Plated metal tarnishes refers to the process in which metal is treated with metal plating that chemically deposits silver onto its surface. It is an important step in many industries, including metalworking, construction, and shipbuilding.

One of the key benefits of plating metal is that it can help protect metals from corrosion, which is caused by the exposure to moisture and oxygen. This makes plating metal particularly useful for applications where a high level of corrosion resistance is required, such as in vehicles, pipelines, and shipbuilding.
The process of plating metal involves the following steps:
1. The metal is typically heated until it reaches the desired temperature and has a high melting point. This temperature range is called the melting point.
2. The melted metal is then stripped off using tools or equipment to remove any foreign materials or impurities. This is known as the electroplating stage.
3. The remaining material is passivated by applying a treatment that helps it to absorb a specific amount of silver. The process of passingivating is done at the beginning of the electroplating stage and involves mixing the molten metal with a sugar solution that binds silver to the metal’s surface.
4. After the chemical transformation is complete, the metal is processed further to create final products. This may include casting, welding, oring.
There are several types of plating metal, including hard-shining and tempering. Hard-shining is a process that involves placing a layer of heavy silver on the surface of the metal to reduce its response to changes in temperature. Tempering is a process that involves slowly removing the layer of silver and leaving it on the metal to heal itself.
The process of plating metal can be both effective and dangerous, and there are risks involved. For example, if not done carefully, the process can result in the formation of non-chromium silver that can be harmful to humans. Additionally, if the treatment is performed in excess of the recommended level, the exposed metal may become thinner and more prone to corrosion.

Overall, plating metal tarnishes offers several benefits over traditional methods of processing metal, such as improving its durability, reducing its risk of corrosion, and increasing its ability to withstand high temperatures. However, it is important to be cautious when performing this process and to ensure that all necessary safety measures are in place.
