The long range objectives of the investigation are 1 to identify the size and shape of the eroded particle, 2 analyze the mechanisms that produce these particles, and 3 to develop methods through which the erosion phenomena may be identified and prevented. Using the ASTM standard vibratory equipment, cavitation erosion tests were conducted on annealed SAE 52100 bearing steel and aluminum 1100-F in SAE 10W non-detergent lubricating oil and distilled water in addition to some preliminary other material fluid combinations. Specialized techniques for isolating and mounting the eroded particles were developed. The analysis of these particles was conducted by use of a specially built bichromatic light microscope, an electron probe micro-analyzer, and a scanning electron microscope.
