The results show that the brush-plating coating is even and compact from section plane with good toughness and adhesion. The microhardness of the coating is 230.6HV0.5 which is 3 times of cast aluminium substrate. The wear resistance of the coating is 3 times of cast aluminium substrate. But the friction coefficient of the coating is 0.70 which is more high than that of the substrate, which is favorable for the fixed conjugate between the axis sheath and the axis seat of the gear-box.
结果表明,镀层厚度分布均匀、致密,镀层与基体界面清晰,未出现氧化物夹层,镀层的韧性和结合强度均较好;测得碱性铜及铸铝基体的显微硬度分别为230.6、74.2HV0.5;碱性铜的镀制使基体表面显微硬度及耐磨性均提高了2倍多,磨损状况明显改善。

A schematic model was proposed to illustrate the occurrences of various lithologies and lithofacies associations. The erosional surfaces on siliciclastic mudstones, funnel-shaped structure, and the exhuming of massive cold-seep carbonates exposed might have been occurred concurrently during a tectonic unstable time in SW Taiwan. The deposition of fossiliferous mudstone interfingered with the conglomerate lithofacies, and represented the rapid facies transition from siliciclastic (non-carbonate) into carbonate environment.
