1Effect of Spray Parameters on the Splashing of Plasma-sprayed Cast Iron Particles显示文摘To understand the effects of spray parameters on the splashing,cast iron particles were plasma-sprayed onto polished surfaces of aluminum substrate to form single splats.Various plasma arc powers and spray distances were applied to adjust the morphology of the splats which was studied using a field emission scanning electron microscope(FESEM).The experimentalresults showed that the splashing of impinging droplets was significantly restrained for the splats deposited with high arc power(30 k W)and short spray distance(80 mm).This finding would be beneficialto improving the adhesive strength of the coating.邢亚哲 LI Xinghang ZHANG Yong JIANG Chaoping ZHANG Weiwei 2016Journal of Wuhan University of Technology(Materials Science)2016,31,2:2
2Evaluation of Microstructure and Wear Properties of Ti-6Al-4V Alloy Plasma Carbonized at Different Temperatures显示文摘Ti-6Al-4V(TC4) alloys were plasma carbonized at different temperatures(900, 950, and 1 000 ℃) for duration of 3 h. Graphite rod was employed as carbon supplier to avoid the hydrogen brittleness which is ubiquitous in traditional gas carbonizing process. Two distinguished structures including a thin compound layer(carbides layer) and a thick layer with the mixed microstructure of Ti C and the α-Ti in carburing layer were formed during carburizing. Furthermore, it was found that the microstructure and the properties of TC4 alloy were signifi cantly related to the carbonizing temperature. The specimen plasma carbonized at 950 ℃ obtained maximum value both in the hardness and wear resistance.张勇 WEI Qiulan 邢亚哲 JIANG Chaoping LI Xinghang ZHAO Zhiyu 2015Journal of Wuhan University of Technology(Materials Science)2015,30,3:1
3MICROSTRUCTURE AND MECHANICAL PROPERTIES OF ALUMINA COATINGS PLASMA-SPRAYED AT DIFFERENT SUBSTRATE TEMPERATURES显示文摘Alumina coatings are prepared by atmospheric plasma spraying through controlling the substrate temperature during spraying. The changes in microstructure and mechanical properties of the coatings prepared at different substrate temperatures are examined. The hardness and the elastic modulus of the coatings are measured by indentation methods. The results show that interlamellar bonding in the coatings is significantly improved with increasing the substrate temperature. Moreover, long through-thickness columnar grains form in the coatings when the substrate temperature reaches above 430℃. As a result, the cross-sectional hardness and the elastic modulus perpendicular to the coating surface increase with increasing the substrate temperature.Yazhe Xing Chaoping Jiang Hong Chen Jianmin Hao 2011Acta Mechanica Solida Sinica2011,24,5:0
