Thermal analysis of microstructural evolution of Al2O3 surface modified layers [PDF]

Surface and Coatings Technology, 2010
Solidification behavior and microstructural evolution of surface modified layers in plasma cladding technique are studied via numerical simulations. Both the coupling effect of temperature and solid volume fraction are considered in the proposed thermal analytical model, by which the transient temperature distributions are calculated and the shape of ...

Mechanism and patterns of wear of chrome steels with a surface-modified layer

Materials Letters, 2021
Abstract The paper presents the results of contact wear studies of surface layers of 6Cr4Mo2VSi steel under the action of pulsating contact stresses. Differences in wear resistance of surface layers of materials are shown, in interrelation with modes of synthesis of their structure and properties.

The Formation of a Modified Surface Layer on Elastomeric Materials [PDF]

Tribology Letters, 2019
Surface modification of an elastomer may be formed during sliding contact with a rigid counter surface. This alteration leads to a change of mechanical properties at the surface and as a result a change in frictional behavior.

Ultrasonic characterization of surface modified layers

Metallurgical Transactions A, 1987
Nondestructive techniques are required for the in-process characterization of rapidly solidified and surface modified layers to fulfill the role of sensors in emerging intelligent materials processing technologies. In steels, where surface modificationvia directed high energy sources is being investigated for surface hardening, it has been found that a

Preconcentration and Determination of a Phospholipid at a Surface Modified by Layer‐by‐Layer Assembly

Electroanalysis, 2007
AbstractElectrochemical oxidation of a phospholipid, phosphatidylcholine (PC), was accomplished at a 4‐aminothiophenol (ATP)‐modified gold electrode coated with a layer‐by‐layer assembly of an electrochemical catalyst (dirhodium phosphomolybdic acid), a trapping agent for PC (a cyclophane, CP, derivative, 1,4‐xylylene‐1,4‐phenylene‐diacetate), and a ...

Existence of a Tribo-Modified Surface Layer on SBR Elastomers: Balance Between Formation and Wear of the Modified Layer [PDF]

Tribology Letters, 2015
In most of the tribological contacts, the composition and tribological properties of the original interface will change during use. The tribo-films, with modified properties compared to the bulk, are dynamic structures that play a significant role in ...

Layer-by-layer assembly surface modified microbial biomass for enhancing biorecovery of secondary gold

Waste Management, 2017
Enhancement of the biosorption capacity for gold is highly desirable for the biorecovery of secondary gold resources. In this study, polyethylenimine (PEI) was grafted on Shewanella haliotis surface through layer-by-layer assembly approach so as to improve the biosorption capacity of Au(III). Results showed that the relative contribution of amino group

Modeling of Surface Modified Layers in the Presence of Surface Irregularities

Journal of Tribology, 1996
Finite element calculations that examine the effects of surface modification on the deformation produced by pure rolling contact are presented. The model simulates the repeated, two-dimensional (line) contact of a cylinder that is rolling over a semi-infinite half space.

Antiglare and antireflective coating of layer-by-layer SiO2 and TiZrO2 on surface-modified glass

Applied Surface Science, 2019
Abstract Antiglare and antireflection materials take considerable research attention due to its important role in transparent optical materials for various purposes. In this study, we employed layer-by-layer coating materials consist of SiO2 and TiZrO2 deposited on etched-surface glass substrate using dual electron beam evaporator system. The surface

New preparation method for surface-modified inorganic layered compounds

Journal of Materials Chemistry, 1996
New surface-modified inorganic layered compounds have been prepared by the reaction of Zn(OH)2 with organic oxychlorides in which 71–98% of the OH groups reacted. Their layered structures are similar to those of the layered double hydroxides (LDHs). Although LDHs have cationic charges, the reaction products are uncharged. The interlayer spacings of the
