Trans. Nonferrous Met. Soc. China 22(2012) s876-s880 Effect of pulse time on surface characteristics and corrosion resistance during pulse electrochemical polishing Young-Bin KIM1, Jeong-Woo PARK2 1... 21 May 2012; accepted 13 August 2012 Abstract: Pulse electrochemical polishing (PECP) was used to improve the mechanical properties, such as surface roughness and corrosion resistance, of conductive......
is applied to polishing a thin and long cylindrical bar. A micro-finishing film and a lapping film were used as abrasive films. Al2O3 grains or SiC grains were used as abrasives. The surface roughness of a polished workpiece was measured using a stylus-type surface-roughness measuring instrument. As a result, the conditions to improve the polishing surface efficiently include high values......

Effect of Surface Polishing Treatment on the Fatigue Performance of Shot-Peened Ti–6Al–4V AlloyZ.G.Liu1,T.I.Wong2,W.Huang1,N.Sridhar1,S.J.Wang21. Institute of High Performance Computing A*STAR2.... Experiments reveal that the fatigue life of Ti–6Al–4V is improved by the shot peening process, and the surface pre-peening polishing. The combination of pre-and post-peening polishing treatments......
SUS304不锈钢表面抛光缺陷原因分析及改进措施茅卫东1(1.上海市宝山钢铁股份有限公司)摘 要:对SUS304不锈钢抛光"点状"缺陷解析表明,缺陷主要是由于Al2O3等脆性夹杂物在抛光处理后部分脱落而形成.控制钢水T[Al],提高AOD炉渣还原性能,喂SiCaBa线处理等夹杂物控制技术,实现了板坯总[O]从45.1μg/g下降为30.7μg/g,而且夹杂物变性,改善了表面抛光"点状"缺陷.关键词:SUS304不锈钢； 点状缺陷； 夹杂物； 抛光......
compared with as-aluminized bond coats. However, the wavelength of TGO undulations shows a little increasing trend. From further study, the polishing treatment bond coats show better TGO adherence and lower alumina growth rate. Key words: platinum; aluminide bond coats; high temperature oxidation; polishing treatment ......
