Carbon or similar material may be used in the construction of the counterface, which is that part which comes into contact with the seal face. Elastomers, such as Viton or nitrile rubber, are used for the sealing elements to create a flexible and leak-proof barrier. Springs or other mechanical elements are typically made from stainless steel or other high-strength alloys to maintain the necessary pressure on the seal faces. Each component is designed to withstand the operational demands and ensure a reliable seal.
What materials are used for mechanical seal faces?
Mechanical seal faces are designed from materials known to be hard wearing and generally resistant to wear and tear. Some of the most frequently utilized materials are ceramic, tungsten carbide and carbon. The faces are made from ceramics that offer high cutting hardness and excellent abrasion resistant, which enables them to be used in applications where high pressure and high heat are incorporated. Tungsten carbide faces are highly durable and suitable to come in contact with abrasive fluids. Carbon faces are also desirable because they help minimize the level of friction that occurs in usage and this leads to minimum wear of the surfaces.
The material used depends on the function of the welded seal and the types of fluids which may be in contact with the welded seal. All of the materials are properly chosen so that mechanical seal will provide its best performance and durability.
What are mechanical seals made of in automotive applications?
Mechanical seal automotive application can operate in high temperature, high pressure conditions and chemically hostile environments. These seals often have faces which have carbon, ceramic, or Tungsten carbide on them as the facing material. Carbon is used due to its ability to withstand high pressures as well as due to it being self lubricating. That is why material such as ceramic or tungsten carbide are used because they are very hard and can resist wear. The secondary sealing elements usually come in the form of elastomers like the Viton or EPDM because they can adapt to the automotive environment.
Additionally, metal parts of the seal are often made from stainless steel or other high-strength alloys to ensure durability. The materials are selected to ensure reliable performance and longevity in the demanding conditions of automotive systems.
