Arolled mild steel wascoated byconductive polymers( polyaniline/ MMPand polyaniline/HCSA) andthenim mersedin hot water(50 ℃) fordifferenttimesforstudytheadhesion ofcoatings.It wasfound thatthe adhesion tendsto decrease over time. Thestudyshown that onebrittle and porous Fe3 O4 layer formed between conductive polymercoating and steelsub stratein a moistenvironmentand, asa result, decreased thecoating adhesions.

腰果壳油摩擦粉是树脂基摩擦材料中广泛应用的摩擦性能调节剂.通过改变摩擦材料中腰果壳油摩擦粉组分含量,研究腰果壳油摩擦粉对树脂基摩擦材料的理化、机械、摩擦磨损及制动噪声性能的影响.结果表明:随着摩擦粉含量增加,摩擦材料的气孔率、压缩变形量增大,pH值、密度、硬度和冲击强度减小.通过执行SAEJ2521和SAE J2522程序进行台架实验,表明摩擦粉的加入可提高并稳定摩擦材料的摩擦因数,同时有效降低刹车片制动过程噪声发生概率.摩擦材料中摩擦粉添加量7%(质量分数)时,摩擦材料冲击强度3.36 k J/m2,名义摩擦因数0.36,平均磨损厚度0.53 mm,噪音发生概率为14.4%,刹车片综合性能最佳.
