| Abstract | In the present research, a novel cost-efficient chromium (Cr)-aluminum (Al)-carbon (C) target hot-pressed at 650 degrees C with chromium:aluminum:carbon = 2:1:1 (molar ratio) was applied to fabricate chromium aluminum carbide (Cr2AlC) coatings by the arc ion plating method at room temperature and subsequent annealing. Scanning electron microscopy, X-ray diffraction and transmission electron microscopy were used to characterize the coatings and the target. The results showed that the chromium-aluminum-carbon target mainly comprised chromium, carbon and chromium aluminum compound (Cr9Al17). By arc ion plating with the hot-pressed chromium-aluminum-carbon target and subsequent annealing at 620 degrees C, polycrystalline chromium aluminum carbide coating with minor chromium carbide (Cr3C2) was obtained. The as-prepared chromium aluminum carbide coating was dense and crack-free, and there existed macroparticles in the coating. Transmission electron microscopy observations revealed that the as-prepared chromium aluminum carbide coating exhibited a multilayer structure vertical to the growth direction. The coating possessed hardness and adhesion strength of 8.8 +/- 0.8 GPa and 42 +/- 17 MPa, respectively, which could meet the basic requirement of high-temperature protective coating. |
