[Case Study] Improvement of Wear Resistance in the Mechanism of Heat Recovery System

Dramatically improve the performance of the underlying PVD coating! Case study in exhaust heat recovery systems for HV vehicles.

We would like to introduce a case that solved the problem of "wear occurring at the sliding parts of stainless steel in high-temperature environments." The sliding parts were made of SUS materials, and applying lubricants was difficult. We considered nitriding treatment and hard coatings such as DLC, but we could not achieve satisfactory results. Therefore, instead of simply applying a PVD-type film, we significantly improved the performance of the underlying PVD coating by combining it with a high-temperature dry lubrication coating that excels in initial bedding and wear resistance. Our special pretreatment ensured the adhesion of the lubrication coating on the PVD. [Key Points of Problem Solving] ■ Sliding friction between stainless steel tends to cause seizure and galling. ■ Our wear-resistant coating quickly forms an ideal sliding surface and can be applied to areas under thermal load in high-temperature environments and high-performance engines. *For more details, please refer to the PDF document or feel free to contact us.
