Conclusions

  1. 1.

    It has been established that with fall in carbon content the Young's modulus, σtr, and microhardness of titanium carbide decreases.

  2. 2.

    In vacuum friction tests the coefficient of friction of the carbide is directly proportional to its carbon content at temperatures of 20 and 400°C and inversely proportional to it at 1200°C. At 800°C the effect of composition on the coefficient of friction is negligible.

  3. 3.

    The rate of wear of the carbide is proportional to the area of true contact.

  4. 4.

    An x-ray structural analysis has demonstrated that the maxima on curves of physical interference line broadening observed after friction tests at all temperatures correspond to the carbide TiC0.68.
