Development of Alcohol-base Coating for EPC Aluminum Alloy Castings
By orthogonal experiment,a alcohol-base coating with optimum ingredient ratio for EPC aluminum alloy castings was prepared taking french chalk and alumina powder as refractory materials and phenol resin as bonding agent,and the various properties of the coating were investigated.The application results show that this coating is suitable and cheap.Therefore it could be widely used in EPC casting processes.
