Dr. Rosenbloom’s expertise is in metallurgical engineering and electrochemical testing of medical devices. Dr. Rosenbloom conducts failure analysis investigations in order to determine the cause of failure in a variety of industrial settings, as well as for biomedical applications. She has developed expertise in analyzing a broad range of corrosion mechanisms (e.g., stress corrosion cracking, formicary corrosion, galvanic corrosion, underdeposit corrosion, pitting, erosion corrosion, cavitation, and general corrosion), as well mechanical failures (e.g., fatigue, overload, wear, and failure due to manufacturing defects). Her work has focused on the failure modes of a number of metallic materials including steels, copper and copper-based alloys, aluminum alloys, and nickel-based alloys. She consults in a variety of industries including HVAC, petrochemical processing and refining, food handling, pharmaceutical, biomedical implant devices, and chemical processing.
Dr. Rosenbloom also consults on the topic of biocompatibility of medical implants with regard to their corrosion resistance in the body. She has extensive experience in assessing resistance to pitting corrosion per ASTM F 2129, galvanic corrosion per ASTM G 71, metal ion leaching in long-term corrosion tests, as well as in designing customized testing protocols. She has developed expertise in the corrosion behavior of a broad range of implant materials such as stainless steel, nitinol, titanium alloys, and cobalt-chromium based alloys. Dr. Rosenbloom also has experience in conducting risk assessments and evaluating potential release of material into the body from corroding or potentially corroding devices.
Dr. Rosenbloom participated in identifying corrosion research grand challenges and in developing a national strategy for fundamental corrosion research while serving on an expert panel for the National Academy of Sciences/National Research Council.
Dr. Rosenbloom has experience testifying at deposition and serving as an expert witness.
Prior to joining Exponent, Dr. Rosenbloom was the Principal Metallurgical Engineer for Corrosion Testing Laboratories, Inc. in Newark, Delaware.
