AISI 430 stainless steel is an attractive material to be used in the healthcare industry, particularly as a sensor due to its low cost, corrosion resistance, as well as being Ni-free. AISI 430 was evaluated in an artificial sweat solution with the presence of Escherichia coli, and Staphylococcus aureus. Surface microbial analyses did not reveal colonization of bacteria on metallic surfaces, even when bacteria adhesion was investigated in a Müeller-Hinton solution. However, by electrochemical techniques, the AISI 430 surfaces demonstrated clear signs of corrosion mainly in a sterile medium after two weeks of exposure.

大肠杆菌和金黄色葡萄球菌存在下AISI 430不锈钢的腐蚀分析

AISI 430不锈钢是一种有吸引力的材料，可用于医疗保健行业，特别是由于其成本低，耐腐蚀且不含镍而特别适合用作传感器。在大肠杆菌和金黄色葡萄球菌的人工汗液中对AISI 430进行了评价。即使在Müeller-Hinton溶液中研究了细菌的粘附性，表面微生物分析也没有揭示细菌在金属表面的定殖。但是，通过电化学技术，AISI 430表面暴露了两周后，主要在无菌介质中显示出明显的腐蚀迹象。
