Approved biomaterials such as stainless steels, CoCr and titanium alloys have a greater tendency to gall when coming in contact with like counterparts. Minimally invasive surgical procedures require instruments that are longer, lighter and with increased mechanical performance. Medthin coatings can significantly reduce or eliminate galling issues and reduce friction between metal on metal surfaces. This eliminates the requirement for lubrication. For example Medthin coatings operate as a dry lubricating surface and offer coefficients of friction lower than if oil was introduced.
