Summary: Driven by sustainability and cost concerns, there is a growing interest in power generation using renewable sources, particularly biomass and waste. Erosion, rather than corrosion, can be a major issue in power plants utilizing pure biomass with less corrosive elements. This study evaluates complex carbide-based coatings to protect against erosion and prolong the service life of boiler components. Comparisons are made between the performance of a hand-held high-velocity air-fuel (HVAF) spray gun and the current high-velocity oxy-fuel (HVOF) deposition method.

Summary: This paper investigates the hydro-abrasive erosion behaviors of carbide-based cermet coatings sprayed by high-velocity oxygen-fuel (HVOF) in simulated seawater slurries. The WC-Ni coating exhibits worse corrosion resistance but superior hydro-abrasive erosion resistance compared to the Cr3C2-NiCr coating. The hydro-abrasive erosion resistance of the WC-Ni coating is less affected by flow velocity and sand concentration, while the Cr3C2-NiCr coating is highly influenced by these factors. Higher flow velocity and sand concentration both contribute to the degradation of the coatings' hydro-abrasive erosion resistance, with flow velocity having a greater effect.

Summary: High-velocity oxygen-fuel spraying was used to deposit WC-10Ni (WN) and WC-10Co-4Cr (WCC) powders as coatings on a 1Cr18Ni9Ti stainless steel substrate. Despite having higher hardness and elastic modulus, the WN coating exhibited better resistance to corrosion in NaCl medium compared to the WCC coating. Both WN and WCC coatings showed an increase in volume loss rates as flow velocity in NaCl medium increased, and the corrosion mechanisms were compared and revealed.

Summary: UHMWPE is a material resistant to acids, alkalis, and radiation, which makes it attractive for obtaining multifunctional coatings. However, difficulties such as low thermal conductivity and high viscosity are associated with the process of obtaining UHMWPE-based coatings. This study explores the possibility of overcoming these technological problems and proposes a new deposition method with preliminary heating of the powder in a fluidized bed. The obtained results demonstrate the potential to achieve higher quality coatings.

Summary: The effects of sand concentrations and flow velocities on the hydro-abrasive erosion behavior of carbide-based cermet coatings were studied. The WC-Cr3C2-Ni coating exhibited better resistance to hydro-abrasive erosion compared to the Cr3C2-NiCr coating. Higher sand concentrations and flow velocities caused more severe hydro-abrasive degradation for both coatings, with flow velocity having a greater influence on erosion resistance than sand concentration.

Summary: In this study, two cermet coatings were manufactured and their resistance to cavitation-silt erosion in simulated sea water slurries was investigated. The results showed that the Cr3C2-25(NiCr) coating had worse CSE resistance compared to the WC-10(Ni) coating, and its resistance was more affected by sand concentration and flow velocity. Both sand concentration and flow velocity had a positive effect on the CSE damage for both coatings, but sand concentration had a greater influence. The deterioration mechanisms of the coatings under different sand concentrations and flow velocities were also compared and revealed.

Summary: Hydrophobic PTFE coatings with varying thicknesses were tested for cavitation erosion resistance on hydro-machinery SS410 steel. The coating with a maximum thickness of 121 μm exhibited the highest resistance, attributed to its lowest fracture toughness and better cushioning effect. Overall, thinner PTFE layers showed increased contact angle but also higher cavitation erosion.

Summary: This paper presents an experimental study on the influence of air swirl vane angles on pollutants in a heavy oil fuel fired furnace. The results show that vane angles of 45 degrees and 30 degrees emit the least HC and CO, whereas a vane angle of 90 degrees emits the most. A vane angle of 45 degrees results in the lowest NOx emission. Furthermore, for complete combustion, the secondary air entry area should be twice the primary air entry area in the novel burner.
