Development of a post oxidizing process over nitrided and nitrocarburized steels for wear and corrosion protection
Brühl, Sonia Patricia; Dalibón Bähler, Eugenia Laura; Cabo, Amado; Carfi, Guillermo Rodolfo; Crimello, Pablo (2018-09-20)The environmental concern on the use of this coating stimulated the research activities for alternatives of hard chromium. In this work, AISI 1045 was nitrocarburized, AISI 4140 was nitrided, both in a DC Plasma industrial ... -
Development of a post oxidizing process over nitrided medium alloy steels for wear and corrosion protection in oil sucker rod lift
Cirimello, Pablo; Brühl, Sonia Patricia; Dalibón Bähler, Eugenia Laura; Cabo, Amado; Carfi, Guillermo Rodolfo; Aguirre, Luis Alberto (2018-09-28)To study this surface treatment, AISI 4140 polished PPD prototypes were nitrided, in a DC Plasma industrial equipment, and then were oxidized in the same chamber. Witness specimens were also treated and analyzed in the laboratory. -
Extensión de durabilidad de pistones de bombas de fractura hidraúlica mediante el empleo de tecnología de nitruración por plasma y PVD
Cirimello, Pablo; Brühl, Sonia Patricia; Aguirre, Luis Alberto; Morris, Walter; Carfi, Guillermo Rodolfo (Asociación Argentina de Tribología, 2017-10)En la industria del Gas y el Petróleo (Oil&Gas), el concepto de fractura hidráulica consiste en “romper” la formación (reservorios) por intermedio de un fluido, básicamente formado por agua y arena (agente de sostén), que ... -
