Microstructural characterization and microscopy analysis of laser cladding Stellite12 and tungsten carbide

Microstructure and properties of thin wall by laser cladding forming

“…The generation of W 2 C may result from the decomposing of WC during laser cladding. The formation of M 23 C 6 is similar to that observed in the previous investigations of the laser cladding of the WC Co Cr C composite coatings on SK3-carbon tool steel by Chiang and Chen (2007) and the WC/Ni60B coatings by Chen et al (2008) and the laser rapid cladding of Ni-based WC composite coatings by Zhou et al (2008).…”

Sliding wear characteristics of molybdenum containing Stellite 12 coating at elevated temperatures

“…Being motivated by the necessity for further enhancement in wear resistance, several attempts have been made to modify Stellite hardfacing alloys by adding alloying elements or reinforcing with hard ceramic particles [4,7,[10][11][12][13][14]. Promising enhancements in room temperature (RT) wear resistance have been reported upon introduction of molybdenum into Stellite 6 and low carbon Stellite alloys as the result of its solid solution hardening effect and carbide forming tendency [4,11,14].…”

Laser cladding of SiC/Si composite coating on Si–SiC ceramic substrates

“…Powder fed laser cladding is a process to produce protective layers against wear and/or corrosion on highly loaded components [6,7]. The precise and localized heat regime produced during laser cladding overcomes the drawbacks of the welding techniques [8].…”
