对1Cr18Ni9Ti不锈钢板进行喷淋蚀刻,分析蚀刻深度h、蚀刻初始尺寸D、蚀刻速率、侧蚀率之间关系。实验结果表明,h<0.4mm时,蚀刻深度、初始尺寸对蚀刻速率的影响不明显;h>0.4mm、D<0.5mm时,蚀刻速率随蚀刻深度的增加而减小,初始尺寸越小,减小趋势越明显;蚀刻深度与侧蚀率呈线性关系,而初始尺寸越大,蚀刻深度对侧蚀的影响就越小,并建立了三者之间的关系式。 1Cr18Ni9Ti stainless steel plate spray etching, analysis of the etching depth h, the initial size of the etching D, the etching rate, the relationship between the side eclipse rate. The experimental results show that when h <0.4mm, the etching depth and initial size have no significant effect on the etching rate. When h> 0.4mm and D <0.5mm, the etching rate decreases with the increase of etching depth. The smaller the initial size, The trend of decreasing is more obvious. The etching depth has a linear relationship with the side eclipse rate. The larger the initial size, the smaller the influence of the etching depth on the side eclipse, and the relationship between the three is established.
