Based on this knowledge, various modifications of silver-based coatings with markedly increased wear resistance have been developed, and a calculation model for predicting connector lifetime has been formulated. Investigations on silver-coated electrical contacts with increased wear resistance show extended lifetimes in fretting wear and fretting corrosion tests, and the calculation model with various modified coating materials can be validated. However, contacts with very high wear-resistant coatings fail earlier than the specific wear coefficient and the calculation model prediction suggest.\r\nThe in-depth investigation of the coating material and the wear scar revealed the reasons for this unexpectedly shorter lifetime. The high wear resistance of modified silver coatings is achieved by increased micro-hardness. Both coatings with coating materials of high hardness and high thickness can lead to longer lifetimes under fretting load. However, increased fretting cycles can also cause fatigue and electrical contacts can fail due to delamination of the surface coating caused by fretting fatigue, and this delamination can lead to a sudden exposure of the base material, thus enabling its corrosion.\r\nTherefore, both wear resistance and fatigue resistance should be increased in order to achieve a long lifetime of electrical contacts under fretting load." article_number: '205971' article_type: original author: - first_name: Jian full_name: Song, Jian id: '5297' last_name: Song - first_name: 'Soeren ' full_name: 'Tuelling, Soeren ' last_name: Tuelling - first_name: Jonas full_name: Hengstler, Jonas last_name: Hengstler citation: ama: 'Song J, Tuelling S, Hengstler J.

However, increasing performance requirements (e.g., operation at elevated temperatures) and regulatory restrictions are prompting a reassessment of lubricant selection. In this study, the influence of three lubricants (one oil and two greases), operating temperature (room temperature and 130°C), and applied volume (low, medium and high volume) on electrical contact resistance (ECR) and coefficient of friction (CoF) is investigated by means of fretting wear tests on silver-plated contacts. The results show that unlubricated silver contacts exhibit a longer stable phase at 130 °C than at room temperature. For lubricated contacts, service life is influenced by both temperature and lubricant volume. Certain lubricants demonstrate earlier fail at room temperature than at elevated temperatures. The findings highlight the importance of careful selection and optimization of lubricants for electrical connectors under varying environmental conditions. author: - first_name: Michael full_name: Blauth, Michael id: '49095' last_name: Blauth - first_name: Sören full_name: Tülling, Sören id: '71422' last_name: Tülling - first_name: Jian full_name: Song, Jian id: '5297' last_name: Song citation: ama: Blauth M, Tülling S, Song J.

Micro motions as well as vibrations lead to fretting wear, which can result in wear through of the protective coating. If this layer is worn through, the non-noble layer underneath is exposed, resulting in the occurrence of fretting corrosion with further relative motion. This leads to an increased electrical contact resistance (ECR) and can cause the contact to fail. Increasing the hardness of the coating material can reduce the wear and in turn increase contacts’ lifetime. The micro hardness, wear and lifetime of contacts with modified hard silver coatings are investigated in fretting wear and corrosion tests and the results compared to a conventional silver coating. Since one of the modifications shows a significant reduction in wear and hence improvement in lifetime, further analysis with SEM and FIB is conducted in order to identify the key mechanisms leading to this improvement. With a further increase in lifetime however, fatigue as well as delamination of the coating are revealed to be of high relevance. Both can be main causes of electrical contact failure under fretting load. In general, at lower number of cycles, increased micro hardness has the greatest effect on lifetime and wear while at the higher number of cycles, fatigue is observed to be the dominant failure mechanism. author: - first_name: Roman full_name: Probst, Roman id: '69156' last_name: Probst - first_name: Jian full_name: Song, Jian id: '5297' last_name: Song citation: ama: Probst R, Song J.

Silver is a promising plating material because of a good balance between performance and costs. The conventional silver plating is soft; therefore, a thick silver plating should be used to prevent the wear through during the operation. In order to enhance the wear resistance and prolong the lifetime of the silver plating, silver platings are modified by co-depositing nanoparticles with a core/shell structure into the silver matrix. A novel method to prepare the Ag (shell)@Al 2 O 3 (core) nanoparticles by galvanic process is introduced in this paper. The influence of fabrication parameters in the galvanic process such as the concentration of silver nitrate solution and the plating voltage on the silver content in the Ag@Al 2 O 3 nanoparticles is investigated. Afterwards, different concentrations of core/shell nanoparticles are co-deposited into the silver plating to study the effect of nanoparticles on the microhardness, microstructure and the lifetime of the silver plating. As a result, the microhardness and the lifetime of the silver plating are significantly improved and a favorable nanoparticle concentration exists for the longest lifetime. Moreover, the mechanism of the lifetime improvement is determined. author: - first_name: Haomiao full_name: Yuan, Haomiao id: '61860' last_name: Yuan - first_name: Roman full_name: Probst, Roman id: '69156' last_name: Probst - first_name: Jian full_name: Song, Jian id: '5297' last_name: Song citation: ama: Yuan H, Probst R, Song J.

In order to guarantee a high reliability of the system, the lifetime of the electrical contacts should be very long. Thus, it is of great importance to understand the failure mechanism and then to predict the lifetime of the electrical contacts. For the applications under high thermal and/or mechanical loads, noble plating is a good choice, considering its inertness to oxidation. For noble plating, one of the most critical failure mechanisms is the fretting wear. Wear debris generated in the contact area, acting as the third bodies, will greatly influence the further wear behavior and electrical performance. In this study, the state of the art regarding third bodies is firstly reviewed, and then the influence of the third bodies on the wear and electrical performance is investigated, from the aspects of lifetime and the element distributions in contact area. Finally, an example of prediction of the wear of noble plating is shown with the consideration of the third bodies. Based on this study, by involving the third bodies, the wear of noble plating can be predicted with a higher accuracy. article_number: '77' author: - first_name: Haomiao full_name: Yuan, Haomiao id: '61860' last_name: Yuan - first_name: Jian full_name: Song, Jian id: '5297' last_name: Song citation: ama: Yuan H, Song J.

The purpose of this study is to develop an analytical model which describes the electricalthermal behaviour of electrical contact systems. Established mechanical, electrical, thermal and contact physical relations are combined to design the analytical model. Differential equations with appropriate boundary conditions are used to solve the heating problem. The various parts of an electrical connector represent separate subsystems. The geometry, the material properties and the heat transfer coefficients for the contact system, the terminal clamp and the wire have been taken into account. These different subsystems have been connected to obtain the overall temperature distribution. In order to verify the analytical model, contact systems made of three copper alloys with different electrical and thermal properties are investigated experimentally at various current loads. It was shown that the analytical model can predict the temperature rise for simple geometry well. Using the analytical model several parameters can be easily changed. Moreover, the main influencing factors and their relationships can be identified directly on the equations.
