Abstract
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.
Keywords: accelerated corrosion, turbocharger, end-links, extreme
environment.
