Summary: Ti and Ti-based alloys are commonly used in aerospace and automotive components, but face challenges in wear resistance at elevated temperatures. The study found that Ti-xTiC composite coatings exhibit improved friction and wear performance compared to baseline Ti coatings, with Ti-35%TiC showing the best overall performance at 575 degrees C. The tribological behavior was attributed to the formation of stable oxide layers on the wear surfaces containing TiO2, WO3, and CoWO4.

Summary: In this study, a mechanically alloyed AlNiCoFeCr high entropy alloy (HEA) was used to develop metal matrix composite (MMC) coatings. The coatings, consisting of AlNiCoFeCr and 30 wt % TiB2, were fabricated using the solid-state cold spraying (CS) technique under low pressure and temperature conditions. The effects of compressed air flow temperature and pressure on the structure and mechanical properties of the coatings were investigated. The CS process retained the phase composition and nanostructure in the coatings, and increasing the pressure led to a refinement in the coating structure and an increase in the fraction of TiB2 particles. Increasing the temperature to at least 300 degrees C improved the deposition efficiency and properties of the coatings. The coatings fabricated at a spraying temperature of 450 degrees C and a compressed air flow pressure of 0.9 MPa exhibited a good combination of high microhardness and sufficient indentation fracture toughness.

Summary: Metal matrix composites reinforced with WC particles and Co or Ni matrices are known for their unique combination of hardness, toughness, and superior wear performance. This study focused on Ni-WCNi composite coatings and found that coatings with higher WC fill ratios displayed better wear resistance due to the uniform distribution of WC particles and shorter mean free path reducing adhesive wear. However, at higher loads, subsurface crack propagation at WC particle interfaces led to a reduction in the protective role of mechanically mixed layers. Scratch tests were used to qualitatively compare coating cohesion strengths and correlate them to wear properties.

Summary: This study investigated the friction and wear behavior of three materials commonly used in industrial bearing applications: a Sn-based Babbitt, polytetrafluoroethylene (PTFE), and a polyether ether ketone (PEEK) composite. The effects of load and sliding velocities on wear rates were evaluated by regression analysis, with a focus on the relationship between wear and materials mechanical properties. The ranking of wear performance correlated most strongly with the ratio of hardness to reduced modulus, with implications for estimating oil film thickness in lubrication regimes.

Summary: Ti6Al4V-TiC metal matrix composite (MMC) coatings were cold sprayed using spherical and irregular Ti6Al4V powders with plasma gas atomization and the Armstrong process, respectively. Composite coatings deposited using irregular powders exhibit higher ceramic retentions and lower porosity compared to those made with spherical powder. In wear tests, irregular powder composites showed resistance to abrasive wear mechanisms with lower coefficients of friction and wear rates due to the presence of islands of tribolayers, while increasing ceramic content led to even lower wear rates and continuous tribolayer formation at higher loads. The formation of tribolayers resulted in coarser-grain microstructures in the worn subsurface, indicating less stress transfer and lower wear rates.

Summary: In this study, two Co-based Tribaloy powders were coated on mild steel substrate using high-velocity oxygen fuel (HVOF) spraying. The microstructure and distribution of Laves phases in the coatings were investigated. It was found that Co3Mo2Si and Co3Mo were the main constituents of the intermetallic Laves phases in the sprayed coatings. The volume fraction of Laves phases in the coatings was significantly lower compared to similar alloys due to high cooling rate and solidification in HVOF. The Laves-free solid solution exhibited a nano-crystalline microstructure with similar local hardness to the Laves phases.

Summary: The tribological behavior of MoS2 and WS2 transition metal dichalcogenide (TMD) spray coatings in low-viscosity hydrocarbon environments was studied. The coatings reduced friction on steel surfaces across all test conditions, with the largest reductions observed in dry nitrogen and dodecane environments. The reduced oxidation and uninhibited sliding of TMD sheets were identified as the main reasons for the friction reductions in dodecane.
