This paper reports the synthesis and characterization of Bi-Ti3SiC2 and Ag-Ti3SiC2 composites. Novel composites were designed by adding 5vol% (Ag-5%312Si or Bi-5%312Si), 10vol% (Ag-10%312Si or Bi-10%312Si), 20vol% (Ag-20%312Si or Bi-20%312Si), and 30vol% (Ag-30%312Si or Bi-30%312Si) Ti3SiC2 particulates in the Ag and Bi matrix, respectively. SEM studies showed that Ti3SiC2 particulates are well dispersed...
By now, it is fairly well established that the layered hexagonal MAX phases are thermodynamically stable nanolaminates displaying unusual and sometimes unique properties. These phases are so-called because they possess a Mn+1AXn chemistry, where n is 1, 2, or 3, M is an early transition metal element, A is an A-group element and X is C or N. They are highly damage tolerant, thermal shock resistant,...
Herein we show that dry sliding, in air, in the 25–550°C temperature range, of the novel Ta 2 AlC/20vol.% Ag and Cr 2 AlC/20vol.% Ag composites against Ni-based superalloys (SAs) and alumina led to the formation of steady-state tribofilms whose thicknesses and compositions varied depending on sliding conditions. At elevated temperatures, under both isothermal and thermocyclic conditions,...
The layered M n+1 AC n ternary carbides – MAX phases – Ta 2 AlC, Ti 2 AlC, Cr 2 AlC and Ti 3 SiC 2 were tested under dry sliding conditions against alumina at 550°C and 3N load (for a stress of ≈0.08MPa) using a pin-on-disk tribometer. Ta 2 AlC and Ti 2 AlC exhibited low specific wear rates, SWRs, (≤1×10 −6 mm 3 ...
In this paper, we report on the tribological behavior, at 25 and 550°C of the following layered (MAX phase) ternary carbides: Ti 2 AlC, Cr 2 AlC, Ta 2 AlC, Ti 3 SiC 2 , Ti 2 AlN, Ti 4 AlN 3 , Cr 2 GeC, Cr 2 GaC, Nb 2 SnC and Ti 2 SnC, tested against Ni-based superalloys, SA (Inconel-718 and Inconel-600)...
The tribological performances of the two new composite materials, consisting of the layered ternary carbides (MAX phases), Ta 2 AlC or Cr 2 AlC, and 20vol.% Ag, were investigated in the temperature range from ambient to 550°C against a Ni-based superalloy, SA (Inconel 718) and alumina counterparts. Over the entire temperature range, the wear rates, WRs, during dry sliding against the...
