Predictive Model for Cut-Edge Corrosion of Galvanized Steels

The humid tropical climate parameters and airborne salinity are generally considered important factors affecting detrimental corrosion of zinc and its alloy coatings. To more thoroughly understand their corrosion performances, the five years weathering tests for zinc and Zn-Al galvanized steels in rural and coastal humid tropical areas were conducted. Corrosion rates and other performance characteristics of zinc and Zn-Al coated samples were determined and discussed in relation with climatic and environmental parameters. Behavior of the coatings in rural and coastal tropical conditions revealed a strong influence of time of wetness (TOW) and airborne salinity on corrosion rates. In both test conditions, the dependence of coating’s mass loss on exposure time shows that the corrosion process of zinc coatings mostly obeys the law of power model M = Atn. Corrosion is recorded considerably stronger in the coastal atmosphere containing higher chlorides. The laboratory observation in cut-edge area of zinc alloys coated steel was also conducted and their corrosion behavior was detailed in condition of chloride ions attack.

SummaryThe formation of hemostatic plugs were studied in the chick embryo through in vivo microscopy, in sections of hemostatic plugs and by measurements of primary bleeding time. Thrombocytes were found to be their only cellular constituent. Ability to form adequate hemostatic plugs appeared rather abruptly in embryos of stages 16-17 and coincided with an increase in thrombocyte precursors (stages III and IV).The thrombocytes initially adhere to the cut edge of the vessel. The extension of the hemostatic plug into the vessel lumen is a secondary step in plug development.

Local Fiber

Coffee edge-wicking testing was conducted on two groups of highly-sized paperboard manufactured at two mills with similar manufacturing processes, but with vastly different local fiber sources. Although the Hercules size test (HST) indicated similar internal size levels between the two types of board, the edge-wicking behavior was noticeably different. Analysis of fiber structure revealed that the board with more edge-wicking had fibers with thicker fiber walls, which kept the fiber lumen more open after pressing and drying on a paper machine. It was demonstrated that liquid penetration through voids between fibers in highly-sized paperboard was limited, because the fiber surface was well protected by the presence of sufficient sizing agent. Nevertheless, freshly exposed fiber walls and lumens at the cut edge of the sheet were not protected by sizing material, which facilitated edge-wicking. The correlation between fiber structure and edge-wicking behavior was highlighted in this work to inspire development of novel sizing strategies that protect the freshly cut edge of the sheet from edge-wicking.
