    Abstract

    The breaking load test was used for evaluating the effectiveness of a corrosion preventive compound to protect aluminum alloy 2024-T351 from stress corrosion cracking. This test determines the post-exposure fracture stress of smooth tensile coupons exposed to 3.5% NaCl alternate immersion while held at various stress levels. Three groups of specimens were examined: uncoated specimens, specimens coated before environmental exposure, and specimens coated after one day of exposure. Statistical procedures based on analysis of variance methods were used to analyze the data. This statistical methodology shows much promise as a general approach to analysis of breaking load test data.
