Corrosion and tribocorrosion behaviour of Al-Si-Cu-Mg alloy and its composites reinforced with B4C particles in 0.05M NaCl solution
(2013-08-30)
The corrosion behaviour of metal matrix composites (MMCs) is strictly linked with the presence of heterogeneities such as reinforcement phase, microcrevices, porosity, secondary phase precipitates, and interaction products. ...
Combined Influence of Fluoride and Biofilms on the Biotribocorrosion Behavior of Titanium Used for Dental Applications
(2015-09-01)
Dental implant failures occur mainly due to biofilm infections and mastication micro-movements or load stresses that may induce wear degradation. Dental implants’ microgaps are highly susceptible areas for biofilm formation ...
Ultra-low friction coefficient in alumina-silicon nitride pair lubricated with water
(ELSEVIER SCIENCE SALAUSANNE, 2012)
In a ball-on-disc wear test, an alumina ceramic body sliding against a silicon nitride ceramic body in water achieved an ultra-low friction coefficient (ULFC) of 0.004. The profilometer and EDX measurements indicated that ...
Transições no regime de desgaste por deslizamento do aço inoxidável austenítico AISI 316L processado a plasma
(Universidade Federal de Minas GeraisUFMG, 2014-02-27)
This work investigate the influence of different plasma treatments on the wear resistance of AISI 316L austenitic stainless steel. The chosen plasma treatments were: nitriding conducted at 450°C for 5 hour, carburizing at ...
Synergism between corrosion and wear on CoCrMo−Al2O3 biocomposites in a physiological solution
(2015-11-01)
The use of metal matrix composite structures in biomedical implants can be a solution for decreasing the amount of degradation products. Thus, the present work aims to investigate the synergism between corrosion and wear ...
Canine guidance reconstruction with ceramic or composite resin: A 3D finite element analysis and in vitro wear study
(2022-01-01)
Statement of problem: Wear of the maxillary canine cusps is a common clinical condition which can affect function and esthetics and, in some situations, lead to occlusal pathology. The mechanical behavior of different ...
Mecanismos de desgaste de poliuretano em ensaios de microabrasão
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Engenharia MecânicaTecnologia de Materiais; Projetos Mecânicos; Termociências, 2006-02-13)
Wear mechanisms and thermal history of two non-conforming sliding surfaces was investigated in laboratory. A micro-abrasion testing setup was used but the traditional rotative sphere method was substituted by a cylindrical ...
