Experimental and numerical analysis of dry contact in the pin on disc test
(Amsterdam, 2013)
The reduction of friction and wear in systems presenting metal-to-metal contacts, as in several mechanical components, represents a traditional challenge in tribology. In this context, this work presents a computational ...
Determination of wear in internal combustion engine valves using the finite element method and experimental tests
(Elsevier, 2016-10)
A methodology for the analysis of wear in internal combustion engine valves is proposed, which is the result of the combined use of numerical and experimental techniques. The numerical solutions are obtained using a ...
Tribological Behavior Analysis of the ISO 5832-1 Austenitic Stainless-Steel Treated by Optical Fiber Laser Used for Biomedical Applications
(2019-11-15)
The present work analyzed the influence of an optical fiber laser surface treatment process on the tribological behavior of the ISO 5832-1 austenitic stainless-steel, basing on the wear volume and friction coefficient. ...
Efeito da adição de boro na microestrutura e na resistência ao desgaste do aço inoxidável AISI 430 conformado por spray
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEM, 2014-08-04)
The contact between drill pipes during oil well exploitations induces a severe wear process that might cause well bore pipe wall rupture, fluids leakage, environmental impacts, and possibly fatal accidents. The problem is ...
Mechanical, and tribological properties of ti/tin bilayers: the dependence of ti interlayer thickness
(Universidad Nacional de Colombia Sede Medellín, 2013)
Ti/TiN bilayers were grown on AISI 316L stainless steel and Dynasil (SiO2) substrates, by using a reactive DC magnetronsputtering system. The Ti interlayer was grown at different thicknesses (0, 50, 100, and 200 nm) in ...

(Universidad Nacional de ColombiaBogotá - Ingeniería - Maestría en Ingeniería - Materiales y ProcesosFacultad de IngenieríaBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá, 2023-01-16)
Las piezas de ingeniería usadas en la industria automotriz como ejes, cardanes, bielas, cigüeñales, engranajes y calipers, entre otros, son fabricados en material ADI, estas piezas están sometidas principalmente a condiciones ...
Resistencia a la corrosión y al desgaste de recubrimientos nanoestructurados de Zirconia (ZrO2) – Plata (Ag) y/o Alúmina (Al2O3) obtenidos con técnica de “Sputtering” reactivo con magnetrón desbalanceado
(Bogotá - Ingeniería - Doctorado en Ingeniería - Ciencia y Tecnología de MaterialesUniversidad Nacional de Colombia - Sede Bogotá, 2019-06-24)
In this work, the effect of doping materials (alumina and / or silver) on the corrosion and wear resistance properties of zirconia nanostructured coatings stabilized with yttria was evaluated. Substrates of 316L steel, ...
