(AISI 420: Cr 13%, C 0.3%) in the annealed condition, with hardness of 2.4 GPa; 2) Cemented carbide (WC 94%, Co 6%) with hardness of 15 GPa; 3) Chromium-plated low-carbon steel (EN32b: C 0.15%, Mn 0.75......
pollution caused by the excess discharge of hexavalent chromium and total chromium in the industry, bismuth ferrite activated was used by visible light to reduce highly toxic and highly migratory hexavalent chromium to trivalent chromium with low toxicity and low mobility. The hydrothermal method was used to prepare magnetic bismuth ferrite. Meantime, the effects of key factors such as different......
