  • Frictional stress can damage the machine part in two ways. On the one hand, "fretting corrosion” can occur as surface damage, on the other hand there is a reduction in the fatigue strength of vibratingly loaded machine parts when two metals rub against one another.
  • tribochemically activated particles can emerge from the surface, which react spontaneously with the oxygen in the ambient air or oxygen as the working medium.
  • the "greatest vibrating load in the component” is referred to as the “friction durability" at which no friction fatigue fracture occurs yet.

  • the object of the present invention is to improve the properties and application of layers which protect against wear and corrosion on surfaces or surface areas of machine parts. It should not only be possible to coat titanium materials and the composition of the protective layer should be chosen so that a whole range of application methods can be used, and not just the galvanic deposition as described in the journal Metall Chemistry 11/1982, pages 557 to 560.
