In this study tungsten inert gas (TIG) surface melting of pre- plasma sprayed WC-14%Co low carbon steel has been studied. Surface melting was performed under different heat inputs by using various TIG parameters including intensity and kind of current. Microstructure and microhardness of surface alloyed specimens were then studied. Eutectic structures containing tungsten-rich carbides were shaped in a matrix including martensite lath, when high heat input was used. Decreasing at heat input affected the microstructure of the alloyed layers, and high amount of faceted tungsten-rich carbides (Fe3W3C) were formed in fairly low heat input. Microhardness of melted layers highly improved in comparison with that of the substrate.

“…This alloy is characterized by high corrosion resistance, friction wear resistance, and good properties at elevated temperatures; however, its wear resistance and hardness in demanding applications may not be satisfactory. One way to improve these properties is to add high hardness and wear resistance particles such as tungsten [ 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 ] and titanium [ 19 , 20 , 21 , 22 , 23 ] carbides to the powder and others [ 24 , 25 , 26 ]. As a result of remelting the mixture of these materials, a composite layer can be obtained in which carbides are reinforcing particles distributed in the alloy matrix.…”

Stellite-6/(WC+TiC) Composite Coatings Produced by Laser Alloying on S355 Steel

The paper presents study results of Stellite-6/(WC+TiC) coatings produced by laser alloying with varying contents of reinforcing phases (40%wt and 60%wt content of mixture WC+TiC). The coatings were produced on S355 steel using different laser beam power densities: 76 kW/cm2, 115 kW/cm2 and 153 kW/cm2. The coatings obtained were subjected to microhardness measurements, wear resistance tests, chemical composition analysis and microstructure observations using light microscopy and scanning electron microscopy. It was found that both types of coatings were characterized by higher microhardness and wear resistance in comparison to substrate material. The rate of solidification had an impact on the obtained results of the study.
