Micro-Structures and High-Temperature Friction-Wear Performances of Laser Cladded Cr–Ni Coatings
Cr-Ni coatings with the mass ratios of 17% Cr-83% Ni, 20% Cr-80% Ni and 24% Cr-76% Ni were fabricated on H13 hot work mould steel using a laser cladding (LC). The surface-interface morphologies, chemical elements, surface roughness and phase composition of the obtained Cr-Ni coatings were analysed using a scanning electron microscope (SEM), energy disperse spectroscopy (EDS), atomic force micro...
متن کاملEvaluation of Microstructure and Wear Behavior of Iron-based Hard - facing Coatings on the Mo40 Steel
Mo40 low-alloy steels are mostly used to produce industrial components such as crane wheels which are exposed to abrasive wear. However, during working conditions, their wear resistance is reduced after a while due to its low hardness. With increasing abrasive wear, the dimensions of components decrease and they need to be repaired for surface modification. In this regard, hard overlay coatings...
متن کاملWear and repair of stainless steel crowns.
AIM The purpose of this study was to determine the wear of stainless steel crowns (SSCs) in children, and compare the extent of microleakage in SSCs that had been repaired using either a cermet glass-ionomer cement (GIC) or a packable composite resin (CR). MATERIALS AND METHODS For the first aim, the occlusal surface thickness of 31 harvested SSCs (21 primary first and 10 second molars) and 1...
متن کاملMicrostructure, Wear Resistance and Oxidation Behavior of Ni-Ti-Si Coatings Fabricated on Ti6Al4V by Laser Cladding
The Ni-Ti-Si composite coatings were successfully fabricated on Ti6Al4V by laser cladding. The microstructure were studied by SEM (scanning electron microscopy) and EDS (energy dispersive spectrometer). It has been found that Ti₂Ni and Ti₅Si₃ phases exist in all coatings, and some samples have TiSi₂ phases. Moreover, due to the existence of these phases, coatings presented relatively higher mic...
متن کاملMechanical and electrochemical properties of multiple-layer diode laser cladding of 316L stainless steel
In the present investigation, a detailed mechanical and electrochemical properties of multiple-layer laser clad 316L stainless steel (from the powders produced by gas atomized route) has been carried out. Multiple-layer laser cladding of 316 L stainless steel has been conducted using a diode laser. The mechanical property (microhardness) of the fabricated product has been evaluated using a micr...
