高能微弧合金化制备Ni3Al(Cr)涂层及其高温抗氧化性能
Preparation of Ni3Al(Cr)Coating by High Energy Micro-arc Alloying and Its High Temperature Oxidation Resistance
摘 要
采用高能微弧合金化技术在K3合金表面制备了Ni3A1(Cr)涂层;对其制备工艺进行了优化,并对涂层在1 000 ℃下的氧化行为进行了研究.结果表明:用高能微弧合金化技术可在K3合金表面制备出微晶涂层,阳极材料采用铸态Ni3Al(Cr)金属间化合物所得涂层能够与基体形成冶金结合;在1 000 ℃下,所得涂层因晶粒细化可以在较短时间内生成连续保护性富铝/铬氧化膜,而铸态电极和K3合金不能形成连续致密的氧化膜,因此所得涂层比铸态Ni3Al(Cr)电极和K3合金具有更好的抗氧化性能,并且NiO和尖晶石的生成量也减少.

Abstract
Ni3Al(Cr)coating was prepared on the surface of the K3 alloy by high energy micro-arc alloying process.The preparation process was optimized.The oxidation behavior of the coating at 1 000 ℃ was analyzed.The results show that the microcrystalline coating could be obtained on the K3 alloy by high energy micro-arc alloying process.The coating obtained by using as-cast Ni3Al(Cr)intermetallic compound as electrode material could get a metallurgy bonding with the matrix bonded.The coating could form a continuous protective Al/Cr-rich oxide film in a shorter time because of the grain refinement,while the cast electrode and K3 alloy could not form continuous and compact oxide film.The coating had better oxidation resistance than the as-cast Ni3Al(Cr)and K3 alloy,while the formed amount of NiO and spinel decreased.
