“…TiO 2 oxide film on the surface of titanium alloy is easy to peel off, which nearly failure protects substrate surface. The plastic shear resistance and work hardening performance are poor, which is not enough to resist the friction and wear caused by relative motion [6]. Therefore, it is necessary to coat titanium surface to improve wear resistance.…”

In situ synthesized TiN and TiB reinforced metal matrix composite coating was fabricated on Ti-55511 by laser cladding with Ti-55511/BN powder mixture (2 wt-% BN). Results indicated that coating was mainly composed of TiB, dendrite TiN and α phase. The diameter of small-sized hollow tubular TiB was less than 400 nm, and the width of the other rod-shaped TiB was less than 1 μm. The flower-like structure formed during solidification consisted of TiN dendrite in centre and rod-shaped or hollow tubular TiB at edge. Coating had high hardness (540 HV) due to formation of TiB and TiN. After direct aging (600°C/5 h/AC), the hardness of coating and HAZ increased to 660 and 450 HV respectively because of nano-scaled α phase precipitation. In the friction and wear test, the weight loss of the coating was only 62% of that of substrate, which further reduced to 47% after aging.

“…Tribology involves contacting surfaces with relative movement and affects many aspects, such as manufacturing, automobile, and railway [1][2][3]. In the past, tribology studies mainly concerned on the coefficient of friction (COF) and wear loss of materials tested under different tribological conditions [4][5][6]. With the extensive learning on tribology, studies on microstructure evolution of worn surface and (or) subsurface caused by plastic strain have attracted much attention [7][8][9][10].…”

This study focused on the tribological performance and microstructure evolution of T20Z alloy after dry sliding in air and vacuum. After the tribological tests, normal load and sliding velocity were considered to be optimized based on specific wear rates using Taguchi technique. The results of S/N ratio showed that the optimization of the parameters was 10 N, 0.59 m s −1 for obtaining the minimum wear rates in both air and vacuum. Also, the worn surface and cross-section of T20Z alloy as well as wear debris and counterpart steel balls were analyzed by scanning electron microscopy. Raman spectrometer was performed to further analyze the worn surface. The topography of wear scar was observed using a three-dimensional optical profilometer. The microstructure evolution of T20Z alloy was analyzed by transmission electron microscopy. The results showed that the wear mechanisms in air varied from abrasive wear to delamination wear and severe abrasive wear, and the grain size was finally refined to nanoscale. In vacuum, however, wear mechanisms changed from slight abrasive wear to delamination wear and severe plastic deformation, and only the β phase was deformed.
