3D 参数在摩擦学研究中非常重要，其中许多参数与表面操作性能密切相关。气缸套表面的表征是使用 3D 粗糙度参数的一个很好的例子。标准 ISO 25178-2:2012 定义了新参数，保留了一些旧参数，尽管作为等效的 3D 后继参数呈现。例如“k”系列就是这种情况：S-pk、S-vk 和 S-k。本文对 S-pk 与新体积参数 V-mp 之间的关系进行了分析，结果表明，标准中规定的将 S-pk 指定为核心表面上方突出峰的平均高度是不正确的。还建议应保留 S-k，但新的体积参数通过其与“k 系列”的关系，可以丢弃 S-pk 和 S-vk。 (C) 2014 Elsevier Inc. 保留所有权利。
3D parameters are important in tribological studies and many of them show strong correlation with surface operational performance. Characterization of cylinder liner surfaces is a good example of the use of 3D roughness parameters. Standard ISO 25178-2:2012 defines new parameters retaining some of the old ones, even though presented as their equivalent 3D successors. That is the case for instance of the "k" series: S-pk, S-vk and S-k. This paper covers an analysis of the relationship between S-pk and the new volume parameter V-mp where it is shown that it is not correct to designate S-pk as the average height of the protruding peaks above the core surface as stated in the standard. It is also suggested that S-k should be maintained but that the new volume parameters, through their relationship to the "k series", make it possible to discard S-pk and S-vk. (C) 2014 Elsevier Inc.
