作为湿法磷酸生产过程主要设备的料浆泵要受到合固体颗粒的酸性浆液的严重破坏，其寿命大大缩短为尽快弄清其腐蚀机理，以设计出适合此介质的不锈钢，本文研究２种不锈钢在模拟介质中的磨损腐蚀行为．
As the main equipment of wet-process phosphoric acid production, the slurry pump is severely damaged by the acidic slurry of solid particles and its life is shortened as soon as possible to find out its corrosion mechanism to design a stainless steel suitable for this medium. In this paper, two kinds of stainless steel Wear Corrosion behavior in simulated media.
