Received 15 July 2007; accepted 10 September 2007 Abstract: Nickel coating deposits with better ductility on a lower carbon steel sheet were produced by electrodeposition method and the electrodeposited......
Effect of Catalyst on the Formation of Silica Coating on Nickel Substrate by Sol -Gel Processing Ali Ghasemi1,Ali Ashrafi1,M.A.Golozar1,F.Ashrafizadeh1 (1.Materials Engineering Department, Isfahan University of Technology, Isfahan, Iran) 摘要:In this research work silica coating was produced on nickel substrates by a sol-gel process. In order to increase the rate of hydrolysis and to reduce......
SiC Nanowires Toughed HfC Ablative Coating for C/C CompositesHejun Li,Yongjie Wang,Qiangang Fu,Yanhui ChuState Key Laboratory of Solidification Processing,Northwestern Polytechnical University摘 要... reaction before HfC coating.SiC nanowires grew randomly and had good combination with HfC coating.SiC nanowires toughed HfC coating had lower linear and mass ablation rates than original HfC......
control. This demonstrates that the modified Ti-Cr-Si coating fabricated by slurry sintering method can work at 1 600 ℃ for 17 h[8]. As another important potential silicide coating system, the MoSi2... coating is parabolic. The diffusion of Si leads to the phase transformation and evolution during the oxidation. Key words: niobium alloy; silicide coating; static oxidation; diffusion; phase......
="ChDivSummary">In order to explore the way to improve the adhesion of the calcium phosphate bioceramic coating to Ti substrate, the CaTiO3 coating was fabricated on Ti substrate by laser cladding (LC) using powders of CaCO3 and CaHPO4, and then the composition and microstructure of the coatings were investigated. During LC, CaCO3 can hardly react with Ti, and the coating fabricated using CaCO3 powder......
