“…The vibration frequency ranges from 10 to 2000 Hz [6]. The operating environmental conditions of the connectors are conducive to the occurrence of corrosion, which promotes faster wear of the components [7]. For this reason, the materials from which the connectors are made should be resistant to high humidity, high and low temperatures and the presence of acid oxides in the air, including nitrogen oxides and sulfur oxides [3].…”

Automotive electrical connectors are the essential components of a wiring harness. They are typically made of copper, which has excellent electrical conductivity. Due to the limited corrosion resistance of pure copper, connectors are often coated with other metals. In this paper, the qualities of coatings made of gold and tin are investigated and compared. The samples were examined by a metallographic microscope and scanning electron microscope (SEM). The examination revealed uneven thickness, delamination of the coatings, and issues with the preparation of the core material for coating. Numerous burrs and irregularities were observed. Selected samples were examined in salt solution to test their corrosion resistance. Even though gold is a noble metal and its electrochemical potential is higher, the tin coating was more resistant to corrosion.

In paper the impact of intentionally chlorine-contaminated fuel on nitrogen oxides emission control elements in compression engine was described. The quality of fuel used is of key importance for the failure-free operation of the engine. Fuel contamination can occur mainly at the transport or storage stage.The main attention was paid to the EGR heat exchanger, which is used for exhaust gases recirculation, being one of the ways to reduce the emission of harmful NOx. The tests were conducted under laboratory conditions (research engine stand tests) in cycles consisting of four phases. The fuel used was intentionally contaminated with chlorine. The test was interrupted after 250 hours at the engine failure and deposits appearance at the EGR heat exchanger. Test results of chemical composition of deposits, analytical methods used and sources and the cause of deposits appearance were described in present paper.
