Abstract
A cladding layer of Ni3Al matrix composite reinforced with 18 vol. % Cr-carbides was applied by using tungsten inert gas (TIG) welding process on high strength steel substrate. The filler metal as welding wire prepared by horizontal continuous casting process with a composition of Ni- 2.5C-30Cr-9Al-0.02B (in wt. %) is used. A bulk material of NAC-alloy composite with 18 vol. % Cr3C2-particles produced by Hot Isostatic Pressing (HIP) was also investigated as a reference material. The composition of NAC-alloy is Ni-9.87Al-11.63Fe-0.50Mn-0.50Ti-0.2B in weight percentage. The pin-on-disk (POD) tribometer tests were carried out at room temperature in dry sliding condition at a pressure of 2.83 MPa (20N). The results revealed that Ni3Al/ Cr-carbides cladded layer by TIG process improved wear properties significantly with very low values of the friction coefficient (0.13 ± 0.02) and the specific wear rate (0.162 × 10-5 mm3/N·m) as compared to the reference HIP processed composite with the friction coefficient (0.68 ± 0.02) and the specific wear rate (0.908 ×10-5 mm3/N·m) under the same testing conditions. © (2014) Trans Tech Publications, Switzerland.
