Abstract: This digital artefact documents the results of experiments in metals tribology. It is constructed strictly observing the FAIR data principles. The experiments test the reciprocation sliding of a 10-mm single-crystal sapphire sphere against a polycrystal (average size ~45 µm) copper base body. The range of normal loads is 0–4.5 N, the sliding velocity is always 0.5 mm/s, and the experiments are performed in ambient 50% RH atmosphere. How to work with this data: The files in this Zenodo record carry the metadata and descriptions associated with the experiments. They are serialized in RDF. All raw and processed data is collected into RO-Crates (10.3233/DS-210053), and are stored at institutional servers with the following addresses (these are also semantically linked using Zenodo's schema on the right): https://dx.doi.org/10.35097/1028 https://dx.doi.org/10.35097/1029 https://dx.doi.org/10.35097/1030 https://dx.doi.org/10.35097/1036 https://dx.doi.org/10.35097/1037 https://dx.doi.org/10.35097/1038 https://dx.doi.org/10.35097/1039 https://dx.doi.org/10.35097/1041 https://dx.doi.org/10.35097/1043 https://dx.doi.org/10.35097/1045 https://dx.doi.org/10.35097/1047 https://dx.doi.org/10.35097/1049 https://dx.doi.org/10.35097/1051 https://dx.doi.org/10.35097/1052 https://dx.doi.org/10.35097/1053 https://dx.doi.org/10.35097/1054 https://dx.doi.org/10.35097/1057 https://dx.doi.org/10.35097/1058 https://dx.doi.org/10.35097/1059 https://dx.doi.org/10.35097/1060 https://dx.doi.org/10.35097/1061 https://dx.doi.org/10.35097/1063 https://dx.doi.org/10.35097/1065 https://dx.doi.org/10.35097/1066 https://dx.doi.org/10.35097/1067 https://dx.doi.org/10.35097/1070 https://dx.doi.org/10.35097/1071 https://dx.doi.org/10.35097/1072 https://dx.doi.org/10.35097/1073 https://dx.doi.org/10.35097/1074 https://dx.doi.org/10.35097/1075 https://dx.doi.org/10.35097/1076 https://dx.doi.org/10.35097/1077 https://dx.doi.org/10.35097/1078 https://dx.doi.org/10.35097/1079 https://dx.doi.org/10.35097/1080 https://dx.doi.org/10.35097/1082 https://dx.doi.org/10.35097/1083 https://dx.doi.org/10.35097/1085 https://dx.doi.org/10.35097/1086 https://dx.doi.org/10.35097/1087 https://dx.doi.org/10.35097/1088 https://dx.doi.org/10.35097/1089 https://dx.doi.org/10.35097/1090 https://dx.doi.org/10.35097/1091 https://dx.doi.org/10.35097/1092 https://dx.doi.org/10.35097/1093 https://dx.doi.org/10.35097/1094 https://dx.doi.org/10.35097/1095 https://dx.doi.org/10.35097/1096 https://dx.doi.org/10.35097/1097 https://dx.doi.org/10.35097/1098 https://dx.doi.org/10.35097/1099 https://dx.doi.org/10.35097/1100 Records have been anonymized prior to publishing.
