Additive Manufacturing Technologies: An Overview about 3D Printing Methods and Future Prospects

Complexity, Volume 2019, Issue 1, 2019., 2019
The use of conventional manufacturing methods is mainly limited by the size of the production run and the geometrical complexity of the component, and as a result we are occasionally forced to use processes and tools that increase the final cost of the element being produced. Additive manufacturing techniques provide major competitive advantages due to

Effect of Tungsten Carbides on Abrasive Wear of Hardfacing Coatings

Advances in Tribology, Volume 2018, Issue 1, 2018., 2018
The aim of this study is to investigate the abrasive wear loss as well as the wear mechanisms of hardfacing layers with and without tungsten carbides (WC) included in the matrix in different friction wheel test (FWT) configurations. The FWT setup is varied in regard to the materials of the rotating wheels, whereat steel and rubber materials are ...

Effects of Different Operating Temperatures on the Tensile Properties of the Grid Plate Hardfaced with Colmonoy in a Pool Type Sodium Fast Reactor

Science and Technology of Nuclear Installations, Volume 2017, Issue 1, 2017., 2017
In sodium‐cooled fast reactors (SFRs), the grid plate is a critical component which is made of 316 L(N) SS. It is supported on a core support structure which is also made of 316 L(N) SS. This assembly is immersed in a pool of sodium which acts as a coolant.

Measurement of the Residual Stresses and Investigation of Their Effects on a Hardfaced Grid Plate due to Thermal Cycling in a Pool Type Sodium‐Cooled Fast Reactor

Science and Technology of Nuclear Installations, Volume 2016, Issue 1, 2016., 2016
In sodium‐cooled fast reactors (SFR), grid plate is a critical component which is made of 316 L(N) SS. It is supported on core support structure. The grid plate supports the core subassemblies and maintains their verticality. Most of the components of SFR are made of 316 L(N)/304 L(N) SS and they are in contact with the liquid‐metal sodium which acts ...

Softening Behavior of a Cold Work Tool Steel and High‐Boron Tool Steel Fabricated by Directed Energy Deposition

steel research international, Volume 95, Issue 3, March 2024.
One cold work tool steel and one high‐boron tool steel are deposited using directed energy deposition for the purpose of hardfacing on dies. The softening behavior at high temperatures and the corresponding mechanisms are investigated in this study. Prolonging the life of hot stamping dies in the automotive industry is challenging. Surface modification

Study the effective factors on the industrial hardfacing for low carbon steel based on Taguchi method

Journal of the Mechanical Behavior of Materials
The most failures that occurred in the contacting surfaces were due to the wear in materials of the mechanical parts (products). The lifetime of any machine element or product will be reduced when the rate of wear increases more than the critical value ...
