Material Utilization in Additively Manufactured Layered Systems with a Porous Substrate: A Numerical Case Study of a Thrust Ball Bearing

Metals
In layered systems with porous substrates and a dense solid surface, stiffness and strength are inherently coupled through porosity-dependent relations, influencing their load-bearing behaviour.

The Effects of Blank Geometry on Gear Rolling for Large Gear Modules: Experiments and Finite Element Simulations

IEEE Access, 2018
Gear rolling is a forming process to produce gear wheels by plastic deformation. The advantage of the process is to eliminate the chip formation during production and also to improve the product properties since the non-metallic inclusions will be ...

In Situ Magnetic Ordering and Microfabrication of Liquid Crystal Networks with Discretized Alignment

Advanced Functional Materials, EarlyView.
Miniaturizing liquid crystal network actuators typically demands costly laser writing or digital light processing. A low‐cost photolithography platform couples rotating photomasks with a Halbach magnetic array to discretize in‐plane molecular alignment down to 50 µm, producing programmable, light‐responsive grippers, checkerboards, and origami‐inspired

Changes in Surface Topography and Light Load Hardness in Thrust Bearings as a Reason of Tribo-Electric Loads

Lubricants
The article focuses on the findings of endurance tests on thrust bearings. In addition to the mechanical load (axial load: 10 ≤ C0/P ≤ 19, lubrication gap: 0.33 µm ≤ h0 ≤ 1.23 µm), these bearings are also exposed to electrical loads (voltage: 20 Vpp ≤ U0

Thermoplastic high performance composite gears [PDF]

, 2019
This paper describes the development and testing of gears based on polyetheretherketone (PEEK) and endless carbon fibers. Behind these results is a research project funded by INNOSUISSE with the aim of developing plastic gears with which much higher ...

Biodegradable 3D‐Printable and Coatable Antifouling Composites for Marine Applications

Advanced Functional Materials, EarlyView.
Marine biofouling damages submerged surfaces and raises greenhouse gas emissions. Biodegradable antifouling biocomposites were developed by hot‐mixing beeswax, Tween 80, and calcium stearate or stearic acid. Adjusting the component ratio enables processing via hot‐pressing, 3D‐printing, or dip‐coating.

Influences of the metastability of austenitic stainless steels on the wear behavior in a radial shaft seal system

Journal of Materials Research and Technology
Wear tests were conducted on shafts manufactured from three commercial austenitic stainless steels – AISI 303, 347, 904L – within the context of a sealing contact of radial shaft seal system, where wear resistance is critical to preventing leakage ...
