Fatigue fracture of surface-modified layers in 18CrNiMo7-6 carburized steel

Engineering Failure Analysis, 2022
Abstract A modified layer of a certain thickness is produced on the surface of 18CrNiMo7-6 alloy steel after carburizing and quenching that greatly affects the microstructure and fatigue properties of the material. In this work, the fatigue performance of each layer was studied.

Properties of the surface-modified layer of plasma-oxidized poly(dimethylsiloxane)

MRS Proceedings, 2006
ABSTRACTExposure of poly(dimethylsiloxane) (PDMS) to oxygen plasma creates a thin, stiff surface-modified layer that reaches a submicron depth. Due to a significant modulus mismatch between the stiff surface-modified layer and the compliant bulk PDMS the surface-modified layer forms intricate patterns of surface buckles when under compressive stress ...

Atomic-Layer Electroless Deposition: A Scalable Approach to Surface-Modified Metal Powders

Langmuir, 2014
Palladium has a number of important applications in energy and catalysis in which there is evidence that surface modification leads to enhanced properties. A strategy for preparing such materials is needed that combines the properties of (i) scalability (especially on high-surface-area substrates, e.g.

Inactivation of Listeria monocytogenes on a polyethylene surface modified by layer-by-layer deposition of the antimicrobial N-halamine

Journal of Food Engineering, 2013
Abstract Modification of food contact surfaces to be antimicrobial represents an approach to address the problem of cross-contamination in the food industry. The effect of increasing levels of surface modification on low density polyethylene (LDPE) through application of N-halamines on the inactivation kinetics of Listeria monocytogenes Scott A was

Characterization of elastic-plastic properties of surface-modified layers introduced by carburizing

Mechanics of Materials, 2020
Abstract The mechanical performance of surface-modified layers is important during mechanical-component service. A simpler expression to characterize the carbon content of the surface-modified layers was proposed for alloy steel after carburizing. The tensile test method was used to determine the elastic–plastic properties of the surface-modified ...
