摘　　要：借助XRD、纳米压痕、SEM和划痕仪研究了采用阴极弧制备技术在硬质合金基体上沉积的(Cr,Al)N涂层的显微组织和力学性能。研究表明:面心立方结构的(Cr,Al)N涂层由晶粒尺寸分散的柱状晶晶粒组成;(Cr,Al)N涂层的硬度为31.7 GPa;与硬质合金基体的结合强度约为55 N。The microstructure and mechanical property of the cathode Arc （Cr, Al）N coating grown on cemented carbide substrates has been characterized by using X-ray diffraction （XRD）, nano-indentation, scanning electron spectroscopy （SEM）, scratcher. Results show that （Cr0.28,Al0.72）N coating is composed of columnar crystallites with different grain size. The hardness of （Cr0.28,Al0.72）N coating is 31.7 GPa and the cohesion of （Cr, Al）N coating with cemented carbide substrate is 55 N.
