High-Temperature Solid Particle Erosion Characteristics and Damage Mechanism of Alxcocrfenisi High-Entropy Alloy Coatings Prepared by Laser Cladding

Shiyi Zhang Bin Han T.M. Zhang Yuhua Chen Jianqiang Xie

The solid particle erosion effects on AlxCoCrFeNiSi high-entropy alloy coatings (HEAcs) prepared by laser cladding under different erosion conditions were investigated. Furthermore, the transformation of the microstructure and properties of the prepared HEAcs under high-temperature conditions and the effect of oxidation on erosion behavior were analyzed. The results show that the hardest Al1.0 HEAc (711 HV0.2) presents typical brittle erosion characteristics, as fracture toughness deteriorates with increasing Al content. When the erosion temperature reaches 700 Â°C, the erosion rate decreases due to precipitation enhancement and oxidation affecting the erosion behavior.

Effect of Chlorine Salt Content on the Microstructural Development of C-S-H Gels and Ca(OH)2 at Different Curing Temperatures

Freshwater resources are scarce in coastal areas, and using seawater as mixing water can alleviate the scarcity of freshwater resources. However, the presence of chloride ions in seawater affects the generation of hydration products and the durability of concrete structures. In order to investigate the effect of hydrated calcium silicate (C-S-H) gel and calcium hydroxide (CH) generation in seawater-mixed cement pastes under 50 °C curing, their microscopic morphology was investigated using differential scanning calorimetry analysis, X-ray diffraction (XRD), and scanning electron microscopy (SEM). The relationship between the amount of C-S-H gel and CH production and the amount of chloride ion dosing, fly ash dosing, and the age of curing were investigated. The degree of influence between hydration products and influencing factors was analyzed using the grey correlation analysis. It was shown that 50 °C curing promoted the hydration reaction and generated more hydration products compared with ASTM standard. The content of C-S-H gel and CH increased with chloride dosage. The content of C-S-H gel increased by 13.5% under 50 °C curing compared with the control group at a chloride dosage of 1.3%. Fly ash is rich in active SiO
