High index top layer for multimaterial coatings [PDF]

open access: yes, 2016
For application in future cryogenically cooled gravitational wave detectors, the thermal noise of low absorbing mirror coatings has to be reduced. The development of low mechanical and optical loss materials is challenging, but thermal noise reduction ...

Physical and Tribological Properties of Nitrided AISI 316 Stainless Steel Balls

open access: yesMATEC Web of Conferences, 2016
AISI 316 austenitic stainless steel balls (diameters 5.0 and 12.0 mm, typical hardness 250 HV0.3) and flat samples (20×20×2.0 mm) were nitrided by a pulsed glow discharge Ar/N2 plasma. Hardness of the ball surfaces was analysed using Vickers indentation.

Room temperature-curable, easily degradable, and highly malleable and recyclable vanillin-based vitrimers with catalyst-free bond exchange

open access: yesPolymer Testing, 2022
Development of bio-based vitrimers attracted significant attention due to these species’ excellent recyclability and renewability. However, most bio-based vitrimers require high-temperature curation and catalyst use.

Optical and Physical Properties of Methyltrimethoxysilane Transparent Film Incorporated with Nanoparticles

open access: yesAdvances in Materials Science and Engineering, 2012
Methyltrimethoxysilane has been used as a base in the formation of transparent sol-gel coatings on glass substrates. Several types of alcohol were used as solvents in order to obtain the highest transparency and scratch hardness of the film.

Sliding wear of a-C:H coatings against alumina in corrosive media [PDF]

open access: yes, 2013
This paper reports the results obtained from the study of friction and sliding wear in two corrosive solutions of an a-C:H coating deposited on 316L stainless against an alumina ball, employed as static counter part. Calculations of the values of the von

Friction of Teflon-S-coated Ti-6Al-4V under conditions of oscillatory relative motion [PDF]

open access: yes, 1990
An extendable prosthesis for implantation in a human leg has been developed. The friction forces during extension of the prosthesis must be low, so a coating of Teflon-S was applied to the sliding surfaces. During walking, damage can occur as a result of

Effect of solid oxidation products on the ablation mechanisms of ZrC and HfC based coatings above 2000°C

open access: yesJournal of Materials Research and Technology, 2023
Solid and liquid oxidation products have been considered to be the key issues to influence the ablation resistance of UHTCs coatings. However, the effect of solid oxidation products on the ablation performance is not clear.
