Dr. Sun has long been committed to applied fundamental research in corrosion protection and friction materials. Addressing the technical bottlenecks and critical demands of key core equipment, she conducts comprehensive studies integrating fundamental theories of surface/interface corrosion and wear in mechanical components, the design of high-strength and high-toughness materials, and precision prediction models for service lifespan. Her research delves into the oxidation mechanisms and damage protection principles of materials in typical service environments at the molecular level.
