Mar 10, 2021 · Gas nitriding (500°C) and gas nitrocarburizing (540°C to 580°C) are universally accepted procedures, and typically require a high concentration of ammonia (NH 3) and considerable carrier gas flow (normal pressure process) compared with pulse plasma nitriding. The elemental nitrogen gas diffuses into iron and forms hard nitrides. Coatings Free Full-Text Mechanical Investigations of The in-service life of ASTM A36 welded steel pipes in power plants is often shortened by ash corrosion. During the heating condition, the ash deposition on the welded steel pipes gradually reduces the thickness of the pipes, thus, reducing the lifetime. Instead of replacing the pipes with new ones, the cost could be significantly reduced if the lifetime could be further extended. Weld cladding

Effect of methane concentration on surface properties of

Jun 16, 2021 · Plasma nitrocarburizing is a thermochemical diffusion process with simultaneous diffusion of nitrogen and carbon on the surface of metals at elevated temperatures. In this work, the influence of methane (carbon-containing precursor) concentration on the surface properties of the nitrocarburized AISI-304 in the presence of a cathodic cage is studied.

42CrMo steel was adopted as the base material of plasma spray welding, and the 42CrMo chemical composition is shown in Table 1. WC (5390 m, 99.9 wt.%), Co alloy (53165 m) and Fe-based amorphous alloy (1654 m) are all products by Aidun Alloy Material Co., Ltd., Suzhou, China, and their chemical compositions are shown in Table 1. Structure of ium GRADE 1 after Laser Alloying with ium alloys due to their low density and high mechanical properties are a group of materials that are being used willingly nowadays. A promising method of titanium heat treatment is laser surface alloying. Process parameters like laser beam power, its transverse speed, amount of alloying elements and shield gas, have influence on the material.

Study on ized Layer Microstructure of T10 Steel by

The titanized layer was prepared on the surface of T10 steel using a double glow plasma surface alloying (DGPSA) technique. The titanized layer was characterized by SEM and scratch tester. Results showed that the TiC layer with a thickness of 1.5~8.5m was formed on the sample surface at the range of 900°C to 1100°C for the holding time from 2h to 6h, which was homogeneous, dense, and TMS 2020 149th Annual Meeting & Exhibition Supplemental Feb 13, 2020 · TMS 2020 149th Annual Meeting & Exhibition Supplemental Proceedings.

The plasma nitriding treatment of TiN/TiCN multilayer

Abstract The TiN/TiCN multilayer films were deposited by direct current magnetron sputtering, and then the nitriding treatments were carried out in low pressure plasma excited by single-frequency discharge mode. It could be found that the nitriding time had a considerable influence on the composition of uppermost TiCN layer. These variations mainly embodied on the decrement of the Ti C bonds Tiny, agile drones - Aerospace Manufacturing and DesignApr 06, 2021 · Gas nitriding (500°C) and gas nitrocarburizing (540°C to 580°C) are universally accepted procedures, and typically require a high concentration of ammonia (NH 3) and considerable carrier gas flow (normal pressure process) compared with pulse plasma nitriding.
