• Artificial Intelligence (AI) — From FAIR data practices that bridge raw R&D with AI-powered discovery, to robotic tribometers capable of running 432 experiments in 24 hours, and nanoparticle megalibraries screening 150 million materials on a single chip, AI is beginning to fundamentally reshape how tribological research is conducted.

• Manufacturing — The “Industry 4.0 Flywheel” concept demonstrates how AI-driven continuous improvement can move manufacturers from reactive problem-solving to proactive optimization. The report also covers real-time oil condition monitoring and the growing use of water-based lubricants in precision cold forming operations.

• Thermal Management — Direct immersion cooling is emerging as a critical lubricant application for both EV battery packs and data centers. The report also addresses compressor lubricant challenges, varnish formation, and the role of metalworking fluids in heat dissipation.

• Decarbonization — The report examines renewable base stocks, glycerol-based lubricants performing in forestry, agriculture and hydropower applications, oil life extension through additive replenishment, and the new lubricant formulation challenges posed by hydrogen and ammonia as alternative fuels.

The 2026 Report on Emerging Issues and Trends in Tribology & Lubrication Engineering was prepared by Dr. Neil Canter, FSTLE, CMFS Chemical Solutions, Willow Grove, Penn., in collaboration with the STLE Board of Directors, STLE Editorial & Publications Committee, and with input from more than 10 industry experts. Canter says, “This report highlights four major trends (AI, manufacturing, thermal management, and decarbonization) that are and will influence lubricant development and application now and into the future. In these challenging times, tribologists are well positioned to take advantage of these trends to assist users of lubricants with improving productivity and reducing waste, emissions, and operating costs.”

The 2026 Report on Emerging Issues and Trends in Tribology and Lubrication Engineering is available free to STLE members and available for purchase by non-members for $20 at www.stle.org/2026EmergingTrendsReport. For more information, visit www.stle.org or call (847) 825-5536.
