镀层厚度测量结果对比研究

Comparative Study on Metallic Coating Thickness Measurement Results

镀层是管壳抗腐蚀能力的重要部分,镀层厚度的测量准确性也成为人们关注的重点。采用SJ20129中规定的两种测量方法对某管壳进行镀覆层厚度的测量,将测量结果进行对比分析,并分析了误差产生的原因。

Metallic coating is an important component of the package’s ability to resistant to corrosion.Precision of the measurement results of metallic coating thickness also attract attention.Two methods provided in the standard SJ20129 were used to measure metallic coating thickness of a package,then a comparative analysis was done and the errors was analyzed.
