摘要
利用高压水射流对HT250表面涂层进行清洗,采用Matlab软件统计图像像素的手段,研究不同移动速度、清洗压力及靶距条件下对涂层去除率的影响。通过Design Expert软件进行方案设计,拟合试验数据进行回归方程及建立响应面模型。研究结果表明:当移动速度为1 mm/s、清洗压力为15 MPa、靶距为208 mm时涂层清洗效果最优,在80 mm清洗轨迹上的清洗面积可达15.78 cm^2。
HT250 surface coating was removed by high-pressure waterjet. The decoating rates under different traverse speeds, cleaning pressures and target distances were studied by counting image pixels with Matlab. With the experiment scheme designed by the software Design Expert, the experimental data were fitted and the response surface models were built. The results show that the traverse speed of 1 mm/s, cleaning pressure of 15 MPa and the standoff distance of 208 mm are found to be the optimum. The decoating area along 80 mm of cleaning trajectory can reach 15.78 cm^2.
