Figure 10 The actual width of scratches and the change of width-to-depth ratio of scratches <br>Consider the elastic recovery phenomenon that occurs on the surface of the material, so calculate the actual width of scratches. It is found that as the particle size of the abrasive particles increases, the actual width of the scratch gradually increases, but the tendency to increase becomes relatively small. The ratio of scratch width to depth is used to describe the degree of scratch damage. It was found that the width-to-depth ratio of the scratches increased as the particle size of the abrasive particles increased. When the scratch depth is greater, the aspect ratio is smaller.

Figure 10 Scratch Actual Width and Scratch Depth Ratio Change Chart<br>The actual width of the scratch is calculated, taking into account the elastic reply occurring on the surface of the material. It is found that with the increase of the particle size, the actual width of the scratch gradually increases, but the trend of increasing is relatively smaller. The degree of scratch damage is described by the ratio of width to depth of the scratch. The depth ratio of scratches was found to increase with the increase in the size of the grain. When the depth of the scratch is larger, the wider depth is smaller than the smaller.

Fig. 10 change of actual scratch width and scratch width depth ratio<br>Considering the elastic recovery on the surface of the material, the actual width of the scratch is calculated. It is found that with the increase of abrasive particle size, the actual scratch width increases gradually, but the increasing trend is relatively smaller. The ratio of scratch width to depth is used to describe the degree of scratch damage. It is found that the width depth ratio of scratches increases with the increase of abrasive particle size. The larger the depth of the scratch, the smaller the aspect ratio<br>
