What is PVD Coating for O&G Plunger Durability about?

The study evaluates a duplex coating of plasma nitrided V820 steel and CrAlN for plungers in hydraulic fracturing pumps, demonstrating significant improvements in wear and adhesion properties compared to traditional thermal spray coatings. Laboratory tests showed a 30-fold reduction in mass loss during abrasion tests, and field tests indicated a nearly 300% increase in pumping cycles for the PVD coated plungers. The findings suggest that the duplex treatment enhances the durability and performance of compon
