Effect of cryogenic-thermal cycling treatment on tribological properties of Ti-based amorphous alloy

Cailiao gongcheng, 2022
The wear resistance of titanium alloy is poor, the preparation of amorphous alloy coating on the surface of titanium alloy moving parts is a choice to maintain the advantages of titanium alloy and improve its wear resistance.

Effects of Multi-Axial Compression on the Mechanical and Fretting Wear Properties of Ti-45Nb Alloys

Metals, 2021
Biocompatible β-type Ti-45Nb alloy with a low elastic modulus is promising in alleviating the stress shielding effect of Ti-based hard-tissue replacement implants. In this work, the ultra-fine-grained (UFG) microstructures with different grain sizes were

Adhesion at friction and wear

Friction, 2022
AbstractOur understanding of the surrounding world, from friction to the origin of life, depends on how we imagine the contact interaction of condensed bodies. What are the forces acting in contact with solids? Do they attract (adhesive) or repel (dehesive)?

ADHESIVE WEAR PREDICTION THROUGH FINITE ELEMENT ANALYSIS IN TRIBOLOGICAL APPLICATIONS [PDF]

Journal of the Egyptian Society of Tribology
 Adhesive wear significantly impacts the performance and longevity of dynamic systems. This study utilizes the finite element method (FEM) to simulate adhesive wear in a pin-on-disc system and calculate the wear volume.

Dry sliding wear of microalloyed Er-containing Al–10Sn–4Si–1Cu alloy

Journal of Materials Research and Technology, 2020
With the rapid development of the machinery industry, bearing materials with better tribological properties are demanded. Al alloys containing Erbium (Er) and Zirconium (Zr) have better comprehensive performance, whose tribological properties have hardly

Adhesive Wear of Fibers

Journal of the Society of Materials Science, Japan, 1966
In our previous paper, 1)2) the mechanism of wear phenomena of fibrous materials was classified into four types under various rubbing conditions. And the relationship between the wear resistance and its mechanical properties was described experimentally as follows;Amount of wear loss ∝total frictional force/modulus×tensile strength×elongationThe ...

Effect of concentration and dispersion of filler fractions on adhesive strength and abrasion resistance of an epoxy and sand composite [PDF]

MATEC Web of Conferences, 2019
The increase in the adhesive strength of the epoxy and sand composite is equally regulated by the content of the sand component and the dispersiveness of its particles.

Adhesive wear mechanism of coated tools and its influence on cutting performance during machining of Zr-based bulk metallic glass

Journal of Materials Research and Technology, 2023
Adhesive wear is the primary failure form of coated tools in zirconium-based bulk metallic glasses (Zr-based BMGs) machining. This work investigated the adhesion formation and failure of TiN/Al2O3/Ti(C,N), Al2O3/Ti(C,N), and TiAlN-coated tools when ...

Establishment of a humanized patient‐derived xenograft mouse model of high‐grade serous ovarian cancer for preclinical evaluation of combination immunotherapy

Molecular Oncology, EarlyView.
We have established a humanized orthotopic patient‐derived xenograft (Hu‐oPDX) mouse model of high‐grade serous ovarian cancer (HGSOC) that recapitulates human tumor–immune interactions. Using combined anti‐PD‐L1/anti‐CD73 immunotherapy, we demonstrate the model's improved biological relevance and enhanced translational value for preclinical ...
