A practical demonstration of the low friction properties of Diamond Hard Surfaces Ltd's (www.diamondhardsurfaces.com) Adm tm material. The video shows a hip ball and joint being rotated with minimal force and spinning for almost a minutes , performing many revolutions. It shows the low friction of the Adm amorphous diamond material produced using Diamond Hard Surfaces patented process. The lowest measured friction of the coating is 0.025, as low as PTFE, but hard. The material hardness of the coating is 3500- 4000 Hv.
