摘要	The effects of multilayer sea sand particles of varying sizes and Shewanella algae (S. algae) on the corrosion behavior of 316 stainless steel (SS) were investigated. The findings reveal that in a sterile environment, sand hinders the diffusion of dissolved oxygen, thereby impeding the growth of the passive film and enhancing the corrosion of 316 SS. The promotion effect intensifies as the particle size of the sand decreases. In a non-sterile environment, in the absence of sand, S. algae accelerates the corrosion by consuming dissolved oxygen, and expediting the breakdown of passive film. The corrosion acceleration caused by S. algae is markedly greater than that induced by sand. When sand is present, it markedly reduces the effective attachment of S. algae, thereby mitigating the corrosion-accelerating effect of S. algae. Additionally, a reduction in sand particle size leads to a decrease in S. algae attachment and an enhancement in corrosion inhibition.
