Study on Tribo-Fabrication in Polishing by Nano Diamond Colloid

Now that nano diamonds can be produced stably at low costs, there are growing needs to explore new areas of applications. This report discusses basic polishing experiments performed on nano diamonds to investigate their frictional and wear characteristics during polishing, and the results been obtained. The authors also propose a new terminology “tribo-fabrication” to mean an area of research on tribological phenomena seen with the interface of workpiece and tool surface in ultra-precision fabrication. These new term as well as the polishing characteristics of nano diamond are discussed.
