What is Rokide Spraying (Rod Flame Spraying)?
A ceramic rod is supplied continuously and melted in the flame caused by oxygen and acetylene gas. Then it is turned into fine particles with compressed air and continuously sprayed.
Ceramics of oxides such as aluminum oxide, zirconia and chromium oxide can be sprayed. Only completely melted materials are sprayed and the sprayed film does not contain any unmelted particles. Also, the binding strength between the particles is high so that a film with relatively rich tenacity can be formed.
