance of rollers, nickel plating and chromium plating are often very popular surface treatments for rollers. "Which one is better, nickel-plated roller or chrome-plated roller, has become a topic of debate. This article will focus on comparing these two rollers from all aspects.

Durability

Due to their higher hardness, both chrome-plated rollers and nickel-plated rollers are popular. They usually have very good durability. However, the chemical plating process makes the nickel layer more adherent to the surface of the roller. Therefore, under long-term use, the nickel-plated roller is more durable than the chrome-plated roller, and the service life of the nickel-plated roller is longer than that of the chrome-plated roller.

Corrosion resistance

One of the improved properties of drums after chrome or nickel plating is corrosion resistance. Both nickel-plated rollers and chrome-plated rollers have good corrosion resistance. The coating on their surfaces can improve corrosion resistance, making them suitable for use in environments such as acid and alkali solutions. While both types of drums are corrosion-resistant, studies have shown that electroless nickel plating is superior in corrosion resistance. Electroless nickel plating can form a more uniform coating on the surface of the roller, effectively preventing corrosion on the roller surface. Nickel-plated rollers and chrome-plated rollers are both good choices. If corrosion resistance is a priority, you can choose a nickel-plated roller.

Hardness

Chrome or nickel plating of the drum will help reduce wear. Usually hard chrome plating is used for chrome plating on the surface of the drum. Hard chrome plating is known for its hardness. After chromium plating, the Rockwell C hardness of the roller surface is between 68-72, while the surface hardness of the nickel-plated roller is slightly lower than that of the chrome-plated roller.

In general, chrome plating and nickel plating of rollers can protect equipment and parts from wear. If hardness is given top priority in the selection process of these two rollers, you can choose chrome-plated rollers.
