Table 1: Results of mechanical properties of materials Content Material Displacement of fracture (mm) Strength (MPa) Elongation (%) Alloy with carbon powder 1.654 288.360 6.615 No carbon alloy 0.650 292.879 2.601 Fig.2: Tensile displacement curve The curve had shown that larger tensile, the longer platform.
The slip lines of material could be seen in the B region of Fig.3(c).
Fig.4 Surface morphology of alloy (SEM) (b) (a) Fig.5 EDS analysis of alloys Conclusions and acknowledge The conclusions are as follows: (1) Adding a certain size carbon powder can effectively enhance elongation of materials and get a alloy with better ductile, but its strength need to be improved

Interest in zirconia-based ceramics is based on high crack resistance and low setting ability in comparison with most ceramic materials.
Powders of superhard materials and carbon nanotubes are used [8, 9].
Materials and Methods Samples were made in the form of short rods (fingers) with a square section of 5x5 mm and a length of 5 ... 15 mm.
Running-in is one of the important indicators of the tribological properties of materials, during which optimization of the micro geometry and physico-mechanical properties of the surface layers of the contacting materials occurs.
Tribological parameters are influenced by three groups of factors: values that determine the level of external influence on the tribosystem: p - contact pressure, sliding speed, temperature; physical and mechanical properties of materials, of which the most important are the quantities that determine the properties of the surface layers of the contacting materials: elastic modulus E, hardness H, and for brittle materials such as ceramics - stress intensity factor K1c; micro geometry of friction surfaces.
