Best 10 Washers To Prevent Galvanic Corrosion Reviews and Buying Guide 2023

If you’re looking for ways to prevent galvanic corrosion, washers are a great option. Washers work by providing a barrier between two surfaces that are prone to corrosion. This barrier can be made of rubber, plastic, or metal.

What is Galvanic Corrosion?

Washers To Prevent Galvanic Corrosion
Galvanic corrosion, also called bimetallic corrosion, dissolution, corrosion, or more accurately dissimplant corrosion, is an electrochemical process whereby a metal corrodes when in contact with a different type of metal, in the presence of an electrolyte, such as water or moisture. An electrolyte can be a liquid, solid, or gaseous substance. A example, moisture is a solid electrolyte, and the atmospheric gases are gaseous electrolytes.The two different metals are are electrically connected form a galvanic couple, and galvanic corrosion results when one of the metals in the couple corrodes. The corroding metal becomes an anode and goes into solution, and the other metal becomes a cathode and is deposited on the surface of the cathode. In some cases both metals will corrode, and dissolve ions from both anode and cathode go into solution.

For are six types of galvanic corrosion that can occur:
* dissimilar metal corrosion
* crevice corrosion
* pitting corrosion (also called cavity corrosion)
* intergranular corrosion
* filiform corrosion
* uniform corrosion.

If a copper pipe is connected to an iron pipe, the iron pipe will be the cathode and will corrode. This is because iron has a higher oxidation potential than copper. This is because anode, and will not corrode. Instead, copper ions will diffuse out of the copper pipe and be deposited on the iron pipe. A is deposited on the iron pipe while iron is dissolved into water solution.

In the typical commercial system, water tanks are used to storing hot water. The steel is heated using electric oror elements. When the water is heated, water dissolves into the water and forms a layer on the bottom of the steel tank. This causes pitting corrosion and the steel tank. As shown becomes more anode, it is into solution.
steel tank eventually fails because of corrosion.

A The typical commercial system, steel tanks are used for storing hot water. The water is heated using electrical resistor elements that are made of aluminum. When the water is heated, the aluminum conducts electricity, and the water he the tank acts as an electrolyte. When current passes through the aluminum element, the water corrodes because it is the anode, and goes into solution. As aluminum goes into solution, the tank begins to leak and causing a loss of pressure in hot water.

What is Galvanic Corrosion?

Galvanic corrosion occurs when two metals of different electrochemical activity come in contact through an electrolyte. A simple example is the corrosion of the zinc coating on a galvanized steel washer due to electrical contact with aluminum parts or fasteners. In this case, the aluminum is more active, erode than the steel washer.

This situation that the aluminum atoms are stripped away from the washer and sent into the electrolyte (water) solution. This happens because aluminum metal easier the zinc atoms more than the zinc atoms dissires the aluminum atoms. Eventually, the aluminum atoms are forced to the surface of the aluminum washer.

In a nutshell, the more electrochemical active metal diss forced to dissires the less electrochemically active metal. Diss will

Galvanic corrosion is most common than many people realize. It is cause serious problems for manufacturers equipment and plumbing systems, and it needs to be prevented whenever possible. Let. corrosion inhibitor is often used to prevent galvanic corrosion.

The best way to prevent galvanic corrosion is by using a corrosion inhibitor on both the more anode and cathode. Corrosion inhibitors work by making the water less conductive by electric currents. The water becomes a better electrical insulator, preventing the electrons from flowing between the anode and cathode. Because electrons can’t flow freely between the two metals, the corrosion process is stopped.

Galvanic corrosion inhibitors can be found in many different forms. Some are liquid chemicals that you simply pump into your system, while others are solid chemicals that you apply directly to the surface of the metals. Other types of corrosion inhibitors include greases and gels as well as powders. Each inhibitor is used depends on what type of environment you’ll be using the equipment in, as well as your expected water chemistry.

Galvanic corrosion is cause serious problems for industrial equipment and plumbing systems, so it’s important to understand how it occurs and how to prevent it. By using a corrosion inhibitor, you can ensure that your equipment will stay in good condition for a years to come.

Can Galvanic Corrosion Be Prevented?

Galvanic corrosion can be prevented by ins addingulating metals from contact with each other, eliminating electrolytes from the connection region and using metals with different electrode potentials to prevent these metals from coming in contact.

How to Protect Your Metal Parts From Galvanic Corrosion

Galvanic corrosion occurs when two dissimilar metals are immersed in an electrolyte, As the current flows between the metals, the less noble metal (the one whose electrode potential is higher) corrodes. In this case, the anode materialolves into the electrolyte and metal ions enter the solution, while the cathode does not dissolve and the metal remains.

The rate of galvanic corrosion is on the area ratio of the anode to the cathode, the distance between the two, the temperature, the conductivity of the electrolyte, and the difference in potential between the two metals. Typically, the larger the difference in the nobility of the two metals, the shorter the time before the faster the galvanic corrosion, the smaller the difference in electrode potential, the longer the time required. The higher the temperature, the faster the corrosion process.

How to Choose the Right Washers to Prevent Galvanic Corrosion?

Choosing the right washers for your fastener application is crucial for preventing galvanic corrosion. The wrong pair could lead to failure and damage to the surrounding surface. Here are some considerations for choosing right washers:

1. Material
You need to choose a washer that has similar properties as the component fastener. For example, if you are using a stainless steel bolt and nut, then use a stainless steel washer that it will be more compatible and won’t have high electrical resistance. Carbon
2. Corrosion resistance
Galvanic corrosion happens caused by a chemical reaction between two different metals. It usually to the loss of material and surface contamination the area where the two metals are in contact. So minimize galvanic corrosion, you should choose a washer made from the material that is corrosion-resistant and electrically conductive. Otherwise materials include brass, stainless steel, silver, gold, aluminum, and copper.
3. Hole size
The hole size should be bigger than the diameter of the bolt so that the bolt/nut can fit through it. For example, if you are using a 5/16″ bolt, then you need a washer that has a hole size between than ½″.
4. Tightness
You need a washer with the correct thickness to form a right fit. If the thickness of the washer is too thin, then the washer won’t be tight enough to form a good seal. On the other hand, if the washer is too thick, then you won’t be able to get the bolt to fit through the washer.
