Alumina nanostructured coating for corrosion protection of 316L stainless steel
نویسندگان
چکیده مقاله:
Nanostructured alumina thin films were coated on stainless steel by Sol-Gel dip coating method. In order to prevent crack formation, Al2O3 films were kept in a solvent bath immediately after coating to reduce the rate of drying. Effects of calcination temperature and withdrawal speed on structural properties were analyzed using XRD and SEM. Topography and thickness of coatings were analyzed by AFM. Effects of the above parameters on anticorrosion performance of coats have been evaluated through electrochemical polarization technique. The results indicated that the optimum calcination temperature to achieve the best corrosion protection was 400ºC. The thickness of one time coating with 1mm/s withdrawal speed was about 146 nm.

متن کاملMicro abrasion-corrosion of AISI 316L stainless steel
In this study, the synergistic effects of abrasion and corrosion on AISI 316L stainless steel have been investigated using a micro-abrasion test rig. A series of results from abrasioncorrosion tests conducted using the micro-abrasion rig are presented. AISI 316L stainless steel has been studied under both pure abrasion and abrasion-corrosion conditions simulated by either distilled water or 3.5...
متن کاملOrganic-inorganic sol-gel coating for corrosion protection of stainless steel
One of the most effective corrosion control techniques is the electrical isolation of the anode from the cathode [1, 2]. The chromium oxide (Cr2O3) passivation layer formed on the surface of stainless steel in oxidizing environments is one example. This is the main reason for the durability and corrosion resistance behavior of this particular metal [2, 3]. A more generic approach to enhance cor...
متن کاملLiquid Metal Corrosion of 316L Stainless Steel, 410 Stainless Steel, and 1015 Carbon Steel in a Molten Zinc Bath
Corrosion tests of 1015 low-carbon steel and two stainless steels (410 and 316L) were conducted in a pure zinc bath (99.98 wt pct Zn) in order to better understand the reaction mechanisms that occur during the degradation of submerged hardware at industrial general (batch) galvanizing operations. Through this testing, it was found that, in general, 316L stainless steel showed the best dissoluti...
