Behaviour of nickel coatings made by brush plating technology in conditions of cavitation erosion and corrosion
(Peer reviewed; Journal article, 2023)The basic hypothesis of the research was that the structure of the coating, i.e. the type of defects, affects the mechanical and electrochemical properties, as well as the resistance to cavitation erosion and corrosion. ... -
Complex eigenvalue analysis and parameters analysis to investigate the formation of railhead corrugation in sharp curves
(Peer reviewed; Journal article, 2020)Rail corrugation, a quasi-sinusoidal irregularity of the rail head, is a common issue experienced throughout the railway networks worldwide. It generally leads to high wheel-rail dynamic loads, increased noise emission, ... -
Concrete-ice abrasion: wear, coefficient of friction and ice consumption
(Journal article; Peer reviewed, 2018)Concrete structures in the Arctic offshore are often exposed to drifting ice causing abrasion of concrete surfaces. This paper presents the results of a laboratory study of concrete-ice abrasion. The sawn concrete surfaces ... -
Contact point lateral speed effects on contact strip wear in pantograph – catenary interaction for railway operations under 15 kV 16.67 Hz AC systems
(Peer reviewed; Journal article, 2021)The design of a railway catenary is subject to multiple decisions regarding the geometry of the system. In particular, the horizontal geometry of the contact wire determines the evolution of the wear of the contact wire ... -
FE8 type laboratory testing of white etching crack (WEC) bearing failure mode in 100Cr6
(Journal article; Peer reviewed, 2019)WEC is an aggressive and unpredictable failure mode affecting bearings in particular in the wind energy sector. This paper focuses on the most common used method for WEC laboratory accelerated testing, the FE8 type test ... -
A heuristic wear model for the contact strip and contact wire in pantograph – Catenary interaction for railway operations under 15 kV 16.67 Hz AC systems
(Peer reviewed; Journal article, 2020)The sliding contact between the pantograph and catenary allows the correct operation of electric trains. However, this contact induces wear on both the components involved in the process, namely the contact strip on the ... -
Reciprocating sliding wear behavior of high-strength nanocrystalline Al84Ni7Gd6Co3 alloys
(Journal article; Peer reviewed, 2017)Nanocrystalline Al-Ni-Gd-Co alloys with exceptionally high hardness have been recently developed from amorphous precursors. In the present work, the reciprocating sliding wear in the gross slip regime of these novel ... -
Topography studies of concrete abraded with ice
(Journal article; Peer reviewed, 2019)Topography studies of concrete-ice abrasion were made to proceed in our understanding of the mechanisms of concrete wear by ice on Arctic offshore structures. The effects on various initial surfaces of a B75 normal-weight ... -
Using acoustic emission signal categorization for reconstruction of wear development timeline in tribosystems: Case studies and application examples
(Journal article; Peer reviewed, 2018)The purpose of this work is to demonstrate how a new acoustic emission (AE) technique can be used to monitor friction surface degradation in a four-ball tribosystem under different types of lubrication. The AE method is ...
