A review on galvanizing coating defects : causes and remedies
Hot-dip galvanizing is an efficient technique to control the corrosion of substrates. Producing blemish-free coatings is a challenging task. Continuous work is done on galvanizing technology to achieve excellent surfaces; thus, flaws are encountered at intervals in all continuous galvanizing and...

| description | Hot-dip galvanizing is an efficient technique to control the corrosion of substrates. Producing blemish-free coatings is
a challenging task. Continuous work is done on galvanizing technology to achieve excellent surfaces; thus, flaws are
encountered at intervals in all continuous galvanizing and galvannealed process. Most of each very small galvanized
defect can appear like a draff particle, draff trapped actually a tiny lot of the blemishes found in hot-dipped galvanizing
coatings. Also, almost all defects take place due to a roughed or mechanically dented surface, poor bath chemistry
management, inadequate washing of the parts, and less maintained apparatus. Thus, the coated products, which are
manufactured by galvanizers, have to develop the excellence of the line instrument, the heat treatment management, and
the Zn bath in sequence to touching the hard and tough quality essential for automotive uses and applications. This review
paper first discusses different types of galvanized coating defects, and then discusses different coating defects like Bare
spot, Distortion, Dross, Touch marks, Dents, Rough Coating, Ash Deposit, Mechanical Damage, Blow out, Runs, Uncoated
or Ungalvanized Surface, Reactive and Non-reactive steels welded together, Puddling and suggests possible remedial
measures to be taken care; at the end, it summarize and concluded. |
