Repair and Dimensional Restoration

Machine parts and other metal surfaces can become worn over time due to exposure to heat, chemicals, abrasion, or mechanical contact. This wear can cause the parts to function less efficiently or fail. When components fail, you can either replace them or resurface them, often at for significantly less cost than replacement. Thermal Spray offers an effective way to repair and restore worn surfaces and even to improve part performance and service life.

Benefits of Repair and Dimensional Restoration

• Provides a cost-effective alternative to replacement
• Repaired parts can often outperform new parts
• Repair is often less disruptive than replacement
• Dimensional restoration can be used to repair worn or damaged surfaces without machining

Common Applications of Repair and Dimensional Restoration

Thermal spray repair and dimensional restoration is applied throughout all major industries for various applications.

The Process for Repair and Dimensional Resurfacing

The thermal spray repair and dimensional restoration process begins with removing the damaged or worn surface. The surface is then cleaned and prepared for the thermal spray coating application. The coating is applied to the surface using plasma, HVOF, arc wire, or flame spraying. Once the coating has cooled, it is machined, ground, or hand polished to the desired shape and finish.

Advantages of Thermal Spray Repair and Dimensional Restoration

Thermal spray repair and dimensional restoration offer many advantages over traditional methods of repair and resurfacing. These advantages include:

• A wide range of coatings can be applied with thermal spray, including metals, ceramics, plastics and composites. This allows you to tailor the repair or resurfacing to the specific needs of your application.
• Thermal spray coatings can be applied quickly and easily, with minimal downtime for your operation. Repairs can often be accomplished in hours or days.
• Thermal spray coatings often provide a higher level of wear resistance than the original surface, extending the life of the component.
• Thermal spray can be used to repair or resurface irregularly shaped surfaces.
• In many cases, thermal spray coatings can be applied without the need for elaborate fixturing, saving time and money.
