Dataset supporting the study: 'Wear resistance of an additively manufactured high-carbon martensitic stainless steel', E. Iakovakis et al., 2022 The dataset contains the hardness, the friction values, the x,y,z coordinates from profilometry measurements for the wear rate calculation and the generation of the surface profile map of the track and the hardness data to generate the cross-sectional hardness map of the wear tracks of an additive manufactured (EBM-processed) high-carbon martensitic stainless steel (Vibenite®350). Most specifically, it incudes the following: Hardness measurement file (Hardness vibenite350 HV5.csv): The .csv file reports the hardness for 30 measurements. Reciprocating tests files (Vibenite 350 cof1/2/3 alumina 3N/10N.csv): The .csv files report the testing parameters and the friction forces of the reciprocating dry wear tests. Profilometry measurements files (Vibenite 350 profilometry1/2/3 3N/10N.dat and Vibenite 350 profilometry data map_5umscan at 3N/10N): The .dat files report the x,y,z coordinates of the wear track used for the calculation of the wear rate for Vibenite®350 and for the generation of the surface profile maps. Hardness data in the cross-section of the wear track files (Vibenite 350 hardness data map at 3N/10N.spe): The .spe files report the hardness values measured in the cross-section of the wear track and used to generate the hardness maps. The dataset also includes tribological data for an additive manufactured (EBM-processed) high carbon martensitic tool steel (Vibenite®150) which is used as a reference material to compare the wear rate data of the EBM-processed martensitic stainless steel. Most specifically, it incudes the following: Reciprocating tests files (Vibenite 150 cof1/2/3 alumina 3N/10N.csv): The .csv files report the testing parameters and the friction forces of the reciprocating dry wear tests. Profilometry measurements files (Vibenite 150 profilometry1/2/3 3N/10N.dat ): The .dat files report the x,y,z coordinates of the wear track used for the calculation of the wear rate for Vibenite®150 and for the generation of the surface profile maps..
