Rebuilding of Turbocharger Shafts by Hardfacing. [PDF]

Materials (Basel), 2022
This paper presents the results of structural tests and hardness measurements of rebuilding coatings manually applied by the gas tungsten arc welding (GTAW) method on damaged surfaces of steel shafts of turbochargers of automotive engines. Single- and double-layer coatings were applied in an argon atmosphere by fusing a 1.2 mm diameter wire with a ...

A Comparative Assessment of Chromium-Boron Hardfacing Using SMAW and FCAW Techniques. [PDF]

ScientificWorldJournal
This research paper investigates the effectiveness of shielded metal arc welding (SMAW) and flux‐cored arc welding (FCAW) on mild steel substrates for chromium–boron hardfacing. Chromium–boron alloys are hard‐wearing and corrosion‐resistant materials used in industries where wear resistance is critical.

Effect of Combined Grinding–Burnishing Process on Surface Integrity, Tribological, and Corrosion Performance of Laser‐Clad Stellite 21 Alloys

Advanced Engineering Materials, Volume 25, Issue 8, April 2023., 2023
A combined grinding–burnishing surface modification process is applied to the laser‐clad Stellite 21 alloys. Ball burnishing (BB) improves surface topography by lowering surface roughness and porosity. Increased hardness induced by BB is responsible for higher wear and impact resistance. Higher BB force augments surface integrity improvement.

Developing an Empirical Relationship to Predict the Wear Characteristics of Ni‐Based Hardfaced Deposits on Nuclear Grade 316LN Austenitic Stainless Steel

Advances in Materials Science and Engineering, Volume 2021, Issue 1, 2021., 2021
Using the nickel‐based Colmonoy 5 hardfacing alloy, components made of austenitic stainless steel (ASS) used in nuclear power plants can be hardfaced. Hardfacing is the process of applying complex and wear‐resistant materials to substrates that require abrasion resistance.
