chemical corrosion test

Chemical property testing: salt spray test of materials, corrosion test of stainless steel.

化学性能测试：材料的盐雾试验、不锈钢腐蚀试验等。

The test showed that, the acid phosphite with high chemical activity has excellent extreme-pressure anti-wear property but heat oxidation stability, anti-corrosion and anti-rust properties are poor;

试验说明化学活性很高的酸性亚磷酸酯有很好的极压抗磨性，但热氧化安定性、抗腐蚀性、防锈性不好；

The failure cause of the tubing was studied by macro and micro analysis, physical and chemical properties testing, X-ray energy spectrum analysis and stimulated corrosion test.

通过宏观和微观分析、理化性能检验、X射线衍射和模拟试验，对腐蚀油管进行了失效分析。
