Microstructure and property evolution of high-entropy rare-earth silicate T/EBCs during thermal aging

With the increasing service temperature of aeroengines, the development of thermal/environmental barrier coatings (T/EBCs) has been considered to be a great challenge, which requires high-temperature stability and excellent thermal and mechanical properties. In this work, high-entropy design was adopted to change the crystal structure of rare-earth monosilicates used for T/EBCs. The microstructure evolution, thermal and mechanical properties of the plasma-sprayed (Lu_0.25Yb_0.25Er_0.25Y_0.25)₂SiO₅ and (Lu_0.2Yb_0.2Er_0.2Ho_0.2Y_0.2)₂SiO₅ coatings before and after thermal aging at 1350°C for 50 h were investigated. Results showed that the as-sprayed coatings exhibited dense structure with amorphous and decomposed phases. The change of microstructure like amorphous crystallized and defect healing occurred after thermal aging, which had obvious influence on thermomechanical properties. Compared with single-component RE₂SiO₅ (RE = Yb, Er, Y) coatings, the thermal-aged high-entropy coatings exhibited lower thermal conductivity, similar thermal expansion coefficient, and better toughness. The work will provide a foundation for the design and application of T/EBCs materials.

The investigation of adhesion and fatigue properties of TiN/TaN multilayer coatings

TiN/TaN multilayer coatings exhibit excellent mechanical properties when compared to single layer nitride coatings. In this study, TiN/TaN multilayer coatings were deposited on Mo-alloy and W-alloy substrates by CFUBMS. The structural and mechanical properties of coatings were analysed using XRD, EDS, SEM and a micro-hardness tester, respectively. To determine the adhesion and fatigue behaviour of the coatings were performed a scratch test in two modes that a standard mode with progressive loading and sliding-fatigue multimode operation with unidirectional sliding, respectively. A microscope was used to characterize adhesion and fatigue failures. The structural, mechanical, adhesion and fatigue properties of TiN/TaN multilayer coatings significantly changed depending on the substrate.

Development of polyorganosilazane–silicone marine coatings

The objective of the present work is the development and characterization of marine coatings based on polyorganosilazanes (PSZ). Two types of coatings containing silicone oils and biocidal compounds were investigated as anticorrosive and antifouling coatings. The flexibility, hydrophobicity and adhesion properties of the PSZ-based coatings on aluminum substrates were studied. Static immersions in natural seawater were investigated to evaluate the antifouling performances of these coatings. The corrosion properties were studied by salt spray tests. Results demonstrated that coatings based on silicone oils appeared to be the most efficient coatings in terms of antifouling and anticorrosive properties. Ten-month antifouling efficiency was revealed for biocide-free polydimethylsiloxane-based PSZ coatings in natural seawater static immersion. The adjunction of dicopper oxide as biocidal pigments was shown to decrease the stability in cans of the corresponding paints and therefore decreasing the flexibility of coatings. In addition, this pigment affected badly the anticorrosive properties of the coatings together with a short antifouling efficiency time. Thus, the silicone oil-based PSZ displayed remarkable advantages in addition to their dual antifouling and anticorrosive properties which are the absence of biocidal compounds released in marine environment and the absence of volatile solvent.     

Synthesis and characterization of polyurethane coatings derived from polyols synthesized with glycerol, phthalic anhydride and oleic acid

Polyester polyols, with various oleic acid contents were used in the preparation of polyurethane (PUR) coatings. The polyols were designated as Alk28, Alk40 and Alk65, in which 28, 40 and 65 represents the percentages of oleic acid in the respective formulations. The physical properties of the polyols such as acid value and hydroxyl value have been determined and the infrared (IR) spectroscopic analysis of the polyols is reported. The polyols were reacted with aromatic isocyanate (toluene 2,4-diisocyanate, TDI) to form PUR coatings. The effects of varied NCO/OH ratio and oleic acid content of polyols on physical properties of PUR coatings on mild steel panel were determined. The characterization of PUR coatings carried out by IR spectroscopic analysis and physico-chemical properties such as drying time, pencil hardness, adhesion properties, solvent resistance and corrosion/chemical resistant determination were reported. The coatings obtained from polyol Alk28, exhibits the best overall properties followed by Alk40. PUR coatings from Alk65 were softer. As the NCO/OH ratio of the coatings increased, there were progressive increases in mechanical and anticorrosive properties for all the coatings. Overall, these studies showed that the material holds promise for use as effective surface coating compound by designing the formulation of the desired performance.
