Which metal is electroplated on bathroom fittings ?
Chromium metal is electroplated on bathroom fittings. It has shiny appearance, does not corrode easily and resists scratches. So that is why it is used in electroplating.Get more news about Metal Tile Electroplating,you can vist our website!
Any company with a data center knows the importance of mitigating failure risks and maintaining an environment that promotes efficiency and uptime. From temperature monitoring to layout design, many factors can contribute to outages and failures. Disruptions can lead to lost time and data, but if you’re diligent, you can reduce the potential for failure before it occurs. However, there are some risks you may not know that apply to your data center until you observe the symptoms.
Zinc whiskers are one of these hazards. You may not know you’re dealing with them — or even what they are — until you begin to have problems around your data center. Learning about the causes and symptoms of zinc whiskers early on will help you identify the potential issue before your center suffers damage. Our guide will walk you through what zinc whiskers are, why they’re a security risk, how to properly diagnose the problem and what you can do to prevent and resolve the issue.
Zinc whiskers are crystals that form on the surfaces of steel items that have been electroplated with zinc. When it comes to steel specifically, the zinc plating helps protect it from rusting. Without the protective surface, it would be susceptible to the moisture from the room climate and cooling systems. But while the zinc prevents one problem, its presence in a data center can result in others.
The electroplating process causes a significant amount of molecular stress. Zinc overlay is an excellent barrier for preventing corrosion, but the passivation puts the zinc under consistent compression and stress. To relieve the pressure, the zinc may expand outwards, which forms microscopic filaments on the outer surface of these plates. These filaments grow over time, resulting in whiskers you can just barely observe with the naked eye.
While zinc whiskers are a more common problem in older data centers, they aren’t exclusively found there. They can form on any zinc electroplated metal surface. For data centers, this can mean the plenum sides of raised floor tiles, pedestals, stringers, cable and runway trays and other infrastructural supports. They’re common on wood core, composite wood core and concrete core tiles.
If your data center uses a raised floor HVAC system and has older floor tiles, you may run into issues caused by zinc whiskers. When the tiles are left without replacement or proper sealing, zinc whiskers can grow for years without disturbance.
Unfortunately, there’s no way to prevent them or stop growth by changing environmental conditions. They continue to lengthen regardless of humidity, temperature or any other outside factors. Their existence depends solely on the molecular makeup of the metal, meaning if your tiles or infrastructure includes steel electroplated with zinc, you’re at a high risk of experiencing problems related to zinc whiskers.
