Abstract

Metallic coatings sprayed on ductile substrates play a crucial role in various industries by enhancing tribological properties and extending component durability, particularly in the automotive and aerospace sectors. Quasicrystalline coatings are notable for improving mechanical strength, wear resistance, and corrosion resistance. This study focuses on decagonal-symmetry quasicrystalline coatings produced from Al₆₅Co₁₈Cu₁₇ powder using high-velocity oxygen fuel (HVOF) thermal spraying. The main objective was to achieve a coating predominantly composed of the decagonal-D quasicrystalline phase, as icosahedral-phase quasicrystals often decompose during thermal processing, necessitating costly additional treatments. The results showed that the coatings were mainly composed of the decagonal-D phase, with minor traces of m-Al₁₃Co₄ and B2-Al(Co,Cu) phases, eliminating the need for post-spray treatments. This advancement enhances cost-effectiveness and efficiency while maintaining the desirable properties of quasicrystals, such as high hardness and wear and corrosion resistance. The research concludes that AlCoCu (D) coatings are promising for harsh environments, offering a viable and high-performance alternative for industrial protection.

通过高速氧气燃料 (HVOF) 获得铝钴铜十边形准晶涂层的可行性

喷涂在韧性基底上的金属涂层通过提高摩擦学性能和延长部件的耐用性，在各行各业发挥着至关重要的作用，尤其是在汽车和航空航天领域。准晶涂层在提高机械强度、耐磨性和耐腐蚀性方面效果显著。本研究的重点是利用高速氧气燃料（HVOF）热喷涂技术从 Al65Co18Cu17 粉末中制备十边形对称准晶涂层。主要目的是获得主要由十边形-D 类晶体相组成的涂层，因为二十面体相类晶体在热加工过程中通常会分解，从而需要进行成本高昂的额外处理。结果表明，涂层主要由十边形-D 相组成，并含有少量 m-Al13Co4 和 B2-Al(Co,Cu)相，因此无需进行后喷涂处理。这一进步提高了成本效益和效率，同时保持了准晶体的理想特性，如高硬度、耐磨性和耐腐蚀性。研究得出结论，AlCoCu (D) 涂层有望在恶劣环境中使用，为工业保护提供了一种可行的高性能替代方案。
