Description
Michal Krbata and co-authors compare slippery coatings in 2026 for a high-grade gear steel. Three commercial fluoropolymer coatings were sprayed on the steel and rubbed against a ball under dry sliding at several loads. Such coatings promise low friction for parts that cannot use oil.
All three cut friction by roughly four-fifths compared with bare steel. One coating was hardest and wore least, losing almost no material even at the highest load. Another gave the lowest friction but deformed under load, and the third cracked and wore more. Cross-section views confirmed the steel showed through in places. The study ranks the coatings for dry-running machine parts.
