Abstract (en)
[origin: WO2021102413A1] Methods for treating a substrate are disclosed. A method includes contacting a substrate with a pretreatment composition comprising a Group IVB metal and an electropositive metal and passing an electric current between an anode and the substrate serving as a cathode to deposit a coating from the pretreatment composition on the substrate. A method for treating an electrically conductive substrate also includes contacting the electrically conductive substrate with a pretreatment composition comprising a Group IVB metal and an electropositive metal and electrodepositing a coating on the electrically conductive substrate from the pretreatment composition. A method further includes contacting an electrically conductive substrate with a pretreatment composition comprising a Group IVB metal and an electropositive metal; and electrodepositing a coating on the electrically conductive substrate from the pretreatment composition, wherein the coating comprises each of the Group IVB metal and the electropositive metal.
