A chemical pickling solution for eliminating mechanical streak on the surface of aluminum alloy was introduced.The optimal formulation determined by orthogonal test is as follows:100 g NH4F,68 g HBF4,35 mL H2O2,and 0.12 g Tx-10(polyoxyethylene nonylphenyl ether) in 1 L of water,time 10 min and temperature 50 °C.The affecting factors on chemical pickling are in the following descending order:NH4F HBF4 H2O2 time.The process has advantages of easy operation,fast de-streaking and good effectiveness… CONTINUE READING
