What are the primary environmental factors that contribute to corrosion in different materials?5 answersThe primary environmental factors influencing corrosion in various materials include temperature, humidity, SO2, Cl−, salinity, dissolved dioxide, pH, and water velocity. Factors like relative humidity, temperature, sulfur dioxide, and chloride play significant roles in atmospheric corrosion, with their increase correlating with higher corrosion rates. In marine environments, salinity, temperature, dissolved dioxide, pH, oxidation reduction potential, and water velocity collectively impact the corrosion process in complex ways. Additionally, the presence of akaganeite under natural conditions and the identification of lepidocrocite, goethite, and magnetite under both natural and artificial corrosion conditions highlight the diverse corrosion products formed under different environmental exposures. Understanding these factors is crucial for predicting corrosion rates, developing protective measures like organic coatings, and assessing the structural integrity of materials in various settings.
What are the mechanisms by which corrosion occurs at grain boundaries in stainless steel tanks?5 answersCorrosion at grain boundaries in stainless steel tanks can occur through various mechanisms. Grain boundary engineering (GBE) techniques aim to optimize grain boundary characteristics to enhance corrosion resistance. Studies suggest that the corrosion rate is significantly faster at polycrystalline grain boundaries compared to twin crystals and single crystals, with stress release promoting Fe atom dissolution and oxygen diffusion, leading to intergranular corrosion. Additionally, the presence of atmospheric chlorides from airborne sources is a key factor in initiating corrosion in stainless steel tanks, particularly in coastal areas, affecting both outer and inner tank surfaces. Understanding these mechanisms is crucial for developing strategies to mitigate corrosion in stainless steel tanks.
Does stainless steel corrode with carbonates?5 answersStainless steel can corrode when exposed to carbonates. The corrosion rate and mechanism depend on various factors such as the specific carbonate composition, gas environment, and exposure conditions. In some cases, the presence of carbonates can accelerate the corrosion of stainless steel, leading to the formation of porous scales. However, the corrosion resistance of stainless steel can be improved by using certain pretreatment methods or coatings. For example, in-situ corrosion pretreatment with N2-20%O2 gas can suppress the dissolution of corrosion products and enhance corrosion resistance. Additionally, the use of stainless steel reinforcement in chloride-contaminated concrete has been studied, and certain stainless steel alloys have shown good corrosion resistance even in carbonated concrete and harsh exposure conditions. Overall, the corrosion behavior of stainless steel in carbonates is influenced by various factors and can be mitigated through appropriate pretreatment or material selection.
What are the causes of alkaline corrosion of 316L stainless steel?5 answersThe causes of alkaline corrosion of 316L stainless steel include the presence of sulfur compounds such as sulfide and the acceleration of corrosion by cyanide. The medium's characteristics, such as the presence of chloride and phosphate salts, temperature, and pH, also contribute to the increased corrosion rate. Additionally, the microstructure and electrochemical behavior of 316L stainless steel can affect its corrosion resistance. Laser powder bed fusion (L-PBF) processed 316L stainless steel showed better electrochemical behavior and lower corrosion current density compared to the wrought counterpart in an alkaline solution. The presence of electroactive microorganisms in oral microbiota can also accelerate the corrosion of 316L stainless steel. The corrosion resistance of 316L stainless steel can be enhanced through various coating processes and additives.
Erosion-corrosion behavior of 304 and 316 stainless steel in the presence of different corrosive environments?5 answersThe erosion-corrosion behavior of 304 and 316 stainless steel in different corrosive environments has been studied in several papers. The corrosion resistance of 316L sintered stainless steel was investigated under a corrosive atmosphere, and it was found that weight and density increased with higher energy density (Ev). The corrosion behavior of 2205 duplex stainless steel was examined in gaseous environments with different relative humidity values, and it was observed that corrosion occurred under wet conditions with gas flushing, particularly at higher flow velocities. The tribo-corrosive wear of AISI 316 stainless steel was studied under high-speed jet impingement by a sand-liquid flow, and it was found that weight loss increased with time and impact angle, and erosion from flowing sea sand caused more weight loss than from silica sand. The corrosion behavior of Type 304L stainless steel in nitric acid with fluoride additions was investigated, and it was shown that fluoride accelerated anodic dissolution.

How does the corrosion threshold of 316L stainless steel in concrete vary with different environmental conditions?1 answersThe corrosion threshold of 316L stainless steel in concrete varies with different environmental conditions. The presence of chloride (Cl–) and thiosulfate (S2O32–) accelerates general corrosion, but the pitting resistance of additively manufactured (AM) 316L stainless steel is 4-6 times higher than that of the wrought sample, depending on the S2O32– concentration. The corrosion resistance of 316L stainless steel components manufactured with selective laser melting (SLM) technology is influenced by surface orientation, with the highest corrosion rate observed in the presence of H2SO4 solution. The corrosion behavior of 316L stainless steel in aqueous NaOH at elevated temperatures is characterized by parabolic weight loss and the formation of iron-oxy-hydroxide and nickel-oxide. The electrochemical performance of 316L stainless steel rebars in concrete is improved by the presence of fly ash up to 20 wt.%, but this trend is reversed at 25 wt.%.
