在金刚砂砂浆中。用旋转圆盘式冲刷腐蚀试验机研究了流速、含砂量、砂粒粒径等环境参数对ＳＥＢＦ－２型熔融结合环氧粉末涂层冲蚀特性的影响，并观察了涂层形貌实验结果表明：涂层的冲蚀率（Ｅ）与流速（Ｖ）、含砂量（Ｃ）、砂粒粒径（Ｄ）之间服从幂指数关系： Ｅ∝Ｖｎ１Ｃｎ２Ｄｎ３，ｎ１、ｎ２、ｎ３ 的相对大小表明，流速为主要影响因素，其次为砂粒粒径，而含砂量的影响相对较小；在本文的实验条件下，临界流速约为 ６ｍ／ｓ，涂层的第一临界粒径约为 ８０μｍ；第一临界粒径约为 ４１０μｍ．
In the emery mortar. The influence of environmental parameters such as flow rate, sand content and grit size on the erosion behavior of SEBF-2 fused epoxy powder coating was investigated by rotary disc erosion testing machine. The experimental results of coating morphology It shows that the relationship between erosion rate (E) and flow rate (V), sand content (C) and sand particle size (D) follows the power exponent relationship: the relative sizes of EαVn1Cn2Dn3, n1, n2 and n3 , The flow rate is the main influencing factor, followed by the sand particle size, but the influence of sand content is relatively small. Under the experimental conditions, the critical flow velocity is about 6m / s and the first critical particle size of the coating is about 80μm. The first critical particle size is about 410 μm.
