Despite this, DLC has poor adhesion properties, which makes it challenging to use in industrial applications. The application of DLC using the high-power pulse magnetron sputtering (HiPIMS) technique with positive pulses has been studied. Seeking greater DLC coating adherence, the application of a nitriding pretreatment prior to the DLC coating has been studied to improve its adhesion to AISI316L stainless steel soft metal substrates, employing active screen plasma nitriding (ASPN). The influence of the different pretreatment temperatures to reach the maximum levels of adhesion has been analyzed. Scratch methods have been employed to assess adhesion. The elemental composition, morphology, and roughness of the samples have been studied, as well as the behavior of resistance to wear and friction. The results show an improvement in DCL adhesion. Critical loads (LC3) increase at higher pretreatment temperatures, from 48 N for the DLC to 82 N for the ASPN + DLC. Pretreatment has also been shown to be effective in maintaining excellent dry wear resistance properties and a low coefficient of friction.112638567enginfo:eu-repo/semantics/openAccessjournal article10.1155/2022/5621154Diamond-like carbon (DLC) coatingsAdhesion propertiesDiamond-like carbon (DLC) coatingsAdhesion propertiesGeneral Materials ScienceGeneral EngineeringFunding InfoThis research was supported by the Government of Navarra grants for hiring doctoral students (Iñigo G´omez) by companies and research and knowledge dissemination organizations: industrial doctorates 2019–2021, grant no. 0011-1408-2018-000000 and CDTI Ministerio de Ciencia e Innovaci´on of Spain through the project CERVERA (CER2019-1003).This research was supported by the Government of Navarra grants for hiring doctoral students (Iñigo G´omez) by companies and research and knowledge dissemination organizations: industrial doctorates 2019–2021, grant no. 0011-1408-2018-000000 and CDTI Ministerio de Ciencia e Innovaci´on of Spain through the project CERVERA (CER2019-1003).http://www.scopus.com/inward/record.url?scp=85143433296&partnerID=8YFLogxK
