After each run the microscopic observations of the sample surfaces were done and their brightness was registered and automatically calculated by the programme MultiScan. An essence of the method is like this: each pixel on the picture of the sample surface is changed to black if its brightness is lower than an assumed threshold. In the opposite case it was changed to white. Pixel brightness ranged from 0 to 255. Deformation was linked to the black area fraction in the binary image (in %). The method cannot be used when the material pieces are extracted out from the surface layer or when the plastic deformations overlap. These make the surface morphology smoother and may lead to an increase in its brightness. Observations were carried out at the areas (1.8mm×2mm) of high-intensity cavitation erosion and low-intensity cavitation erosion, which were defined due to an assumption—as the areas where the mean depth of penetration rates at the reference material were 0.4 m/min and 0.1 m

之后,每一个运行的显微观察的样品表面做了和他们的亮度是登记,并自动计算方案multiscan 。一个本质的方法是这样的:每个像素对图片的样品表面是改为黑色,如果它的亮度是低于一假定的门槛。在相反的情况下,改为白色。像素的亮度范围从0到255 。变形是联系在一起的黑色部分地区,在二值图像( % ) 。该方法不能用来当材料件提取出来,从表层时,或塑料变形,重叠。这些使表面形貌的顺畅,并可能导致增加了在其亮度。意见进行了在区( 1.8毫米× 2毫米)高强度的空蚀和低强度的空蚀,其中的定义,由于一个假设-作为地方的平均深度的渗透率在参考材料分别为0.4米/分钟和0.1米/分钟,分别。空蚀坑和indentations负责的损失,表面的亮度。侵蚀的表现材料所定义的损失,其亮度η (减少,反射率)下的空负荷。相对量化材料的耐磨性是做直接比较的η不同的样本。这种方法确定的空阻力,让近似结果,该方法的基础上坑计数,这是承认为量化汽蚀损伤在发病潜伏期间的侵蚀(如[ 17 ] ) 。一个不准确的评估, η价值观包括在该实验点描绘。空蚀实验构成的一系列运行和条件不同,可以在每一个系列,由于可能改变流体流量的参数和一段有限的时间内稳定的空化的电线。但是,应该有任何影响,对价值η为参考样品,受到相同的空化impingements 。有区别的利率平滑的表面侵蚀,由于粒子的提取或塑料株各种样本,并导致增加在其表面的亮度是一个来源,可能出现的错误。
