为获得镀锌层耐大气腐蚀数据,在江津、碾子山、海南岛三个试验站进行为期十年的自然环境试验。现已进行了五年,初步取得了一批可靠性数据。本文就五年试验结果进行总结。试验条件1.试样的选择和制备试样共分三类:①零件:②零件底材制作试片;③以A_3钢为底材制作的试片。零件按生产实际的几何形状,大小,尺寸进行,零件底材和A_3钢制作的试片尺寸均为100×50mm。各类试样均按各供试单位大生产工艺或特定的试验工艺进行制作。
In order to obtain the data of atmospheric corrosion resistance of galvanized coating, a ten-year natural environment test was carried out in Jiangjin, Nianzishan and Hainan Island. It has been going on for five years and initially obtained a number of reliability data. This article summarizes the results of the five-year trial. Test conditions 1 sample selection and preparation of the sample is divided into three categories: ① parts: ② parts substrate production test strips; ③ A_3 steel as a substrate for the production of the test piece. Parts according to the actual production of the geometry, size, size, parts of the substrate and A_3 steel test piece size is 100 × 50mm. All kinds of samples according to the test unit for the production process or a specific test technology for production.
