研究了聚氨酯分别在含石英砂的清水、聚丙烯酰胺（ＰＡＭ）溶液和氢氧化钠溶液三种介质条件下，磨粒侵蚀过程中所发生的表面物理效应和表面化学效应。利用扫描电子显微镜（ＳＥＭ）、光电子能谱仪（ＸＰＳ）和傅立叶表面红外仪（ＦＴ－ＩＲ－ＡＴＲ）对聚氨酯在磨损前后的表面形貌、元素组成、结合能和官能团作了分析。发现聚氨酯磨粒侵蚀的物理效应是运动颗粒对材料表面的微切削、材料的高疲劳破坏以及塑性断裂，而表面化学效应主要有分子链断裂、热降解、水解和氧化降解。
The surface physical effects and surface chemical effects of the abrasives during the erosive process of the abrasive were studied under the conditions of water, polyacrylamide (PAM) solution and sodium hydroxide solution. The surface morphology, elemental composition, binding energy and functional groups of polyurethane before and after wear were analyzed by scanning electron microscopy (SEM), photoelectron spectroscopy (XPS) and Fourier transform infrared spectroscopy (FT-IR-ATR) It is found that the physical effect of polyurethane abrasive erosion is the micro-cutting of material surface by moving particles, the high fatigue failure and plastic fracture of the material, while the surface chemical effects mainly include molecular chain breakage, thermal degradation, hydrolysis and oxidative degradation.
