Surface Modification
"Surface modification technology" means applying special treatment to the material surface which alters its chemical composition or structure to add a new feature to the base material's characteristics. Kubota has been meeting customer needs by dramatically improving material performance through combining the metallic materials technologies it has cultivated from long experience in the casting business with surface treatment technologies.

[ Applications ]
Cracking tubes for production of ethylene and propylene are made of a heat-resistant alloy developed through Kubota's special expertise in alloy design. An oxide layer with high stability and strength is formed on the base material surface, which dramatically prolongs material life while improving the performance of other characteristics.
Combined with a wide range of base materials for various applications, surface technologies have potential to generate new products with advanced features. modification
Kubota Products Using Surface Modification Technologies
AFTALLOY
-
AFTALLOY is a next-generation cracking tube that has an aluminum oxide layer on the inside surface. The inside aluminum oxide layer is formed through special treatment processes at Kubota's plant and inspected to ensure its soundness before shipping. The aluminum oxide surface, which is a hard-to-peel dense layer that is highly stable even under high temperatures, dramatically improves the tube's resistance to carburization, oxidation, and coking. The introduction of AFTALLOY means that users can benefit from dramatically decreased cracking furnace downtime and extended tube life.
