Abstract

Phosphor copper is often used to manufacture various shapes of parts, such as nuts, bolts, washers, etc., for connecting and fixing mechanical parts. In the process of coal mining and conveying, it is necessary to relieve environmental pressure by spraying dust reduction. Coal dust combines with fine water droplets to form coal slurry, which adheres and stays on mechanical equipment for a long time, causing structural corrosion, economic losses, and even safety accidents. In order to study the natural corrosion of phosphorus copper in coal slurry water, static immersion test under room temperature environment was used, and the morphology and chemical composition of the sample surface after immersion were analyzed by scanning electron microscopy and X-ray energy dispersive spectroscopy. The results showed that the corrosion products of phosphor copper were agglomerated nanoparticles in coal slurry water, and many carbon elements were left on the surface. In addition, the corrosion resistance, corrosion process and corrosion mechanism of phosphor copper in coal slurry water environment are discussed, which provide a research basis for the corrosion protection of metals in coal slurry water.
