Fatigue Limit of Custom 465 with Surface Strengthening Treatment. [PDF]

open access: yesMaterials (Basel), 2020
In order to study the effect of nitriding or shot peening on the surface modification and fatigue properties of martensitic stainless-steel Custom 465, the residual stress and micro-hardness of the strengthened layer are determined by X-ray and micro-hardness tester, respectively. The up-and-down method is used to measure the rotational bending fatigue

STRENGTHENING OF ANCHOR CHANNELS ON THE CONCRETE SURFACE

open access: yesce/papers, 2023
AbstractFor the installation of curtain wall systems, the positions of anchor channels gradually move closer to the edge of the concrete slabs. But close to the edge of the slab, conventional supplementary reinforcements have problems to redistribute the loads to the reinforcement due to the short bond length that is available after concrete edge ...

Research progress in wear resistance of high entropy alloy coatings prepared by laser cladding

open access: yesCailiao gongcheng, 2022
The friction and wear of mechanical parts mainly occurs on the surface of the material, and about 80% of the failures of parts are caused by surface wear.Friction and wear increase the loss of material and energy, and reduce the reliability and safety ...

Surface Strengthening of High-Alloyed Martensitic Steel by Staged Nitriding [PDF]

open access: yesMATEC Web of Conferences, 2021
Gas nitriding processes with cyclical rotation of ammonia and ammonia/air atmospheres are suggested for surface strengthening of martensitic Cr-Ni-W-Mo-V steel. One-, two-, and three-staged processes were studied differing by gas atmospheres at the final
