What is the special significance of metal aviation plug plating

What is the special significance of aviation plug plating? Contact plating can not only protect the product surface, reduce the environment of its corrosion intrusion, increase durability and wear resistance, it can also help establish and maintain a stable impedance from the electrical properties. Specifically manifested in: 1, aviation plug plating anti-corrosion function: the first thing that should be considered is corrosion protection. Most of the contact shrapnel is made of copper alloy, and copper alloy in the typical working environment is susceptible to corrosion, of course, the plating material in its working environment must not be damaged (at least in the harmful range). As an important function of corrosion protection at the same time, the optimization of the interface is the selection of suitable contact plating material considerations. 2, aviation plug plating helps to improve the mechanical properties: parameters related to mechanical properties are mainly factors that affect the durability or wear of the plating, as well as the fit force. These factors to be considered, is in the same basic effect of two different views of the multi-point contact interface in the process of relative movement of cold welding share. The most important mechanical properties include hardness, ductility and coefficient of friction of the plating material. All these properties depend on the intrinsic properties of the plated material and the working process to which it is applied.3, aviation plug plating helps to improve the electrical performance: the optimization of electrical performance can be considered from the following aspects, namely, the control of the already existing and to be formed on the surface of the surface film located in the contact plating. One of the main needs of electrical performance is to establish and maintain a stable connector impedance. To accomplish this, a metallic contact interface is required to provide such inherent stability. Establishing such a contact interface requires a surface film that can either avoid or split during contact mating. These two different choices clarify the distinction between precious or rare metals and common metals.4. Characteristics of precious metal coatings used in aviation plugs: To varying degrees, precious metal coatings (such as gold, palladium, and their alloys) are intrinsically free to the surface film. For these coatings to produce interfacial metal contact is relatively simple, because it only needs to contact the surface of the concomitant in the fit when the movement. Usually this is easily achieved. In order to maintain the stability of the impedance of the contact interface, the design requirements should pay attention to maintain the contact surface noble metal to prevent the influence of external factors such as contaminants, the diffusion of the base metal, and contact wear.5, aviation plugs using common metal plating characteristics: common metal plating, especially tin or tin alloys, the performance of its natural covered with a layer of oxidized film. The role of the tin contact plating, because this layer of oxide is easy to be destroyed at the time of fit, so that the metal contact is easy to be established. The design requirement is to ensure that the oxide film breaks down when the connector is mated, and that the contact interface is not oxidized again during the lifetime of the electro-connecting adherent. Re-oxidizing corrosion, in the case of abrasion corrosion, is the dominant performance degradation mechanism for tin contact coatings. Silver contact coatings are better treated as common metal coatings because they are susceptible to corrosion by sulfides and chlorides. Nickel coatings are also commonly treated as common metals due to the formation of valve warps.-6, on the Evergrande electronic products network platform related to the introduction and sales of products briefly: Evergrande electronic products network - a professional agent / production / sales of all kinds of {connectors | wiring harness | wire and cable products }; if you have a related [connectors | wiring harness | wire and cable products] procurement / purchasing needs or would like to buy / to understand which connectors | harness | wire and cable products we can provide solutions, please contact the following Division I business personnel; If you have related [connectors | wire harness | wire and cable products] sales / resources and promotion needs, please click on the "¡¡ Business Cooperation ←" with the person to discuss!
