Friction and wear properties of self-lubricating chromium plating based on an organic sulfonic acid bath were investigated. The chromium plating film produced using the organic sulfonic acid bath has fine cracks: about five times as many as the plating film from the Sargent bath. Its hardness after heat treatment at 200 ℃ is also high: approximately 900 HV0.2. Furthermore, the F/Cr atomic ratio, which is a rough guide to the amount of PTFE resin adhering to the surface, is high: approx. 3-4. The self-lubricating chromium plating films based on the organic sulfonic acid bath exhibit a stable low coefficient of friction under a load of 4.9 N at a ball-on-plate friction test with a 10 mm diameter Al₂O₃ ball. It remains below 0.2 after 10,000 sliding cycles. The self-lubricating chromium plating films based on the organic sulfonic acid bath not only maintain the low friction coefficient, but also have low aggression towards the mating material, even under high loads. The films also have excellent wear resistance.

Characterization of the friction and wear properties of micro-textured self-lubricating chromium plating surfaces composited with PTFE resin on a surface during sliding were investigated. Surface factors that achieved the low friction coefficient of 0.1 in sliding between a micro-textured self-lubricating chromium plating film and an iron ball（SUJ2）under a 9.8 N load were the following: The exposed area of chromium was less than 80%. For chromium plating peaks of 5 μm or greater diameter, the density was higher than 2,000 peaks/mm². The F/Cr atomic ratio, which is a rough guide to the PTFE resin amount, was more than 2.

When the optimized micro-textured composite film was slid against an iron ball, the friction coefficient was stable, approximately 0.1, with little dependence on load. After 10,000 sliding cycles, the films were about 1/100th less aggressive to the iron ball than conventional Cr films.
