Material Build-up Repair for Stainless Steel Equipment | Innovative Repair with Kanmeta Cold Spray

Customer's Challenge:

The customer had been struggling with the lack of existing repair techniques for material loss in stainless steel equipment.

The reasons why conventional methods such as welding or thermal spray could not be applied on this case were as follows:

　1)High heat input from welding causes sensitization, leading to damage of the base material.
　2)Thermal spraying has limitations in coating thickness, making it difficult to provide sufficient environmental barrier capabilities in
　　certain conditions.
　3)Metal putties like Devcon and Belzona do not provide the necessary strength.

Kanmeta Engineering's Proposal:

Kanmeta Cold Spray was chosen for the following reasons:

　1)No high heat input, preventing damage to the base material.
　2)No limitations on coating thickness, with environmental barrier capabilities that can withstand harsh corrosion environments.
　3)Flexible application, making it suitable for repair on existing equipment.

 Results:

　1)Material loss areas were effectively repaired with a thick, high-environmental-barrier cold spray coating, providing a 3D restoration.
　2)The cold spray was applied to stainless steel without causing any adverse effects, despite concerns about heat damage.
　3)The high-performance coating was applied over the existing equipment, eliminating the need for component replacement.
