The document discusses laser cladding technology for valve manufacturing, emphasizing the benefits of hardfacing with materials like stellite and inconel, which offer increased hardness, wear resistance, and reduced deformation. It highlights the cost efficiency of thin layers and the scalability of the process for producing high-quality valve components ranging from 1 to 100,000 parts. The document also lists various materials' properties, specifications, and contact information for further inquiries.

1. Laser Cladding for Valve Manufacturing
LCV NV

2. Thermo Spray (ex. HVOF)
• Mechanical bond
• Porosity and micro structure defects
Hard Facing
• Metallurgical bond
• Dissolved carbide structure, high-
themp gradient

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
