研制了一种新型表面处理系统（ih - fpp系统），该系统结合了感应加热和细颗粒强化机。在室温、400℃、600℃和900℃条件下，用Cr颗粒对结构钢盘进行FPP处理。通过SEM、EDX和XRD对表面进行表征后，利用计算机驱动的恒电位器进行了三电极腐蚀测试。在室温、400°C和600°C下处理的样品没有明显差异。然而，在900°C处理的样品中，观察到更高的耐腐蚀性，几乎与FPP处理的不锈钢（SUS316L）相同。这是由于Cr扩散层覆盖了相对光滑的氧化表面，阻止了3%NaCl环境下的腐蚀反应。
A new surface treatment system (IH-FPPsystem) combined with an induction heating and a fine particle peening machine were developed. FPP treatments were carried out on structural steel discs by using Cr shot particle at room temperature, 400°C, 600°C and 900°C. After characterizing the surfaces by SEM, EDX and XRD, corrosion tests were performed by a three electrode method using a computer driven potentiostat. No noticeable differences were observed on the specimen treated at RT, 400°C and 600°C. In the case of the specimen treated at 900°C, however, higher corrosion resistance which is almost the same as FPP treated stainless steel (SUS316L) was observed. This was because Cr diffused layer covered with relatively smooth oxidized surface prevented a corrosion reaction in 3%NaCl environment.
