However, in friction tests performed at different temperatures, the effect of the deep sub-zero treatment is uncertain. This study, it was aimed to increase the wear resistance of CPPU steel at different temperatures (room temperature and 150 degrees C) with deep subzero process treatment (-150 degrees C). Friction wear tests were carried out on a pin-on-disc vertical tester according to ASTM standard G99-05. Field emission scanning electron microscopy and atomic force microscopy were used for worn surface analyses. In tests performed at 150 degrees C, the friction coefficient was reduced by 110.33% and the wear resistance was increased by 101.66% with the sub-zero treatment compared to the conventional heat treatment. The deep sub-zero treatment reduced the adhesive wear.en10.1177/09544089221122083info:eu-repo/semantics/closedAccessCppu Steel; Deep Sub-Zero Treatment; Sliding Friction; Atomic Force Microscopy; Worn SurfaceD2 Tool Steel; Cryogenic Treatment; Tribological Behavior; Taguchi Optimization; Surface-Roughness; Resistance; Microstructure; HardnessArticle2-s2.0-85137043687WOS:000845052800001Q3Q3
