“…Examples of laboratory based corrosion tests are simulated environmental and salt-spray cabinet corrosion test. These laboratory tests must be able to keep the corrosion mechanism identical to the field corrosion tests [8][9][10]. Results of accelerated corrosion tests on the waste-gated adjustable and fixed end-links are reported in this paper.…”

A turbocharger which has been mounted to a heavy duty automotive diesel engine can be subjected to various aggressive environments and a range of temperatures varying from ambient to 670°C. Extreme operating environments and temperatures can initiate corrosion leading to the degradation of the components. The present research evaluates corrosion resistance of the Zinc coated and Stainless Steel waste-gate end-links based on accelerated corrosion and dust particles test, using an Environmental Test Rig. Samples were exposed to the tests for 504 hours. Images of the specimens were captured to record corrosion build-up and its progression on the surfaces during the exposure time. These results were then used to evaluate the corrosion resistance ability of both, Zinc coated Fixed and Stainless Steel Adjustable End-Links. Accumulation of corrosion and the build-up of salt deposits were observed on both End-Links during/after the experiments.

“…With time, the impact defect can even influence the corrosion of the sound coated portions at the vicinity of the defect. It is reported that once the corrosion is instigated on steel panel protected by an organic paint system, growing blisters appear on the intact portions followed by rapid deterioration [3,4].…”

“…In the work of Schmidt, Shaw, Sikora, Shaw, and Laliberte [3], the impedance at the lowest frequency was used to evaluate the corrosion protection performance at the defect and intact sites. The areas for examining the defect and sound portions were controlled using specialized conducting agar cells.…”

A method utilizing divided steel plates was used to investigate the corrosion of coated steel plates with impact defect while continuously submerged in 3% NaCl solution. The polarization behavior of circular divided steel plates was first compared to that of undivided ones. Half-cell potential and polarization resistance results show similar trend in divided and undivided form especially at the later stages of exposure. The method of using circular divided steel plates was then used to monitor the macrocell as well as microcell corrosion in coated steel plates induced with defect. The test results show that the defect causes macrocell corrosion to occur between the defect and sound portions. The impact defect also caused the reduction in the polarization resistance and consequently higher microcell corrosion at the neighbouring sound coated portions.
