Deloro Wear Solutions provides wear components for heavy-duty diesel truck engines, turbochargers and EGR (Exhaust Gas Recirculation) units. In addition, we also provide a range of wear solutions for a number of more widely transportation-related applications.

Deloro Wear Solutions supplies a broad range of products to the automotive and truck industry. We manufacture components that allow engines to run longer and more efficiently. They also help ensure the engines meet the stringent emission norms and reduced consumption demands that are being imposed on the industry. Our alloys are proven to reduce engine downtime, and are allowing manufacturers to offer extended reliability and warranties to the end user. 

Possible applications for Tribaloy®-surfaces and components in the automotive market are divers. In diesel engines hot corrosion is a particularly acute problem, especially if low grade fuels are used.

The combination of surrounding conditions, that make the use of Tribaloy’s® necessary are high temperatures up to 900°C and above, corrosive agents and intense mechanical loads and stresses. Those are found, i.e., in the Valvetrain, where hot, corrosive gases meet fast cyclic and frequent motion. The exhaust valves of internal combustion engines are subject not only to mechanical degradation from impact and sliding stresses, but also hot corrosion by the products of combustion.

To maintain efficient engine operation, it is vital that engine valves are protected against such wear. Stellite 6, Stellite F and Tribaloy® are most common alloys in the automotive valve industry. We have a long established track record in the industry and our product offering continues to grow as we develop new products, materials and process technologies.

More of our components are commonly found in Turbochargers, where actuators move and steer precisely, in the exhaust tract and exhaust gas recirculation systems (EGR). In all these areas, from combustion engine until exhaust pipe, you can find castings as valve seat rings, as Actuator rods or bushings and coatings on shafts, valves and pistons. Shafts and valves are mainly coated with Stellite 6, Stellite F and T-800 alloys using both, PTA or HVOF processes, and they run against or in rings and bushings made out of T-400 in investment or resin shell casting processes. 

Our alloys are employed for the above applications and in those environments because they provide secure durability for components that have to function under extreme conditions for lifetime and prevent costly rework or substitution. This is one of the key the reason why most components appear in Trucks, light and heavy duty commercial vehicles with guaranteed and expected mileage above the million. 

In addition to that you will find our components in the high performance engines and drivetrains of very ambitious racecars. More recently, passenger cars employ them because of the continuously rising demands of increased-power rated downsized engines. They only function because of materials with extremely durable materials like our Tribaloy’s®. 

Our products are specifically designed to help manufacturers meet the demands for higher performance engines imposed by the market. As the need for further improvement in engine efficiency develops, we are here to support the industry with engineered solutions and alloy expertise that will meet the most demanding of applications.
