Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

open access: yesAdvanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Influence of Surface Finish on the Tribological Performance of AlTiBN Coatings Deposited on Forming Tools

open access: yesAdvanced Engineering Materials, EarlyView.
Aluminum and nitride coatings are used in industry because they are hard, resist wear, and protect against oxidation. Adding boron can improve friction behavior and other properties. This study tests coatings on surfaces with different finishes. Results show smoother surfaces perform better, while rough ones wear faster, although coatings can reduce ...

STATIC FRICTION COEFFICIENT MODEL OF JOINT SURFACES CONSIDERING ASPERITIES INTERACTION AND SUBSTRATE DEFORMATION (MT)

open access: yesJixie qiangdu, 2023
A statistical model of static friction factor of joint surfaces was deduced, which was more in line with the actual situation and takes into account the interaction of asperities and the deformation of the substrate.

EFFECT OF FILLING MATERIALS ON THE FRICTION COEFFICIENT OF RECYCLED RUBBER FLOORINGS [PDF]

open access: yesJournal of the Egyptian Society of Tribology, 2013
The effect of filling materials on the friction coefficient of recycled rubber floorings is discussed in the present work. Experiments were carried out by the sliding of the bare foot against the tested rubber tiles of different thickness.

Influence of Geometric Design on Mechanical Performance of Auxetic Metastructure

open access: yesAdvanced Engineering Materials, EarlyView.
Strategic geometric reinforcement transforms auxetic performance. This study evaluates 3D‐printed arrowhead metastructures, revealing that a modified design with local ring reinforcement suppresses premature failure to achieve superior energy absorption and structural efficiency.

Precipitation Simulations of the O‐Phase in Ti2AlNb Alloys Processed by Laser Powder Bed Fusion

open access: yesAdvanced Engineering Materials, EarlyView.
Simulated and experimental evolution of the O‐phase volume fraction during postprocessing of a Ti‐21Al‐25Nb (at.%) alloy processed by laser powder bed fusion. With results of sensitivity to input parameters from a thorough and quantified analysis, the interfacial energy matrix/precipitate is the most relevant input parameter for the simulation of the O‐

Moisture Dependent Physical Properties of Chironji (Buchanania Lanzan)Nut [PDF]

open access: yes, 2016
Physical properties of Chironji nut were determined as a function of moisture content, varying from 9.98 to 17.06% (d. b.). Nut length, width, thickness, and geometric mean diameter increased linearly from 9.0 to12.1 mm, 6.9 to10.5 mm, 5.87 to 10 mm and ...
