Quality Improvement of Mold Shell for Titanium Alloy Investment Casting by Particle Size Distribution
Based on the analysis of particle size distribution,the practical model of particle size distribution was presented and the coating process for titanium alloy investment casting by particle size distribution was designed.Using the process,the shell specimens were prepared.The specimens were compared by the method of particle size distribution with that of common.The results show that the coating with particle size distribution is more stable and possesses better liquidity.The surface quality of the mold shell using the coating is better.The reaction between the surface with titanium alloy is lower.Therefore the method is better for producing titanium alloy investment castings.
