| 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 species and 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. |
