Stellite Coating

This coating is used to produce magnetic, wear- and corrosion-resistant, and high-strength products, where temperature stability is important. Surface coating encompasses many different deposition techniques where the use of alloys based on cobalt powders is common, such as HVOF (High-Velocity Air Fuel), laser cladding, and plasma transferred arc (PTA).

 techniques like high velocity oxy-fuel (HVOF) are also widely used to deposit such materials.

The present study investigates wear and  of Stellite 6 deposited by cold spray in comparison to PTA-deposited Stellite 6, aiming to obtain a very dense coating without the dilution zone typically resulting from PTA weld surfaces.
