Quarry 2 Floor Tile

These are surface profiles of quarry 2 rough flooring. The quarry 1 (0T01881P, Daltile, Dallas, TX, USA) and quarry 2 (01 010 SM 1, Summitville, OH, USA) were commercial tiles, where the full composition was a trade secret, but they were known to include 15-25 wt% quartz, and quarry 2 also included abrasive grits on the surface, presumably to improve slip resistance. There are 30 profiles generated from image analysis and measured by SEM. 10 profiles are from 250X magnification, 10 profiles are from 5000X magnification, and 10 profiles are from 100kX magnification. There are also 6 profiles measured by stylus profilometry.

本数据集收录2号采石场粗面地砖的表面轮廓测量数据。1号采石场（产品编号0T01881P，品牌Daltile，美国得克萨斯州达拉斯市）与2号采石场（产品编号01 010 SM 1，品牌Summitville，美国俄亥俄州萨米特维尔市）的产品均为商用瓷砖，其完整成分属于商业机密，但已知二者均含有15~25 wt%的石英；其中2号采石场的瓷砖表面还覆有磨料颗粒，推测用以提升防滑性能。本次数据集共包含30组经图像分析生成、由扫描电子显微镜（Scanning Electron Microscope，SEM）测得的表面轮廓数据，其中10组对应250倍放大倍率，10组对应5000倍放大倍率，剩余10组对应10万倍放大倍率。另有6组表面轮廓数据通过触针式轮廓测量法测得。
