水工钢结构表面喷镀金属层防腐蚀,能够得到较长期的保护效果。但喷镀到铜结构表面上的金属均是较贵的有色金属,因此喷镀金属层厚度的选择至关重要。喷镀厚了造成浪费,反之达不到预期的保护效果。针对喷镀金属层保护膜厚度质量问题,运用统计分析的原理可以较全面的评价喷镀金属层厚度的质量。并且较为直观容易分析。 Hydraulic steel surface metallized metal layer anti-corrosion, can be more long-term protective effect. However, the metal sprayed onto the surface of the copper structure is a more expensive non-ferrous metal, so the choice of the thickness of the sprayed metal layer is of crucial importance. Spraying thick waste, on the contrary fail to reach the expected protective effect. In view of the quality of the protective film thickness of the sprayed metal layer, the principle of statistical analysis can be more comprehensive evaluation of the quality of the thickness of the sprayed metal layer. And more intuitive and easy to analyze.
