| Abstrakt: |
For all of the dense modifications of boron nitride under conditions of loading by friction upon reaching the critical sliding rate a qualitative change in the frictional characteristics is observed. On the working surface of the abradant a film is formed, which obviously is an indication of transformation of the sphalerite and wurtzite phases into the graphitelike one with subsequent oxidation of it and the formation of low-melting iron borates. |
