NOVELTY - Centrifugal composite high-speed steel roll end heat treatment coating comprises hydroxyapatite/titanium composite powder, perfluoroalkyl acrylic additives, graphene oxide, nano silicon dioxide, adhesives, organosilicone modified styrene-acrylic emulsion and water. USE - Used as centrifugal composite high-speed steel roll end heat treatment coating. ADVANTAGE - The coating can be brushed on the joint layer of the shoulder and the roller neck end face, realizes the composite high speed steel roller difference temperature processing stage of the end face of the protection, avoids the temperature caused by reducing the strength of the bonding layer caused by the crack, and reduces the rejection rate.
