Effect of Surface Roughness on Improved Lubricity under an Ironing Condition Using a Synthetic Mica-Organic Intercalation Compound

It is well known that the surface roughness of metal substrates considerably influences the tribological properties of solid lubricants. In this study, the surfaces of metal substrates were modified by wet-blasting and polishing, and the lubrication performance of synthetic mica-organic intercalatio...
