Summary: Environmental barrier coatings for SiC/SiC composites are limited by the melting temperature of the Si bond coating near 1414 degrees C. Systems without a bond coating may be required for future turbine applications where material temperatures go beyond 1350 degrees C. Enhanced roughness SiC substrates were developed to assess coating adhesion without the bond coating. Two EBCs with different YbMS/YbDS ratios were produced via modified plasma spraying parameters. Coating microstructure, thermal expansion, and modulus were measured for comparison of coating properties. Cyclic steam exposures at 1350 degrees C were performed to assess oxidation resistance. The EBC with increased concentration of Yb2SiO5 secondary phase displayed a higher CTE, which is typically expected to decrease adhesion lifetimes due to an increase in stress upon thermal cycling. Yet, the EBC chemistry with increased Yb2SiO5 concentration was able to experience longer cycling times prior to coating delamination, likely due to interface interactions with the substrate and the thermally grown oxide.

Summary: The optimization of duplex-treatment of thermal oxidation and laser surface texturing was studied to improve the tribological performance of titanium alloys. All duplex treatments showed lower friction coefficient and wear rate compared to thermal oxidation-only treatment. Samples with 10% surface density exhibited excellent tribological performance regardless of the processing sequence. The higher surface density led to increased destruction and adhesive wear of the surface.

Summary: Titanium alloys are essential for lightweight and high-thrust-to-weight-ratio aeroengines due to their low densities and high specific strengths. However, as the thrust-to-weight ratio increases, the temperature in an aeroengine rises considerably above the service temperature of the titanium alloy. Effective design and preparation of the interface structure can enhance the service life and dependability of thermal barrier coatings (TBCs).

Summary: In order to solve the drilling ball phenomenon on PDC bits, wear-resistant Ni-P alloy coating and surface hydrophobic texture are used. Ni-P alloy coating is deposited on the laser-textured (rectangular, linear, and sinusoidal) surface of 42CrMo through electroless plating. The rectangular texture coating with a spacing of 150-200 μm has a maximum contact angle of 133.7 degrees in the wettability of water-based drilling fluid, which is 75.69% higher than that of 42CrMo steel. The anti-mud adhesion and erosion life have also been improved to a certain extent. This research provides important experimental results and theoretical basis for solving the drilling ball problem of PDC bits.

Summary: In this study, La1-xNdxMgAl11-xScxO19 coatings were plasma-sprayed and their high-temperature performance was investigated. The addition of Nd3+ and Sc3+ as dopants improved the properties of the coatings by reducing thermal conductivity, enhancing the thermal expansion coefficient, and maintaining phase stability. The doping also increased adherence between the topcoat/bondcoat. The doped coatings exhibited good mechanical performance and structural integrity at high temperatures and in thermal cyclic fatigue tests. These findings suggest that the doped coatings are promising candidates for advanced thermal barrier coating applications.

Summary: The study aimed to investigate the effects of Ir and Pd additions on the oxidation behavior of PtAl coatings. Results showed that the Ir-modified PtAl coating exhibited better oxidation resistance than both Pd-modified and normal PtAl coatings, as Ir partly served as a diffusion barrier to reserve Al while Pd did not. This study provides important insights for the improvement of PtAl coatings.

Summary: This study analyzed the effect of gaseous atmosphere on an Inconel 625 alloy during Laser Powder Bed Fusion (L-PBF). The results showed that the nature of the gas did not have a clear effect on energy coupling, but gas, especially helium, could modify the surface finish. This modification was beneficial for vertical builds but could reduce surface tensions for inclined and overhanging surfaces. Helium and nitrogen gases showed a moderate benefit on porosity rates at high laser energy, but no detectable differences were observed in the microstructures at the scale considered for the analyses.

Summary: This paper investigates the initial oxidation stages of additive manufactured Rene 65 Ni-based superalloy between 700 and 900 degrees C in air and argon for 48 h, with different building directions and heat treatments. The only factor that impacts the oxidation behavior is the oxidizing atmosphere. The resulting oxide scales are composed of NiCr2O4 and Cr2O3 at 700 degrees C, while at 800 and 900 degrees C, an external Cr2O3 layer forms on top of an internal layer of alpha-Al2O3 due to lower oxygen partial pressure underneath the chromia layer.

Summary: A study was conducted on Laser Powder Bed Fusion Inconel 718 to investigate the influence of defects and microstructure on high-cycle fatigue life. It was found that printing orientation had minimal effect on fatigue life, with most failures attributed to lack of fusion defects. The influence of defects was greater at 20 degrees C compared with 650 degrees C. Hot isostatic pressure treatment improved fatigue resistance. Natural cracks propagated in a similar manner to long cracks.

Summary: The VHCF behavior of a Ni-based single crystal superalloy treated by different processes was studied. HRS and LMC samples showed cracks initiating from casting pores surrounded by a rough zone. The rotation of γ' within the rough zone was related to the operation of {1 1 1}(110) and {111}(11 2) slip systems. HRS+HIP specimens exhibited the best VHCF property with failure mainly occurring on the surface, while LMC process increased VHCF durability similar to HIP treatment, especially under low loading conditions.
