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.

New coatings to support an evolving industry

The transportation industry faces many challenges. APS helps you improve fuel efficiencywhile providing an exceptional driving experience by reducing noise and friction with non-stick coatings. Likewise, we support the transition to electric or hybrid vehicles with coatings implementing insulation or electrical conductivity properties. Finally, we support maintenance workshops in order to repair wearing parts of rolling stock or vehicles thanks to our spray metallization interventions on site or in our workshops.

Our strengths:

• Our tier-1 referencing with demanding customers and our industry certifications allow us to be part of programs such as Formula 1
• A zinc flake dip-spin process for the anti-corrosion treatment of large volumes of parts with reception mats allowing good separation of each part
• Many solutions offering electrical properties in paint spray or thermal spray
• Refilling of wearing parts for maintenance workshops

Formulations specifically developed for the food industry

With the growth of cheaper aluminum-based equipment in the food industry, manufacturers must choose suitable coatings now. APS offers a choice of materials and coatings (fluoropolymers, silicone and Sol-gel) offering a wide spectrum of performance and meeting all your needs: coating life, hardness, food safety, etc. These properties, sometimes contradictory, require optimization of formulations and processes that APS is able to provide you. Metrasur and Lorilleux also offer on-site interventions to repair your equipment (mixers, augers, etc.) quickly while limiting line downtime.

Our strengths:

• Durability of our coatings: Some of our formulations can withstand up to 5,000 cycles per tray
• Excellence in food quality and traceability
• Energy savings by optimizing materials and designs
• Anti-stick characteristics for a reduction in the amount of fat used
• On-site interventions for repair of production equipment

A variety of processes and formulations for demanding environments

The chemical and water treatment industries have particular constraints when it comes to the choice of protective coatings and equipment repair. The APS group companies offer many suitable high-performance coatings, resistant to chemical or atmospheric corrosion, at high temperatures or guaranteeing the absence of unwanted migrations in water. Metrasur and Lorilleux also offer on-site interventions to repair wearing parts damaged by corrosion.

Our strengths:

• Chemically inert coatings to protect metal parts from harsh chemical attack up to 260°C.
• Thermal spray coatings complement the offering in case of extreme temperature conditions or mechanical constraints (cavitation, moving parts) when added to chemical attack.
• On-site repair interventions to limit production stoppages and avoid costly repurchases of new equipment.
