A comparative study of corrosive-erosive effects at AISI D3 steel, 304 stainless steel and CrN/AlN material
Caicedo Angulo, Julio Cesar; Cabrera Cifuentes, Gerardo; Caicedo, H. H.; Aperador, William (The Open Materials Science Journal, 2012-02)Corrosive-erosive effect on AISI D3 steel, 304 stainless steel and CrN/AlN coating in aqueous NaCl slurries was studied. CrN/AlN multilayer films with a thickness of 3 µm and bilayer period of Λ = 60 nm (50 bilayers) were ... -
Corrosion-erosion effect on TiN/TiAlN multilayers
Cabrera Cifuentes, Gerardo; Caicedo Angulo, Julio César; Aperador, William; Amaya, César; Escobar, C. (Springer, 2011-12-16)The goal of this work is to study electrochemical behavior under corrosion-erosion conditions for [TiN/ TiAlN]n multilayer coatings with bilayer number (n) of 2, 6, 12, and 24 and/or bilayer period (K) of 1500, 500, 250, ... -
Determination of the best behavior among AISI D3 steel, 304 stainless steel and CrN/AlN coatings under erosive-corrosive effect
Caicedo Angulo, Julio Cesar; Cabrera Cifuentes, Gerardo; Aperador, William; Caicedo, H.H.; Mejía, Aura S. (Elsevier, 2012-07)The erosive-corrosive effect of aqueous NaCl slurries on metals and metals coated with a multilayer system was analyzed. The erosion-corrosion experiments were performed in a test machine in which the impingement velocity, ... -
Nature in corrosion–erosion surface for [TiN/TiAlN]n nanometric multilayers growth on AISI 1045 steel
Caicedo Angulo, Julio Cesar; Cabrera, Gerardo; Caicedo, H.H.; Amaya, César; Aperador, William (Elsevier, 2012-04)The aim of this work is to characterize the electrochemical behavior of [TiN/TiAlN]n multilayer coatings under corrosion–erosion condition. The multilayers with bilayer numbers (n) of 2, 6, 12, and 24 and/or bilayer period ... -
