Load effect in abrasive wear mechanism of cast iron with graphite and cementite
(ELSEVIER SCIENCE SA, 2009)
In this study four irons were casted with different chromium and vanadium contents: 2.66% Cr, 5.01% Cr, 2.51% V and 5.19% V. Their microstructure is composed of: ledeburite, graphite and M(3)C carbides (cementite). ...

It is analyzed through the concepts of tribology and mechanical contact and damage the suggestion of implementing a backup system for traction and passage of Pipeline Inspection Gauge (Pig) from the inside of pipelines. ...
Efeito de partículas de desgaste no comportamento tribológico de metaisEffect of wear debris on tribological behavior of metals
(Universidade Federal de UberlândiaBrasilPrograma de Pós-graduação em Engenharia Mecânica, 2018)
A comparative study on the dry sliding wear behaviour of nitrocarburised, gas nitrided, fluidised-bed nitrided, and plasma nitrided plastic mould steel
(2016-01-01)
Plastic injection moulds suffer wear due to the relative movements of the mould parts and the polymeric material flow which is often reinforced by hard abrasive fibres or whiskers. Several studies were performed on the ...
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 ...
Wear mechanisms and microstructure of pulsed plasma nitrided AISI H13 tool steel
(ELSEVIER SCIENCE SA, 2010)
AISI H13 tool steel discs were pulsed plasma minded during different times at a constant temperature of 400 degrees C Wear tests were performed in order to study the acting wear mechanisms The samples were characterized ...
Orthopaedic implant failure: Aseptic implant loosening - the contribution and future challenges of mouse models in translational research
(Portland Press Ltd, 2015)
Aseptic loosening induced by UHMWPE wear particles is considered the main cause of longterm implant failure in orthopaedic surgery. The current therapy consists of surgical revision
and implant replacement, carrying severe ...

(Elsevier Science Sa, 2016-12-29)
Wear damage and resulting triboparticles corresponding to fretting of Incoloy 800 steam generator tubes against AISI 304 pads were characterized in experiments performed in air at room temperature in a 90° cross cylinder ...
Wear and Corrosion Interactions on Titanium in Oral Environment: Literature Review
(2015)
The oral cavity is a complex environment where corrosive substances from dietary, human saliva, and oral biofilms may accumulate in retentive areas of dental implant systems and prostheses promoting corrosion at their ...
Friction and wear properties of functionally graded aluminum matrix composites
(2003-06-25)
Aluminum matrix composites are currently considered as promising materials for tribological applications in the automotive, aircraft and aerospace industries due to their great advantage of a high strength-to-weight ratio. ...
