Refinement of the Vibratory Cavitation Erosion Test for the Screening of Diesel Cooling System Corrosion Inhibitors

Source

A modification of the ASTM Vibratory Cavitation Erosion Test (G 32-77) is proposed for the evaluation of a cooling system corrosion inhibitor's ability to reduce the deterioration of the water-side of diesel engine cylinder liners. The procedure combines the effects of cavitation and corrosion, and, therefore, better simulates the pitting attack on cast iron cylinder liners. Results from the modified test correlate well with laboratory engine results and field experience. Further areas of investigation are suggested, although it is recommended that the general test procedure be considered for adoption as an ASTM test method for diesel engine coolant corrosion inhibitors.
