Laser Cladding for Valve Manufacturing
LCV NV
Thermo Spray (ex. HVOF)
• Mechanical bond
• Porosity and micro structure defects
Hard Facing
• Metallurgical bond
• Dissolved carbide structure, high-
themp gradient
WHAT IS LASER CLADDING
Metal
Powder
Ceramic
Powder
Powder and transport gas
Laser
Melt pool
Shield gas
Laser cladding is a weld overlay technique where
metallic powder is metallurgically joined to
substrate by means of laser generated energy
Metallurgical bond  increased durability
Minimal heat input  limited deformation
•Fine microstructure -> extra hardness
3
FEATURES
STELLITE HARDFACING with increased hardness (50HRC)
INCONEL WELDOVERLAYS with minimal dillution (0,1MM)
CARBIDE COATINGS with increased wear resistance (4X better compared to HVOF)
Value Proposition
BENEFITS
IMPROVED QUALITY - extra hardness & wear resistance, minimal heat input & dillution
COST REDUCTION – thin layer material saving, fast & automated application process
SCALABLE – consistent high quality for 1 to 100,000 parts
VALVE
APPLICATIONS
