To investigate the friction behaviors of elastomer and polyacetal writing tips sliding on various textured glass surfaces, the influences of the pitch size and height of sub-millimeter to millimeter sized texture on friction were examined via reciprocating friction tests. The friction coefficients of each writing tip could be systematically varied by changing the pitch and height of the texture. These changes in friction were based on the relationship between the convex-concave shapes and the contact parts of the writing tip, and hence, influence the adhesive, abrasive, and deformation frictions. By inducing a surface texture with a pitch smaller than the contact area of the writing tip, the friction coefficient could be reduced effectively. By inducing a surface texture with a larger height, the friction coefficient of the elastomer could be increased due to deformation friction. These behaviors indicate the possibility of controlling the friction by changing the parameters such as the pitch and height of the textured glass surfaces.
为了研究弹性体和聚缩醛笔尖在各种纹理玻璃表面上滑动时的摩擦行为，通过往复摩擦试验研究了亚毫米到毫米尺寸纹理的节距尺寸和高度对摩擦的影响。通过改变纹理的节距和高度，可以系统地改变每个笔尖的摩擦系数。这些摩擦变化是基于凹凸形状与笔尖接触部分之间的关系，因此会影响粘着摩擦、磨料摩擦和变形摩擦。通过诱导节距小于笔尖接触面积的表面纹理，可以有效降低摩擦系数。通过诱导高度较大的表面纹理，由于变形摩擦，弹性体的摩擦系数会增加。这些行为表明通过改变纹理玻璃表面的节距和高度等参数来控制摩擦的可能性。
