Repair techniques to extend the life of your parts

The repair of worn, deformed or out-of-tolerance parts is a major challenge in many industrial sectors, where the durability and precision of components are essential. There are several techniques widely applied in the fields of aeronautics, automotive, energy and industrial manufacturing to restore expensive and complex parts while optimizing equipment performance and reliability.

Our strengths:

APS Group companies offer some of the most effective techniques for restoring parts such as hard chrome plating, thermal spray metallization and grinding:

• Hard chrome plating makes it possible to produce extra thicknesses which will then be ground to size. These coatings provide excellent resistance to wear and corrosion, thus extending the life of critical parts.
• HVOF or HP_HVOF spray allows layers of tungsten carbide to be deposited on parts exposed to oxidation or on joint or braid surfaces.
• Plasma spray offers the possibility of depositing layers of carbide, nickel or ceramics to reload rings and wear surfaces and to improve the thermal barriers of the parts.
• Flame spray or shooping makes it possible to apply layers of 13% chrome, molybdenum, zinc or bronze from a few tenths to several millimeters thick. The operators of the Lorilleux company also master the flame projection of polymer coatings such as Rilsan® Polyamide 11.
• Buffer electrolysis allows the localized deposition of copper, nickel and zinc-nickel for refilling impacts, scratches or parts with contact corrosion problems.
• Grinding makes it possible to precisely adjust the dimensions of the parts after their resurfacing, ensuring perfect compliance with the required tolerances.

To machine parts that are too bulky, difficult to transport or limit operating losses, our teams can intervene directly on your site. For more information on our on-site interventions, see our page.
