Universidad de Zaragoza Enhancement of tribological behavior of rolling bearings by applying a multilayer ZrN/ZrCN coating 2019 Access copy available to the general public Unrestricted This paper focuses on the tribological behaviour of ZrN/ZrCN coating on bearing steel substrates DIN 17230, 100Cr6/1.3505. Coatings are applied at room temperature processes by means of Cathodic Arc Evaporation (CAE), a kind of Physical Vapor Deposition (PVD) technique. In order to achieve a satisfactory compromise between coating-substrate adhesion and the surface roughness requirement of the bearing rings, a polish post-processing is proposed. Different polish post-processing times and conditions are applied. The coated and polished bearing rings are tested under real friction torque test protocols. These tests show that the application of the coating does not entail a significant improvement in friction performance of the bearing. However, fatigue tests in real test bench are pending to evaluate the possible improvement in bearing life time. info:eu-repo/grantAgreement/ES/MINECO/RTC-2016-5799-4 info:eu-repo/grantAgreement/ES/DGA-FEDER/T08-17R info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 2.436 2019 MATERIALS SCIENCE, COATINGS & FILMS 10 / 21 = 0.476 2019 Q2 T2 0.463 2019 Materials Chemistry 2019 Q2 Surfaces, Coatings and Films 2019 Q2 Surfaces and Interfaces 2019 Q3 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Lostalé, A.
