Research on rail steel repair with Stellite 6 powder using a laser metal deposition process was investigated and reported in this study. Rail failures due to excessive wear other head defects can increase the risk of operation reliability problems service life. This study examines deposited material compatibility cobalt-based alloy, head-hardened R350HT grade substrate. Materials characterizati...

Laser cladding is widely used for feature repair and manufacturing of large structural components. However, due to processing parameters thus energy densities variation, defects can form in laser clad materials. There a need understand the relationship between quality. This study therefore investigates critical producing Stellite® 21 (Co-Cr-MoNiC) alloy by cladding. Compared with conventional m...

The paper presents study results of Stellite-6/(WC+TiC) coatings produced by laser alloying with varying contents reinforcing phases (40%wt and 60%wt content mixture WC+TiC). were on S355 steel using different beam power densities: 76 kW/cm2, 115 kW/cm2 153 kW/cm2. obtained subjected to microhardness measurements, wear resistance tests, chemical composition analysis microstructure observations ...

Stellite alloys have good wear resistance and maintain their strength up to ~ 600°C, making them suitable for various industrial applications like cutting tools combustion engine parts. This investigation was aimed at i) manufacturing new alloy blends using powder metallurgy ii) mathematically mapping hardness, yield strength, ductility impact energy of base blends. Linear, exponential, polynom...
