Volyns'kyj B. The Scratcch - metod of Determining of Tribological Properties of a surface

The method of determining of tribological properties by scratching the surface has been elaborated. It was called the scratch-method.Mechanics of contact interaction of the hard four edge diamond pyramid with a plastic surface. When pressing and scratching as a basis of the scratch-method has been studied. The device has been created and methods of determining the limit of the contact strength of the surface. When scratching have been worked out.The study of surfaces of 16 various materials and coatings has been fulfilled.Regularities of the movement of the pyramid at the shift depending on the degree of strengthening material have been found. The scratch-method is developed and used for valuing of the quality of the thin hard anode sparking coatings of duralumin D16T.
