硅溶胶中SiO2含量对钛合金精铸型壳的影响
Effect of SiO2 Content in Silica Sol on Precision Casting Shell of Titanium Alloy
摘要
Abstract
The effect of SiO2 content in silica sol on the properties of coating,shell and surface contaminated layer of castings was studied.The results showed that the viscosity and thickness of the coating increases with the increase of SiO2 content at the same powder-liquid ratio,and the viscosity of the coating increases sharply when the SiO2 content increased to 14％.With the increase of SiO2 content,the flexural strength of surface shell increased gradually.The thickness of contaminated layer on the surface of castings increased with the increase of SiO2 content and thickness of castings.关键词
