Cobalt 6 Powder for Cladding

The Cobalt 6 Powder is recognized for its superior hardness, resistance to wear and tear, and excellent bond strength. It offers a unique balance between hardness and toughness, ensuring optimal performance under demanding conditions.

Cobalt 6 Powder is extensively used in laser cladding and plasma cladding. These cladding techniques extend the life of machine parts, improving their resistance to wear and corrosion.

Plasma spraying is a thermal coating process where the material is heated to a very high temperature in a plasma torch, creating a molten or semi-molten state. The heated particles are then accelerated and propelled toward the workpiece to form the coating. The plasma spraying process typically requires larger particle sizes because the high temperature of the plasma torch can efficiently melt these particles, and Larger particles also help to create thicker coatings.

On the other hand, laser cladding uses a laser as the heat source to create a melt pool on the surface of the workpiece, and then introduces the powder into this melt pool. The powder melts and mixes with the substrate material to form a coating. Laser cladding generally requires smaller particle sizes for a few reasons. Firstly, smaller particles can be more easily and accurately delivered into the laser-created melt pool. Secondly, smaller particles melt more quickly and fully in the melt pool, leading to a more homogeneous and fine-grained microstructure in the final coating. Lastly, smaller particles can result in smoother coatings with less porosity.

SYTOP has powders with different particle sizes for different cladding processes.
