Measurement of hardness and wear rate of composite materials with an alloy base Nickel-titaniumŲ
Noor Sami, M. Abdulrazzaq, Amar Albaaj
Abstract
In this paper, composite materials based on nickel-titanium alloys, which are reinforced with
fractions of different sizes from a solid material, were prepared. The materials are prepared by
powder metallurgy method, the materials are mixed and then pressed and sintered at an
appropriate temperature, hardness tests and wear rate test are carried out. The results showed the
presence of a reinforcing material with increased hardness of the composite materials compared to
the non-reinforced alloys. The results also showed better particle distribution and higher hardness
with increasing fracture size. As for the rate of wear, it was lower for composite materials compared to the unreinforced alloy due to the increase in hardness, and the rate of wear decreased with the
increase in the size of the fracture in minutes.
