目的:研究三亚海域不同海区环境因素和腐蚀性差异。方法对三亚海域亚龙湾和红塘湾两海区的自然环境因素数据和海生物种类及生长速度进行比较分析,并对钢、不锈钢、铝合金和铜合金等4种典型金属材料在两海区的腐蚀性能进行对比研究。结果两海区的海水环境因素除盐度外差别不大,随月份的变化规律一致。由于钛合金在海水中具有良好的耐蚀性,因此选用PVC和钛合金分别代表非金属材料和金属材料研究两海区海生物附着规律,结果发现两海区附着海生物的数量和种类差别较大,钛合金板的海生物附着量明显多于PVC板。四种典型金属材料在红塘湾和亚龙湾相同区带条件下的腐蚀速率相差很小。结论两海区环境因素及腐蚀性差异不大,具有较好相关性。
目的:研究三亞海域不同海區環境因素和腐蝕性差異。方法對三亞海域亞龍灣和紅塘灣兩海區的自然環境因素數據和海生物種類及生長速度進行比較分析,併對鋼、不鏽鋼、鋁閤金和銅閤金等4種典型金屬材料在兩海區的腐蝕性能進行對比研究。結果兩海區的海水環境因素除鹽度外差彆不大,隨月份的變化規律一緻。由于鈦閤金在海水中具有良好的耐蝕性,因此選用PVC和鈦閤金分彆代錶非金屬材料和金屬材料研究兩海區海生物附著規律,結果髮現兩海區附著海生物的數量和種類差彆較大,鈦閤金闆的海生物附著量明顯多于PVC闆。四種典型金屬材料在紅塘灣和亞龍灣相同區帶條件下的腐蝕速率相差很小。結論兩海區環境因素及腐蝕性差異不大,具有較好相關性。

ABSTRACT:Objective To study differences in environment factors and corrosivity in different Sanya sea areas. Methods The natural environment factors in Hongtang Bay were compared with those in Yalong Bay. Furthermore, the species and the growth speed of marine organisms were also compared. Four kinds of typical metals and alloys, namely, steel, stainless steel, aluminum alloy and copper were compared for corrosivity in the two sea areas. Results It showed that sea water environment factors except salinity in the two sea areas were in good coincidence as well as their variations within months. Ti and PVC were chosen as the representatives of metal and nonmetal materials respectively to study the laws of biofouling, considering the excellent corrosion resistance of Ti in seawater. It showed that the speciesand amount of marine organisms adhered were quite different in the two sea areas, and the adhesion amount of marine organisms on the Ti plate was larger than that on the PVC plate. Corrosion rates of the four kinds of typical metals and alloys differed very little in the same zone conditions in the two areas. Conclusion Environment factors and corrosivity in the two sea areas have little differences and there is good relativity between environment factors and corrosivity.
