Surface Pretreatment & Electrodeposition Coating (PT/ED)

Course Number
This short course covers basic corrosion chemistry and the need and use of metal surface pretreatment. The effects of pretreatment system chemistry on corrosion and adhesion are presented in addition to surface cleaning chemistry. The importance of proper surface specification, several specification providers’ examples of surface specifications are presented. Detailed chemical processes for cleaning, phosphating, and chromating of metal surfaces are shown prior to beginning electrodeposition chemistry. Electrodeposition chemistry is presented as a subset of corrosion electrochemistry, showing how electric fields and current are used to apply an ED coating onto metal substrates as part of an automated production assembly. Cationic and anionic ED systems: their similarities and differences, benefits and disadvantages of each system are presented. The use of real-time electrical potential and current feedback data obtained during a deposition process is shown as a means to diagnose the ED process and equipment function. Common ED issues and coating defects that occur and how these may be identified and either prevented or repaired are discussed.
