Research on Feasibility of Med-temperature Phosphating to Replace the High Temperature Process
In order to realize the replacement of high temperature phosphating currently used in NHIC by med-temperature process, a strict test and comparison have been made for the stability, operability, cost efficiency, corrosion control feature, fastness and stickiness with the outside coating among the phosphate processes of high temperature used in NHIC and other two sorts of widely applied med temperature phosphating. It is believed that this replacement is inevitable since the superior performance of med temperature process in terms of its multi property in contrast with high temperature one. Meanwhile the quality of products is improved greatly.
