An Investigation into the Wear Behavior of Martensitically Transformed Nitrided Layers

Lubricants, 2023
To improve the service behavior of gears, surface heat treatments such as nitriding or induction hardening can be performed. Since these processes are limited in their achievable maximum hardness or depth of hardness, a combination treatment could allow ...

Titanium-modified plasma nitriding layer and enhanced properties for 42CrMo steel

Journal of Materials Research and Technology, 2022
In order to obtain a nitriding layer with thicker ductile diffusion layer and thinner brittle compound layer, plasma nitriding with titanium addition was carried out at 540 °C for 4 h for 42CrMo steel, the characteristic of titanium modified nitriding ...

Surface Treatment of Tool Steel in Controlled Plasma Nitriding Environment

Tribology Online, 2008
Nitriding of tool steel was investigated in a controlled electron beam excited nitrogen plasma environment. The samples were nitrided in two distinct regions, a region with high plasma density and a region with low plasma density called the irradiated ...

EFFECT OF TIME ON THE COMPOUND LAYER FORMED DURING SALT BATH NITRIDING OF AISI 4140 STEEL

Acta Metallurgica Slovaca, 2018
This research was carried out to study the effect of time on the compound layer of AISI 4140 steel in salt bath nitriding. The nitriding process were implemented on AISI 4140 steel in salt bath component for different times (from 1 h to 10 h) at 580 °C ...

Carburizing of Ti–6Al–4V alloy: Structure, growth mechanism and wear performance

Journal of Materials Research and Technology, 2023
Ti–6Al–4V alloy was pack carburized at temperatures of 950–1100 °C within a holding time range of 1–10 h. The structures and constituent phases of carburized layers were analyzed by optical microscope, scanning electron microscope (SEM) and X-ray ...

Plastron induced drag reduction and increased slip on a superhydrophobic sphere [PDF]

, 2011
On low contact angle hysteresis superhydrophobic surfaces, droplets of water roll easily. It is intuitively appealing, but less obvious, that when such material is immersed in water, the liquid will flow more easily across its surface.
