为探究酸性盐雾腐蚀对铝氮化硼（Al-BN）涂层可磨耗行为的影响，开展了酸性盐雾腐蚀192 h前后大气等离子喷涂制备Al-BN涂层的组织结构、表面硬度、结合强度和可磨耗性能的对比研究。结果表明：经过酸性盐雾192 h腐蚀后，Al-BN涂层表面形成了由Al，Al₂O₃，NaCl，BN组成的厚度约为300~350 μm的腐蚀致密层。相较于腐蚀前涂层，该腐蚀致密层的平均硬度与平均结合强度方差增大，在刮削过程中部分弱结合部位易发生刮离，并黏附于对偶叶片摩擦面，造成Al-BN涂层的进给深度比（incursion depth ratio，IDR）值由酸性盐雾腐蚀前的（11.43±0.46）%转变为酸性盐雾腐蚀后的（-12.02±0.38）%，导致Al-BN涂层的可磨耗刮磨机制由塑性变形、黏着磨损混合形式转变为塑性变形、黏着磨损、刮离黏附混合机制，摩擦因数由腐蚀前0.34±0.02提升至0.55±0.03。由此可知，酸性盐雾腐蚀对Al-BN涂层的可磨耗性能造成了不利影响。

To explore the influence of acid salt spray corrosion on the abradability behavior of Al-BN coatings， the microstructure， surface hardness， bonding strength， and abradability of Al-BN coatings prepared by atmospheric plasma spraying before and after acid salt spray corrosion for 192 h are investigated.The results show that after acidic salt spray corrosion for 192 h， the surface of the Al-BN coatings forms a corrosion dense layer composed of Al， Al₂O₃， NaCl， and BN with the thickness of about 300-350 μm. The variance of average hardness and average bonding strength of the corrosion-dense layer increases compared to the as-sprayed coating. During the scraping process， the weak bonding areas of the corrosion-dense layer are prone to scraping off and adhere to the friction surface of the dual blade， which causes the incursion depth ratio（IDR）values of the Al-BN coatings to change from （11.43±0.46）% before acid salt spray corrosion to （-12.02±0.38）% after acid salt spray corrosion， resulting in the abradability scraping mechanism of the Al-BN coatings changing from the mixed form of plastic deformation and adhesive wear to the mixed mechanism of plastic deformation， adhesive wear， and scraping off adhesion， the friction coefficient increasing from 0.34±0.02 before corrosion to 0.55±0.03. Therefore， the acid salt spray corrosion has a negative impact on the abradability of Al-BN coatings.
